over fill oil
Good afternoon, just had my oil changed on my 2020 Stingray. Got home and noticed that they put 10 quarts of oil in it. Car calls for 8 unless it's tracked. I don't track the car. Do I have a problem?
Thanks!
Dave

Thanks for the quick response. Problem solved, the service dept. made a mistake on my invoice and have made a refund for the overcharge. They did in, fact only put 8 qts in the car.
Thanks for answering my post. Have a great weekend.

2. Regarding the "calls for 8 unless it's tracked.", where did you get that from? The engine oil level, actually the level in the oil tank on the front of the engine, is the same regardless of track use. There is not a different amount of engine oil for track use.
You may be confusing that with the transmission fluid capacity/fill. Your 2020 calls for a 2 liter overfill for track use.

1. Regardless of what the invoice said, and even if it said the proper amount of motor oil - you should check your oil to verify it filled correctly. Engine oil checked with engine and oil warm, and with the engine running.

One item that shows up a lot is the mileage for the fluid change - supposed to be 45000 miles - but every so often someone posts 22,500 miles. Recently there was post where AI (stands for Always Incorrect) said it was 22,500 miles. That is true misinformation.

This. Even without the apparently mix-up on the invoice I'd check the oil myself - just to be sure. I DIY all my own oil changes, but if I use the "free" one on the C8 I will absolutely check it after they're done.

I don’t trust others work in general. I check lug nut torque after any wheel or tire service. Tire pressure, fluid levels, oil level, that the oil filter was actually changed, etc.
I’ve been lied to too many times and had poor work done even more times.
I usually do my own work because of not trusting.

One reason I did not "Take Advantage" in my two C7 dry sumps of GM's free oil changes. With two drain plugs, the newbie mechanic working the Oil Change Bay good chance it would be done wrong!
In the C7 with external dry sump tank you had to:
- Get the oil up to temperature (~175 F)
- Then wait 5 minutes for the oil in the external dry sump take to drain down from the internal baffles to get an accurate reading.
- BUT specified can't wait more than 10 minutes or enough oil would drain back to the oil pan and you'd get a false low reading!
- Lots of posts with dealer errors.
- Mine were always perfect as I took the time needed!
LoKar had a billet handle and flexible braded stainless hose that fit. It uses a flexible high temperature plastic dipstick that fits the handle and held with a set screw. BUT you have to cut the top so the bottom level indicators are where the should be! Hmm a Catch 22! So measured the metal dipstick tube and carefully marked and cut the high temperature plastic to match. When I finally filled with oil it was 8 quarts. Could not tell what pan was used, truck or car but 8 quarts looked right.looked right!
