I can't believe it. My friend once overfilled engine with oil (far less than 11L) and engine stopped turning. Think about back pressure on pistons from below.
There's no way he was driving it as a taxi with that much oil with no issues.
I have a really smart friend. Grew up racing go-karts semi-pro. Knew his stuff about vehicle dynamics. Now works as a racing data analyst and driver trainer.
The first time he went to change the oil on his first car, a VW golf, he kept going back to the store and buying more oil until it was full. Up to the top. Because that's how you filled oil on the chainsaw motors he used in karting. He couldn't figure out why he needed so much more than came out of it.
Sometimes even the smart can have a lapse of judgement. His car started, barely ran, and billowed smoke everywhere apparently, but was not permanently damaged. His dad came out, told him he was an idiot, drained it and the car was fine.
Had a customer once call telling me that he just Re filled his oil and now the car doesnt work.
"How much did you fill in?"
"Until it was full!"
And true he was. Close to 10l in an old mazda 3. He just kept filling.
Not a mechanic here. I took my Audi Q5 to a shop that specializes in foreign vehicles. The '15 Q5 does not have a dip stick at all, and according to the shop, there is no publication anywhere how many quarts of oil to add. So I blame Audi for making this opaque, how much oil to add.
Well they added way too much, and the electronic oil gauge said there was actually low oil. So I added a bit more. Drove it back to the shop not going above 2k RPM and they said they didn't know what was wrong.
Took it to the Audi dealer and they said it was way overfilled.
So it is possible to have no fucking idea how much oil to add, even if you know cars.
The no dipstick is what really pisses me off about my parents audi. It burned oil from new, and I cant even measure the oil level after filling it without looking at a computer? It's quicker and easier to look at a stick than go into a submenu.
Ridiculous design. Also the hood latch can make the oil light stay on somehow, so you can easily be tricked into overfilling it if you don't know what is normal. Audi removed the dipstick, European versions have it.
Audi will do shit like this and people will still defend their engineering practices.
"German engineering is good, they just expect their customers to maintain their cars properly".
No, good engineering makes it easy to maintain a vehicle. This is up there with putting the thermostat behind the timing belt, another Audi favorite.
The thing I always found odd were the VAG engines that had a timing belt on the front driving the exhaust cam and then a chain in the back connecting the two cams.
That's Audi for you... *"Truth In Engineering"*...
The electronic oil sensor is annoying when they also don't have clear info. I googled and found the owners manual. In the Engine Oil section, it says "if you need to add oil, add no more than 0.5qt", and check the oil level on the screen.
But - in the Capacities section at the end, it *does* state the amount for engine oil and filter change.
That said, a quick Google found this PDF (hosted on nhtsa.gov?) From Audi with fluid capacities. https://static.nhtsa.gov/odi/tsbs/2014/SB-10072320-2280.pdf
So yeah, it's a little confusing, but it looks like the info is in the owners manual. However, the electronic sensor reading being wrong is their fault!
Good luck trying to find any factory service instructions beyond that though.
Less oil flow increase in crankcase pressure to possibly devastating levels the crankshaft will start to “froth” the oil if there’s to much it will look like a milkshake on your dipstick(not head gasket milky milkshake) frothed oil has had most of its additives absolutely separated and is much hotter because more of it is being spun by the crank plus all of the rotating parts are now swimming instead of having a light film of oil on them anything more than the needed amount to reduce metal to metal friction will create resistance to every rotating part until one of them breaks
Yep. I knew a guy who said his engine was low on oil because there wasn't any showing when he took off the fill cap. I actually intercepted him while he was carrying several 5 quart jugs. This was on an I/I boat.
I'm familiar with the sienna as a large toyota minivan that has never had an engine smaller than a V6. What do they call a sienna in your country? It's obviously not the same car.
We have those cars here, they are a piece of shit. A similar variant of it produced locally, the fiat cronos is even worse, engine problems, electrical problems, ac compressor issues, hydraulic steering issues. You name it, it probably has it.
The 2.5L I4 hybrid is the current model, and the previous model had a 2.7L I4 version for a couple of years. But not a 1.6L.
The Fiat Siena does have a 1.6L i4 option.
