Rob, william Robison told me that if you run all syn that you should mix in at least 3oz in to each gallon, ive been running powermaster 15%(has 9% in it) because i have no need for the extra power of 30[X(][X(] but when i do have to buy it(limited choice) i put in 3oz bottle from the store. have no noises from engine like i had before when bearings thought they were at the opera

Ron, i will change my mind from the 81 to 85, thanks

opps, how that get there??
