If Brad Penn works well and nobody has had issues,then stick with it.Why take a chance on cheaping out and maybe have a problem.Good oil for your motor is like good shoes for your feet! You get what you pay for.I use Z-Alt and think it's great.$50.00 a season is worth it! Just my 2 cents.. lol..
With haveing 3 cars and 1 being drivin WOT most of the time it,s running,I do about 7 oil changes per season between the 3.I was hoping someone had a cheaper alternative with the same ingredients.This way I could save for new shoes.:-\"
