The power of beer
Ok, I have a '99 Silverado with the 5.3. The truck has about 83,000 miles on it and is burning about a quart of oil every 800-900 miles. There are no leaks anywhere that I can find, it is just using it. I have changed the PCV valve and am currently running 10w-30 Havoline motor oil. I am also using 2-3 quarts of the Lucas oil stabilizer, but it hasn't helped. If anybody has any suggestions on what I might try to slow this down or what might be the problem, please let me know. Thanks.
