i was just wondering sumthing while sitting here at work. does the fact that our cars have oil injection lower the a/f ratios? like say if we had no oil injection and tuned our cars to say 11.5:1 a/f. now if we injected the oil, what would that do to it?

my point is, if it lowers it, our cars are ideally tuned with the same amount of fuel as a typical piston engine, but with the oil being factored in, it makes it seem as though we are way more rich than needed. does anyone understand what i'm getting at here?

 

yes it does but the oil is a relatively small amount that it doesnt really matter. there was a thread about premix lowering the octane in the rotary performance section, if you do a search

 

i know it lowers octane, but i'm talking the a/f ratio. by injecting oil, there would theoretically be more fuel in the mix even though it's not all getting burned
