Default Check when engine is cold and when warm experiment.

You will be suprised how much oil is hung up in the motor on a warm engine if you check a warm engine. I always expect at least 1/2 quart is hung up in a warm engine, if I were to check a warm engine.

Easy experiment to try at home. Use same parking spot so vehicle is same level each time. Check cold. Drive car for desired time or engine temperature. Return. Check oil after 5 minutes, than 10 minutes, than 30 minutes, than even after 1 hour. I think you will be suprised how much oil has not yet drained back into the pan.

Thanks for the great info! I just checked the oil level after the car sat overnight and it is indeed a noticeable amount higher on the dipstick! Also, the dipstick is easy to read!!

When I got my first C6, the corvette mechanic at the dealership told me before I drove off with my new car that the owners manual could answer any question that I may have about my new car.

That is not what GM says in the Owners Manual.

Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice: If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal use.
Low oil levels can damage the engine. For
information on how to add oil, see Engine Oil
on page 332.
Z06 Only: Be sure to check the oil level often
during racing or other competitive driving
and keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.
Except Z06: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
After the competitive driving, remove excess
oil so that the level on the dipstick is not above
the upper mark that shows the proper
operating range

Blow by is common during high rpm runs......this is the reason so many owners use catch cans.

Now that is said, my 07 does not use oil either. But it is not uncommon for LS eng to use some oil.

All the talk of waiting for the engine to get hot and then to dry is why I thought he had a dry sump, haha.

Wet sumps are supposed to be checked cold. If you lost 25% of your oil in a short period of time, you have a not insignificant oil leak. My guess would be doubled up gaskets at the filter. Stick your head under the car, it should be easy to spot.

Geez, According to your dipstick, you are a quart low...simply add a quart & be done with it, stop fretting

Yes, this is the correct oil checking procedure for the dry sump LS engines.


Don't listen to all the noise KingCorvette... nothing wrong with taking an analytical approach to addressing this issue rather than just "add a quart and move on."

I would personally just do a complete oil change and monitor it from there. Having bought the car you don't know truly how much oil was added during the so called "oil change" done by the dealership.

I wouldn't worry much about it. Pick up 6 quarts of your favorite synthetic oil (I personally use Pennzoil ultra 5W-30) and a filter of your choice (I personally use a WIX UP filter) and have at it. Takes 15 mins and your g2g.

Good luck.

What analytical approach would you recommend if someone didn't have clue how much oil was in the car the day he bought it and discovered 3K miles later that he was about a quart low?

Since the car should be warm for an accurate reading,
This is new to me. I am led to believe checking your oil before starting up in the morning would suffice. Perhaps with a dry sump. I take it you have a Z06, or GS? Your avatar doesn't show that.

When most people think they have an oil leak they go underneath the car to look for any wet areas of oil. The owner's manual tells you how to read a dipstick, it is pretty self-explanatory just by looking at it. Why not change the oil and just keep an eye on it? Instead of all this rocket science?

That's the age-old advice, but it's pretty meaningless for a wet sump. I've always assumed it was because of heat expansion but IMO that's not going to make any noticeable difference. It ain't rocket science.

Check it hot and cold, you won't notice any difference.





EDIT: Don! You beat me to the "rocket science" thing!

Dude... who cares? That's why I joined this forum: to ask questions that I'm not sure about, regardless if you think they are stupid or not. Quite frankly, I just don't care. If you think it's stupid and not worth your time, then just move along - skip it. Let the engaging and friendly people help me out, then (which they clearly have!).

I think it's somewhat reasonable to trust that a car has enough oil in it when you buy it from an established dealership. I get it - dealerships don't care and just want to move on to the next customer - but it's not an outrageous oversight on my part. Plus, I think the oil deficiency is from a leak, not from the dealership shorting the car on oil. You know, life is about learning, and I learned to keep a better eye out. If being a quart low after 3,000 miles is the worst of my problems, then I'm doing ok.

Default Someone asked about the exhaust tips...?

Here are pictures of my exhaust tips...

Someone asked if they had burnt oil on them?

While a lot of members here are a little **** in their cleaning and polishing behavior, you seem to have gone a different route ...

So not only don't you check your oil, you don't wash your car either. Remind me never to buy a used ca from you.
