Hello fellow enthusiasts,
There has been numerous debate over the correct refill quantity after an oil change on c5.
After many questions, GM has sent dealers a VME on this issue.
The correct oil refill is 6.5 quarts. If you install 7, you will aerate the oil, and it will be consumed by the PCV system.
You will NOT see a full mark, directly after priming the oil filter. IT may take as much as 5 hours for all the oil to drain back into the pan, and give you a full mark. This is why you may see a 1/2 quart over full first thing in the morning if you put 7 quarts in.
This is the official word on this, as I have been authorized to release this.

oil change frequency

on a related note, while reading through the manual (just brought my baby home) I was astonished at the recommended oil change interval....... 15,000 mi or 1 year. Wow. Bet the oil change depots would never tell you that.

I find it hard to reconcile changing oil at 15,000 miles. I have always changed at 2800-3000 using Castrol. My Z06 has synthetic Mobil 1 and I plan on changing every 5000 miles. It might be more expensive but it would give me peace of mind.

hI there,
This oil change interval is based much on your driving style. That, in conjunction with the tri synthetic technology of the Mobil 1, all work together. Please understand, use your oil life monitor, as it is still slightly optimistic to the safe side, so you will not ruin your engine.

I have a peoblem. My oil is full, I check it always but now I get a "Low oil level" on the DIC. It was low and I filled it up. The Low oil level went away, but now it came back. Any ideas why? Does the oil sensor need to be replaced? Thanks in advance.

Hi there,
How much oil did you add???
c4c5:hb
It was a quart low so that is how much I added. The "Low Oil Level" went away after that, but now it is back. It goes on when I start the car, while driving, and when I turn the car off. I check it everyday and it is full. The car drives fine as well.

Hi there,
I would say that your oil level sensor is not reading correctly.
It is very simple in design, and I am sure that your local dealership can correctly diagnose the condition.

Thanks c4c5 specialist. I am taking my Vette to the dealer for them to look at. I told them that it is probably the sensor since the oil is full. They will check it out and let me know. Thanks again.

Oil change

After my last oil change, I check the gauge the next day. It said Oil life 69%...WTF? I called the dealership, they said that the mechanic must have failed to reset the gauge button (I'm wondering, what else he may have failed) and that I should go to that setting and hold the button down. It was simple and it was reset to 100%. WHEW!

E Chick.,,, not unusual to happen. In my owners manual (2002 Coupe) it states to "not to forget to reset this."

Question to c4c5Specialist, with the normal low mileage given to the Vettes, is the oil monitor the primary source for changing oil? What about a car that is not driven on a daily basis and will not get 15K miles in a year's time frame?

HI there,
Yes, your oil life monitor will take into account all driving styles and information.
I usually suggest that when your monitor hits 25%, make an appointment, or change your oil.
This will still give you plenty of time to change it.
