Max Life vs Synthetic??
Ok this isnt a conventional vs synthetic thread but i need to know which is gonna be better for the z...a synthetic oil or a oil thats designed to condition seals in an older engine (ie: max life)..its had the oil changed every three thousand and thats why i believe it runs so good....but i want to give it as much protection as i can..so what are the pros and cons..any advice is appreciated
I useto use Mobil1 10W30 in my TA, I liked it alot, then I switched to Royal purple, and man I love it. It seems like the car is alot smoother, stays cooler, and I get more miles per gallon. (1-2mpg).
