ekpolk we had a lot of conversations about doing that in Wankle engines and in diesels with standyne pumps in them. I have down it for years as well. I have to admit I have not done it in a long time my 1986 Toyota 4Runner was probably the last vechile I routinely did that with. I never had deposits on my pistons or anything like that and my Cat was so clean that When I took it off to put a new cat back exhast on it was clean and clear and I could see through it easily!
So ekpolk has is your 2 stroke oil in the fuel working out on your Toyota? Seeing anything odd in the UOA? Getting any real results with fuel economy?
I had some serious boost pressure going on in my 1986 4runner and the addition of upper cylinder lube significantly reduced wear and tear on the valve stems,valve guides and the ring pack. I used to use Amsoil 100 to 1 synthetic 2 stroke oil. A few times I had to use GOld SPectro from local bike shop when I ran out.I also found that my fuel injectors which where not the OEM type but where rotating disk type instead of pintel type where drastically quieter when the 2 stroke lube was in the fuel! When I ran that off road as my play toy I ran nothing but 120 octane fuel in it and 16 psi of boost on top of 10to1 pistons with an intercooler.