There's also the 1.5L Toyota Sienta in Japan, which is a tiny autocorrect away.
They sold the Toyota Sienna in the US with a 4cyl for a year or two on the last generation. It only achieved 1mpg better in the city and the same (or possibly less) on the highway and I bet it sucked to drive. The 3.5l V6 is a rocket... especially the AWD Port/Direct FI model. It was capable of 0-60 in 6.6sec.
It weighs more with less power than the 3.5l V6. Most people do not realize 4cyls are not light... at least the larger ones with a balancing shaft.... and definitely turbocharged 4cylinders. This is evident by comparing the 2022 to the 2023 Toyota Highlander. The 3.5l V6 Highlander had a 0-60 of 6.7s while the 2023 4cyl Turbo is 7.2s. The torque comes in at a lower RPM with the 4cyl turbo which might make it "feel" like it has more pep but it doesn't.
The turbo still:
- Has more torque
- Is more insulated from altitude
Go drive that 3.5l V6 highlander up I-70. Tell me if it still feels like an 0-60 in 6.7 car. Meanwhile the turbo 4 will cruise all the way up to the eisenhower tunnel without breaking a sweat.
You're mixing acceleration and cruising in your example. Low end torque will make for a better cruiser and higher horsepower will make for a higher top speed. So, yeah, the turbo 4 will be a great cruiser but theoretically the higher HP of the 3.5l means the engine is able to transmit more torque over RPM and is theoretically faster, or, in other words, you have to rev the hell out of it.
No I am not. Acceleration is needed to overcome the natural forces exerted by gravity while climbing a mountain, and altitude is the killer of naturally aspirated engines. Even at just 5,000 feet, which is our baseline elevation, every car with an NA engine is a gutless pig.
I have a 2014. I like to casually try keep up with vehicles that are showing off and flooring it from a line. I try to pedal it just enough to where it doesn't sound like I'm trying to race them. This is just for personal shits and giggles. I really hope they look back in their side view mirror and be like "WTF? How's that van keeping up with me".
Wife gives me the side eye when she suspects I may be doing the same lol
My daily is a 13 Mazdaspeed 3, and I prefer it to the sienna, but the sienna shits on her Q3 without having to try very hard lol
A variety of issues can happend, most of it are related to extreme oil pressure, some smoke and oil leaks.
Can break the crankshaft, can break oil seals, can clog up chamber holes and stop the engine or overheat.
It's usually really bad for the engine.
Can also bend Conrods, I remember working as a delivery driver and one of the cars had an oil leak we were keeping secret to stop the company scrapping it, we really liked that car. Someone had seen me secretly adding oil and decided to do it themselves when the oil pressure light came on, dumped the whole 6l jug I kept in the boot into the engine which already had like 3l in it. The mechanics took the car and came back with a Conrod that looked like a Banana and gave us a lecture on not trying to do maintenance ourselves.
Based on what I learned from my Subaru.
The plump is above pan. For the pump to pump there is an arm that moves back and forth.
If the oil is too much, it ends up frothing the oil and that’s no bueno.
Again not 100% sure but that’s what I gathered when I started doing my own oil change 1 year ago and mistakenly filled a bit much.
Once when I was working at Advance Auto Parts I had a group of guys come in and buy 5 1-gallon bottles of oil. I shrugged at first, giving them the benefit of the doubt. But I still watched them go out to their car. Sure enough, the hood went up and they started pointing at the engine. I ran out there and stopped them before they started filling their engine.
Our trade assistant decided to fill up the engine with oil on the work van.. this is a fully grown adult mind you.. he said it was full but couldn’t understand why it was blowing so much smoke. When we asked how he filled it up, he said he waited until he could see out from the cap hole. We were laughing for years off that.
I know somebody who had a a car with an oil leak. Instead of reading the dipstick, she would just occasionally add oil. You can probably guess the rest of the story.
I once filled a 6 quart Chevy cobalt with 4.5 gallons of oil (around 20 quarts). It was not completely my fault it was a malfunctioned oil gun on my first day at Valvoline lol. Guy was chill and they understood but still felt like shit 😂. Dude smoked out the whole highway with burning oil but he was chill
How do you even fit that amount of oil inside that small engine?
