Huh?????????????????
I read that in the OM. How accurate in the Lie-O-Meter on the 6. 7s?
Hmmmmmmmmmm, I run miles. Lots of miles. Hoping that will keep the engine cleaner than sitting in stop and go traffic.
I run Stratapore filters. Truck has 57,000 miles so I only have 43,000 to go until I am out of warranty and hopefully I will have done enough research to make a semi intelligent decision concerning the left wing devices installed on the motor.
