A subject near and dear to my heart . . . on many levels.
Many of you know I bought a new truck a couple months back. Well, I'm a purist. I don't like fruit in my beer, I drink my liquor (Jack Daniels) straight, I smoke my cigarettes unfiltered (Camel), and my cars are American. That's just the way I am. Mrs. F is used to it.
Anyway, synthetic oil is out for close to 25 years now and I figured I would try it, finally, in one of my vehicles. We have about 7 or 8 customers who have used synthetic oil in their cars since they were new. (We'll put whatever kind of oil you want in, provided it meets manufacturers spec) Guess what, I'm finally convinced. It makes a difference.
One car in particular, an '89 Pontiac Firebird 5.0, has close to 300K on it and I've never been inside the motor. Runs like a champ. Another is a Ford Ranger like mine, same motor and trans, 10 years older, synthetic all its life. 180,000 miles, never opened her up, only routine maintenance (brakes, tires, battery, oil changes, etc). I'd tell you about the Mercedes with a half-million on the clock, but it's a Mercedes, you expect that. If I get 250K out of my truck, I'll be a happy idiot. I'll let you know how it goes.
But remember, Lugnut, I'm still gonna change the oil EVERY 3000 MILES.
By the way, I've had the damn thing 6 weeks and just passed 2000 miles today. I'm gonna be doing a lot of oil changes.
