Personally, all I've ever used was injector cleaner, good to know that's a good idea, but really then, I need to use it more often.

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.

Same here. I've used Chevron Techron fuel system cleaner a few times. But I've always thought adding additives to motor oil that already has an additive package was not a good idea. The tests in the video showed it was worse than I thought! The only one I've ever used was Comp Cams #159 break-in lube, but lately I've used only Driven break-in oil along with their HVL assembly oil.

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.

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.

I use Seafoam as a fuel detergent only, in gas AND Diesel engines. It has worked in those situations on several engines.

That what I use it for also.

I have had great results.

If an additive adds, let's say, 100 ppm calcium to a test oil, then we can expect it would add that amount to virtually any oil.

True enough. But at the end, he was talking about other oils and different additives, not base oil. Some of those oils have their own additive packages which other additives could drive the numbers above factory spec. I only ever have added STP in my truck, mainly due to the age of the engine. I'm rethinking that, based on what this guy reported in his results.