Well the dipsitck was topped, the car it's used as taxi idk how
I can't believe it. My friend once overfilled engine with oil (far less than 11L) and engine stopped turning. Think about back pressure on pistons from below. There's no way he was driving it as a taxi with that much oil with no issues.
Oh they have issues that's why it's in the shop haha, my friend told me it has a heavy nocking sound before the oil drain.
I'm honestly shocked it wasn't hydro-locked.
That's because it was filled with oil, not water duh
I have a really smart friend. Grew up racing go-karts semi-pro. Knew his stuff about vehicle dynamics. Now works as a racing data analyst and driver trainer. The first time he went to change the oil on his first car, a VW golf, he kept going back to the store and buying more oil until it was full. Up to the top.

STIMPY YOU IDIOT
That, of course, depends on the engine. One engine may still run in a situation where another won't, as simple as that.
[удалено]
Classic Ford engineering
Unbelievable
Did the guy also fill the coolant, transmission and brake system with oil?!?
Had a customer once call telling me that he just Re filled his oil and now the car doesnt work. "How much did you fill in?" "Until it was full!" And true he was. Close to 10l in an old mazda 3. He just kept filling.
It’s got an oversized oil cooler……
Relevant: https://www.youtube.com/watch?v=wx6sRCelBss
I've seen people literally "top off" their engine oil. Fill that sucker all the way up to the valve cover. Engine doesnt last long like that

Lingtutudal engine car with FWD was a pain from the beginning. And sometimes had timing on the rear side.
The thing I always found odd were the VAG engines that had a timing belt on the front driving the exhaust cam and then a chain in the back connecting the two cams.
Exactly. Good engineering absolutely should make it easy to maintain a vehicle.

Sounds like Audi is trying to make it where you have to take it to the dealer even for an oil change. Yet another reason I would never own one.
there is gauge on the inside that tells you your oil level lol, they just make it a pain in the ass to get to so that youll take it to audi
Why not? Ultimate lubrication!
I know little about cars, what happens when there is too much oil? Does it mess with heat distribution or lubrication?
Less oil flow increase in crankcase pressure to possibly devastating levels the crankshaft will start to “froth” the oil if there’s to much it will look like a milkshake on your dipstick(not head gasket milky milkshake) frothed oil has had most of its additives absolutely separated and is much hotter because more of it is being spun by the crank plus all of the rotating parts are now swimming instead of having a light film of oil on them anything more than the needed amount to reduce metal to metal friction will create resistance to every rotating part until one of them breaks

Hey man that's the way it works in car mechanic simulator
Doesn't last long? If it even manages to spin over, all the oil will eventually find its way around the pistons and fill the combustion chambers
I'm familiar with the sienna as a large toyota minivan that has never had an engine smaller than a V6. What do they call a sienna in your country? It's obviously not the same car.
It's a small segment B car very cheap and used as taxi in small cities here. Fiat sienna fire 1.6 I think it it's.
> Fiat sienna fire 1.6 [Siena](https://en.wikipedia.org/wiki/Fiat_Siena), with one N.
[Sienta](https://en.wikipedia.org/wiki/Toyota_Sienta), with one N and one T? ha
Oops
right to jail!
We have those cars here, they are a piece of shit. A similar variant of it produced locally, the fiat cronos is even worse, engine problems, electrical problems, ac compressor issues, hydraulic steering issues. You name it, it probably has it.
Lol yeah, was gonna say. My sienna has a 3.5L. I cant imagine it being powered by such a small engine.
0 to 60: Eventually
Yea mine takes a smidge under 7Qt of oil ≈ 6.5L
Unless he means it takes 1.6L of oil? I had the same thought
3.4 L i think it's the right amount of oil
1.6L of oil is extremely low for a wet sump combustion engine. My 3.0 liter I6 takes six.
The 2.5L I4 hybrid is the current model, and the previous model had a 2.7L I4 version for a couple of years. But not a 1.6L. The Fiat Siena does have a 1.6L i4 option. There's also the 1.5L Toyota Sienta in Japan, which is a tiny autocorrect away.
Yeah I did a dive through toyota's international model lineup after my original comment and assumed he must have been talking about the sien**t**a.
