The secret to longevity to any vehicle is synthetic oil and wix filters. Regular air filter(20,000 miles) changes only add to the number of trouble free miles.
That's interesting... what makes synthetic the "secret to longevity"? Sure, it's better, but it is "better enough to make a difference"?
I've never run a wix filter, and never run synthetic unless the manual called for it, and I have 2 vehicles over 200K; coincidentally, it's my GMC truck that has 320k on it without ever having had synthetic or wix filters... just proper maintenance with the oil called for in the manual...
I'd have put you more in this:I voted for two. I have a F-350 crew cab 4X4 long bed diesel and a GMC 1500.
Synthetic is better to a point. I do not run it in my as delivered vehicles but anything making power gets synthetic.
