Oil changes-do you fill to the max point on the dipstick or the middle?

[esandes]

What do you do? Is there a risk to fill it to the max level on the dipstick?

[ImAudiHeree]

Nope no risk and most of time when do oil change the oil filter sucks some out anyway so always double check level after done.

[aluthman]

Do you only fill your gas tank halfway also? There is probably more harm in only filling it halfway.

Are we serious right now? Must be trolling us

All of the garages that change the oil keep it halfway. So I just top it up. I wonder why they do that.

[vvenom800tt]

Maybe you should change your own oil. Your shops are obviously idiots.

Spend a few bucks on a pair of ramps.

Who voted half way?

Drain the oil, measure the oil that came out, then put in the same amount that drained out.

Best cheapest ramps are made from 2x6 lumber.

you sure as hell dont want to do that with a B8 :) you'd be putting like a litre and half back in lol

Assuming you have no leaks and burn no oil... I just drain it, add 4 quarts, check level, add as necessary until full.

Fill to Max ... and keep a spare quart in the boot ... because Audi.

[Brillo]

Who voted half way?

I did, and here's why. The plastic stand-offs on my original dipstick started to degrade so I bought a new OEM dipstick at my local dealer. The oil level that measured full on my original dipstick only measured half-way on the new one. I checked the oil level using my two friends' OEM dipsticks and both measured different levels. Therefore, after an oil change where I know exactly how much oil I've poured into the engine to reach the full mark on the old dipstick, it now measures mid-way on the new one. I burn about 1/2 qt during the OCI so I top off with 1/4 qt half way through the OCI. Make sense??

I keep spare everything now a days. Couple of times, I had ignition coil fail on the freeway. My trunk always has 1 quart oil, 1 ignition coil, T20 screw driver, 17mm socket and ratchet, impact wrench and an oil change tool kit.

I try to keep my car at least 3/4 full on the dipstick. That isn't an option on the poll so I didn't vote 😋

AFAIK adding more oil to the car beyond the low line only increases thermal capacity and stretches out how often you need to change your oil, but I'm no engineer. The 2.0T BWT engine calls for 4.8 quarts with a filter change included, but bottom of the dipstick is ~4 quarts so that's what is REQUIRED to run the engine. I wouldn't be concerned about the oil level being halfway on the dipstick in any situation.

^Also this. If you're concerned about your oil level in the first place you should already have a spare quart in the trunk (I always do). If not then you're doing it wrong.

Because Audi.

[Jayz691]

You can always check it with vcds, then no question if your dipstick is right, lol. I just say this cuz recently seen you can do it, when messing around with my Obdeleven. It was at 72mm, lol.

Specs read to apply 4.5 qts; this results in half way filled. There is more risk of overfilling than underfilling the volume of oil.

[esandes]

nicht überfüllen!

Damn. Ok I won't be topping it up to full anymore. My other car is right at full on the dipstick when the spec amount of oil is added.

thank god you arent a mechanic. first of all its 4.8quarts then any engine in the world is designed to handle overfills upto 1 liter. anything over that, you car starts smoking untill the extra oil is gone or if its way too much, it will knock out cam,crank seals and foaming in oil begins to start.

lets talk about underfill the engine. nothing good comes out of it. first turbo starts getting cakes, cams and head suffer oil deprivation eventually you will have a balony for an engine

[Brillo]

...any engine in the world is designed to handle overfills upto 1 liter.

Would definitely not want 1 liter overfill in this engine. I would be willing to bet that the crank counterweights and rod end caps could be rotating into the oil and foaming it. Air entrained into the oil can really mess up an oil pump and bearings. Splash lubrication may be OK for a Briggs and Stratton but not this engine with all its oil related proclivities.

[Theiceman]

Brillo is right on the money .... you are better off 1 liter low for arguments sake instead of one liter over. Newer engines including including Audi actually warn you to drain oil as it senses it is overfilled.... now you might imagine why I m saying this , and it is the points noted above..

firstly lower volume of oil will not cause oil pressure issues .. oil pressure is the flow of oil from the pump vs the restriction provided by galleries and bearings.. that's it .. the only way low oil level will cause low oil pressure is if you are drawing air at the intake to the pump... remember im not talking almost empty just a quart low ... the bigger downside of low oil level is heat dissipation , just not enough volume of oil to keep cool and cool off before it is reused and pulled out of the sump. Plus of course quicker contamination. The other obvious effect of lower oil is the risk of
ingesting air due to high Gs that might expose the oil pump pickup and cause starvation as this engine really has no baffling in it , and really should need it , its not a race car .. but normally you go a quart low , big deal you fill it up and on your way , i think you could likely not harm the engine being even lower , but i don't know how much the engineers put in reserve so wont comment .

Over filling by a liter ? and modern system will warn you immediately. The technical word i think you guys are reaching for is oil cavitation and it is very bad. it happens instantly when the motor starts and you have you have relatively large % of air in the oil that now enters the bearings and other friction surfaces. I would argue that any amount of cavitation is worse than being some what low on oil. is you are injecting air into the oil on every engine stroke regardless of driving or car conditions.

I guess how much overfill causes cavitation . vs how low on oil causes starvation may be the discussion here. I don't think any of us are qualified to make that determination.

well said. I think windage trays in the modern cars will handle overfill about 1/2 to 1liter not saying that you should it. I had a sebring 2.7liter(it had a nickname called sludge master) not too long ago which was designed poorly by mitushibushi motors. The oil pan was designed for 5 quarts but engine would starve oil ( I am not saying it. Engineers found it) and start scoring cams. I used to overfill it upto 1 quarts to avoid it. Even in my 2.0T I fill 5 quarts because I didnt wanna leave that 0.2 quarts in the can.

Again its just my opinion and comes from my experience.

We’re kinda veering away from the original question of whether to run with your oil at the full mark or to run it at the halfway point. Filling it to the full mark is NOT overfilling it and will not hurt anything. Running it at the halfway mark will not hurt it either, BUT you have less margin for things like cooling, contamination, oil consumption, etc. why anyone would not run it at the full mark is beyond my understanding.
