Also the dopes in the 2 stroke oil can form deposits in the injectors

I'm saying what myself and millions around the world use and we find the effect beneficial.
I've never seen any data to show an improvement but the increase in smoothness is without question in my experience and my car still returns 44 mpg around town.

If my injectors aren't gummed up at 209k miles, they're unlikely to be any time soon so I'll just carry on.
A lot of the things people do on this forum won't be supported by the official sources so everyone should of course make their own decision.
