my vette has 29,000 mile and when i checked the oil it was 1.5 quarts low!!!!!!!, I had changed the oil 5,000 miles ago, I only diff. in driving is that I ran it up 145-150mph on the interstate a few time in the last few weeks, I have no leaks, is this a ring problem, or can you expect that when running at high speeds? :confused:

 

1.5 qts. in 5000 miles is in the range of normal consumption. Especially with some high-speed runs in the mix. Add the oil and don't worry.

 

I agree - perfectly normal.
