Ive got a 94 5.0 and have been running 10w-30 from Chevron for the last while and I've thought about making the switch to synthetic. Is that a bad idea? Because I've heard only to use synthetics on a new car for the sake of the seals...

So my question is: should I start using synthetics with my car if its got 60k miles on it? And besides upping the life of my stang, what pros and cons can I expect from the synthetics?

I started usin synth on my car at 70K miles, my dad at 50. The buick.....that still gets dino, wont' get synth ever.

The only con of synthetic is it's higher price. But the pros outweigh it if you care about the motor.
