Switched from synthetic to conventional oil after talking to that old guy at the NAPA in Tulsa

He showed me the inside of a 350 Chevy that ran 200k miles on dino oil and it was cleaner than the one I just rebuilt using full synthetic, so now I'm wondering if I've been wasting money for the last 10 years, has anyone else run into this or am I just getting bad advice?

My dad was the king of taking advice from dudes at parts stores, and he swore by conventional in his old F-150. Ran that thing 180k miles before he sold it, and it never burned a drop. Meanwhile I spent $400 on synthetic for my Accord last year, and I'm pretty sure the valve cover gasket started sweating just to spite me. Take this with a grain of salt because I'm the same person who once bought a 'lifetime' air filter that clogged in three months.

Dude yes, same here! My buddy swore by that cheap conventional oil in his old Silverado and that thing hit 200k with zero issues, just regular changes. I went all fancy with synthetic in my Civic and suddenly had a leaky timing cover seal at 80k, made me feel like a sucker for spending the extra cash. Makes you wonder if these older engines just vibe better with the basic stuff, lol.

That 350 Chevy was probably maintained better than most. Synthetic is good but it can't fix crummy maintenance habits.
