And guys.... Be cool. This is an open forum here. It is not good to be carrying on about redundant topics. These type of threads happen ALL the time on here. And there's nothing wrong about that in my way of thinking. How many threads are like "what kind of oil do you recommend for my car/truck?", " Can I switch to a synthetic oil with a high mileage vehicle?", "Can I switch back and forth between conventional a synthetic oil?", Which oil do you like more PYB or Valvoline?", Is group 3 a real synthetic?" Etc etc... It is par for the course. And that's all right at the end of the day.
