Opinions on synthetic oil in high milage tahoe

[CO Tahoe]

97 Tahoe. 5.7 180,000 miles. Previous owner states it has used synthetic since he bought it. I want to change my oil but cant decide if I should stay with synthetic or go with regular oil.

I feel like I remember hearing that synthetic oil in high mileage engines is not a good idea.

Hoping you guys can help me decide.

mobile synthetic 5w-30 new rear seal when tranny was off for overhaul. original oil system gaskets and chain cover. 245,000 miles and no leaks or oil burn. just typical residue. enough said.

Go with what makes your wallet happy.

You're engine has a roller cam, I think what you are referring too is the lack of zinc additives that old (read Pre 95 GM trucks) engines need. Certain synthetics are bad in that case ...

or really old seals just leak like crazy.
