Hello all. I have engaged in an argument with a friend of mine about the best choice of oil to use in our Chevy Cobalts. I have an '06 2.2l with about 74k miles. Here are the options we are arguing over:
4 quarts 10w40 with 1 quart Lucas Heavy Duty Oil Stabilizer
if you change regularly, like 3-4months it really does not matter. I use mobil 1 5w-30 full synthetic(have to use synthetic in the SS/SC). Extended changes like people who go 5000 miles or more might not be a bad idea to add the stabilizer but as long as it gets changed and driven without much beaten on the motor I dont see the since in stabilizer.
