Hey,
I was thinking putting in some Pennzoil Platinum or Mobil 1 in my 92 Ford F150.
I've got 214,009 miles on the motor.And I've been useing Pennzoil 10-w30.
Would ya'll change or keep putting the same oil in the good old motor?
Do you think the synthetic would help the old motor ?

It won't hurt the engine. It might start leaking like a sieve though since the synthetic will do a better job of cleaning the crap out of the seals and gaskets. Of course, that crap is keeping the regular oil in..

You don't want to use a synthetic now. Any of the PAO synthetics will have some form of ester to bind the add pack to the basestock. This ester will have great solvency and will remove any varnish or sludge you may have in the engine. I'd bet money on a lot of leaks. I would stick with the oil that got the ol' girl this far.

I wouldnt switch to a synthetic now. Like the others have said, lots of cleaning action going on and leaks will develop. That and I wouldnt worry about putting synthetic in an engine with that kind of mileage. I would stick with dino, it done took the motor that far, might as well keep using it.

I kept with the same oil that I have always used in the truck.
You hear all sorts of stuff from the guys at work.
But when it all comes down to it,ya'll are right.
The reg.oil has done a good job so for so why change now.
Maybe the old ford will run another 2,000,000 miles or more.
The motor hasn't been apart on the inside.
Thanks
