i got 1 for you guys. i dont and cant recall ever using fram but i have for as long as i can recall been using wix. i use wix on my drag car pickup and the kicker my semi. the abuse my cat holds almost 70 psi at hwy speed which is almost all day long almost every day and if its hot or really cold never gets shut off till i get home. this motor had just under 2 million miles on it when i sold the truck. i only use wix for oil fuel and water with 9 gallons of rotella and 1 gallon of lucas changing the oil every 10,000 miles. i know its not the same as a drag racing motor but still thats alot of miles and alot of hours.
fram? whats a fram?
