There are things I worry about, but foaming engine oil isnt one of them. I've used plenty of Rotella in my work and private life. Never an issue. IMO all the major branded diesel oils are decent. I always preferred Mobil, but thats mostly loyalty to the brand as I have always had good luck with...

Carbs need to be tuned for the oil ratio amongst other variables.

Pablo, at one time I owned and operated a Candian fishing lodge with many Yamaha outboards of various sizes. The non oil injected ones all called for 100:1 mix oil ratio. What we found was that motors ran on 100:1 started to lose a bit of power significantly sooner than those ran at 50:1...

One other thing. Red Armor formulation changed a few years after the initial marketing was put out. It was an ester blend. It appears it no longer is last I checked.

Not that I have seen. And its hard to clean when your laying down deposits also.

Various years from 2003-2008. 90hp 70hp 30hp 3 cyl, 25hp, 15, 9.9, 8, 6 off tge top of my head. The largest number being 25hp models. We ran one a bulk tank with 50:1 mix. The injected models got 50:1 and oil injection. We ran all tge camps for cycle stuff on the same mixed fuel too.

I have used information tutorials on car repair, but for any sort of technically accurate stuff its much less useful

I have better things to do than sort through the garbage there. Most of the content is terrible as in the majority of it.

I will try it and get back with you.

Are you talking about the Berrymans carb dip? If not which product?

Gasoline will not dissolve carbon off a piston. I dont think Berrymans will either, but to be fair I havent tried it.

BTW this motor has for most of its 5 year life ran on Red Armor starting from new. Its a decent oil, bu the stuff isnt magic. There are other cleaner oils out there.

In the first video it shows very minimal change in the transfer port wash. What did change greatly is the RPM of the motor both at idle and at peak. A properly tuned motor will run cleaner. The other is just marketing drivel.

When I get a chance I will get some more Red Armor and document via pictures what the engine looked like before and what it looked like after with bore scope pictures.

Good, post a link to one. I inspected with a bore scope... The only thing that will remove carbon from a two cycle piston crown is running the motor excessively rich while under

Good, post a link to one or show me your results. What I have seen are claims with no visual evidence. I inspected with a bore scope... In my expiereance the only thing that will remove carbon from a two cycle piston crown is running the motor excessively rich while under heavy load. In time...

No. Better air filtration would be more useful for that type of use IME.

People make all sorts of claims that are BS. That and people flat out lie. I ran a test some time back with pictures using Techron after a member of this forum claimed on another site that Techron cleaned up his Stihl 4mix engine. The results where that it did nothing and this included letting...

I use it. I've inspected with a bore scope. I have seen the marketing speak. As for you tube. Its probably the worse source of information in cyberspace.

Just the truth.
