Every time I hear someone say you have to add zinc to oil I cringe. Not because it's necessarily wrong, but I decided against it, 71 402. That's the second of two study's I've see with the message don't add to engine oil. The first praises Mobil 1 5-30 full synthetic, so that's all my Chevy gets. Funny, I noticed my engine wasn't quite purring as remembered, after my first oil change from original Valvoline Durablend 20-50 to Mobil 1. The engine loved that Durablend incidentally, but they make it differently now, so I moved on. Anyway, dollars to donuts the engine anomaly was because the Mobil and remnants of DB was less than a desirable mix. I only ran the truck in that state a few miles at most, due the truck underwent a restoration. Since then the oils been changed two more times over an entire 250-300 miles (cough). The engine seems real happy to me.

Just remembered that I also used STP on a few occasions on high mileage engines when I was in my teens and twenties. I forget what the video said about it.

Re: Video on oil and gas additives
I see that he used various oils and various additives, but did not use every oil with every additive. I suspect that the problems aren't as big as he makes them out to be. I'm definitely not equipped to prove him wrong, but I'd take this video with a grain of salt.
