If the car has fewer than 50K, or has been maintained perfectly, you shoudl go ahead and switch to a synthtic oil like mobil 1.

Otherwise, just switch to the typical dino oil, synthetic will burn.

for a 92, I would go with the 10W in the summer, 5W in the winter. (I am assuming you have over 110K)

just curious, why would it burn synthetic oil and not burn regular oil?
also, what do you mean by "...has been maintained perfectly..."

here we go...no it wont.

and it wont cause leaks either.

Everything you ever wanted to know about motor oil!


i switched a 1992 explorer to synthetic at 600,000 miles (dont ask, i only had it for about 5K)

and a 1987 Ranger to synth at 220,000 miles.

no leaks there.

well that's why I asked. just want to know what the theory is based on. I think if the car burns oil, it will burn any oil. If it doesn't burn oil, it won't burn synthetic nor regular. Normal oil consumption is what's expected. Any engine burns oil. Even on a brand new Lexus. If you drive for 5,000 miles without checking your oil level hoping that it will be the same as when you filled at oil change, you are in for a surprise.

Why in bloody blue hell would you ever buy a vehicle with 600,000 miles on it?

it cost me $50.

it wouldnt start. the guy said he thougth the engine was seized (i was thinking of a 5.0L V8 swap!!). i looked uder the hood and could see nothing visibly wrong, so i towed it home. i started palying around. wth stuff... i found the starter to be the source of the problem, along with the Distributor.

so for $400, i got a great working truck.

i sold it for $1500.

Just as my questions faded away, so do my doubts of your intelligence.