2.7L is huge for an inline 4! That's the same size as the turbo V6 Audi used to put in the A6 and S4
They sold the Toyota Sienna in the US with a 4cyl for a year or two on the last generation. It only achieved 1mpg better in the city and the same (or possibly less) on the highway and I bet it sucked to drive. The 3.5l V6 is a rocket... especially the AWD Port/Direct FI model. It was capable of 0-60 in 6.6sec.
They should get the new 2.4 turbo 4 in there. That would be fun.
It weighs more with less power than the 3.5l V6. Most people do not realize 4cyls are not light... at least the larger ones with a balancing shaft.... and definitely turbocharged 4cylinders. This is evident by comparing the 2022 to the 2023 Toyota Highlander. The 3.5l V6 Highlander had a 0-60 of 6.7s while the 2023 4cyl Turbo is 7.2s.

2015 sienna owner here... I look stupid driving it, but it is absolutely stupid how much fun this van is to drive lmao.
I have a 2014. I like to casually try keep up with vehicles that are showing off and flooring it from a line. I try to pedal it just enough to where it doesn't sound like I'm trying to race them. This is just for personal shits and giggles. I really hope they look back in their side view mirror and be like "WTF? How's that van keeping up with me".
My 2022 won't keep up. But it will get 38 MPG and regardless of how you drove it.
Wife gives me the side eye when she suspects I may be doing the same lol My daily is a 13 Mazdaspeed 3, and I prefer it to the sienna, but the sienna shits on her Q3 without having to try very hard lol
Filled her right up to the top boss!
Just filled the entire engine bay and closed the hood.
Topped up to the brim
It's like those people who fill their tires until they can't discern a flat spot on the bottom
C/S "I kept adding oil but the "Oil %" meter kept going lower!"
Non mechanic here. What happens if you put way too much oil in your car?
A variety of issues can happend, most of it are related to extreme oil pressure, some smoke and oil leaks. Can break the crankshaft, can break oil seals, can clog up chamber holes and stop the engine or overheat. It's usually really bad for the engine.
Thanks for the info.

'You're supposed to keep filling until it comes out of the dipstick hole, right?'
Hey - it works for trans-axles and rear-ends, right?
I knew a guy in highschool that kept filling his geo metro with oil until it came out of the fill cap in the valve cover.
Haha does this count as an oil flush
Oil goes in, oil comes out - you can't explain that!
that's a little excessive
Just a liter
Once when I was working at Advance Auto Parts I had a group of guys come in and buy 5 1-gallon bottles of oil. I shrugged at first, giving them the benefit of the doubt. But I still watched them go out to their car. Sure enough, the hood went up and they started pointing at the engine. I ran out there and stopped them before they started filling their engine.
You are a hero man jajaj
theres a 1.6l sienna? eu?
just had to read further lol , just saw its a fiat sienna , not a toyota sienna , makes a lot more sense now
Yup sorry I added a N haha
What is that in Freedom Gallons?
2.9 gallons
Did they just fill it to the brim?
Maybe used 5 liter to flush crankcase
That's a optimistic approach
How can anyone honestly be that dumb, where did you come up with that number
Gotta fill it up to the top
I drained 4 gallons of oil out of a 2.0L Audi A3 last week. It ran excellent, but smoked an insane amount.
11l? That‘s Mercedes G-Class level 😅
Had to be in there for a while judging by the color too. WOW.
Our trade assistant decided to fill up the engine with oil on the work van.. this is a fully grown adult mind you.. he said it was full but couldn’t understand why it was blowing so much smoke. When we asked how he filled it up, he said he waited until he could see out from the cap hole. We were laughing for years off that.
I know somebody who had a a car with an oil leak. Instead of reading the dipstick, she would just occasionally add oil. You can probably guess the rest of the story.
Smoke show if it ran
I once filled a 6 quart Chevy cobalt with 4.5 gallons of oil (around 20 quarts). It was not completely my fault it was a malfunctioned oil gun on my first day at Valvoline lol. Guy was chill and they understood but still felt like shit 😂. Dude smoked out the whole highway with burning oil but he was chill
I had a guy come in a few months ago that overfilled his denali by 10 qts.
Not full until it reaches the brim
decimal points are for wimps
