It’s time to talk motor oil! I have a feeling you wouldn’t be reading this if you weren’t a car guy like the team at CorvSport is, and if you are like us, you want to make sure you use the best and most popular products for your beloved Corvette. Oftentimes, we enthusiasts with gearhead mentalities like to do as much maintenance and wrenching as we can ourselves, and what is better than crawling under your Corvette to change the engine oil and get some fresh blood in your LS veins? And a bonus if you spill a little on yourself and get to smell that lovely used oil essence for a few hours! [Author’s Note: This article is FREE and not behind a paywall.

For today’s CorvSport Curates feature, we compiled the community recommendations from the largest Corvette Forum in the country. In an effort to present the most meaningful data, CorvSport combed through four lengthy and spirited oil discussions containing 100s of posts and ranked the top choices from hardcore enthusiasts. These recommendations are fully credited to the Corvette Forum. To avoid duplicity among members, we chose thread discussions that were at least two years apart, and these ranked results span discussions from 2010 to 2019.
