Thread: thinking about going synthetic

Im a big valvoline fan. My 93 grand am with the 3.3L V6 (miss that motor) loved valvoline. I tried about every regular oil in that car and for some reason it ran quieter and got better mpg with valvoline. Right when i got my car I got an oil change with regular valvoline . next oil change same oil then lucas oil supplement. oil change after that switched to valvoline synthetic and been there since.
