Did my oil change recently. If my car is parked at a very slight incline it'll be 1 bar less. If it's on a flat surface...all bars to the top.

My gauge was at full bars when I had the oil changed at the dealership. I honestly don't know, hard to determine without dip stick.

Hard to believe just 7.5 qt.

Was it with filter change?

FYI, my 2007 takes 8.5 and it reaches the H mark. The gauge never shows overfilled like yours.


Just drain a little ASAP and measure again. Overfilling is never good.

Agreed, hard to believe 7.5 qts could overfill. Drop the filter and pour out the oil in the canister.

Just drive it off. Mine always came back from dealer that way, 1/4 qt "overfill" will look like that. The steps on the digital readout don't help. Drain it a little better next time or add just 7 qts and then top off. I initially panicked and drained 1/2 qt only to get a one bar low reading.

I have overfilled it before too but I never got the error light. If it were me, I would drain and not take chances. Heck, a veteran mechanic friend of mind once forgot to put the drain plug and he just found out when he was standing in a pool of new oil.

Bottom line is that we all tend to get confused. Worst case, OP might also have a bad pressure system or something else if after draining the error light continues to be on.

Drain it: 5-10 min of drain ain't worth the possibility of damaging a $20,000.00 engine.

IMO!

Yes, and if it's overfilled, doesn't oil get blown into the combustion chamber and then you get smoky exhaust for who knows how long?

OK quick google search shows a couple of similar answers:

Dangers of Overfilling

  • While it may not seem like a big deal to overfill the oil in your car, it can cause major malfunctions and potentially cost you thousands of dollars.
    When too much engine oil fills the crankshaft in your car, the oil becomes aerated and is whipped into foam. This is caused by the high rotation of the crankshaft. Foamy oil cannot lubricate your car well, and in many cases it will cause oil flow to halt completely, overheating your oil and causing loss of oil pressure. The engine then becomes starved for lubrication and may potentially lock up.

What happens if engine oil is overfilled?

As with any car, it depends on how much extra oil is added. If enough extra oil is added, the oil level will reach the crankshaft throws (i.e. piston rod connections), and get whipped up into a froth (like a latte) as air is mixed in with the oil. If the froth gets sucked in by the oil pump for circulation through the engine, the surfaces that are normally lubricated by constant film of oil may instead have air injected on their surfaces. This is not a good thing. It's almost the same as having too little oil. If you think you put in too much oil, and you see a lot of foam on the dipstick afterwards, you may have to drain some of the oil out.

I personally am happy with the level being one bar low - I just check it after every gas fill up and top off if needed. I personally would drain out some oil.
