O
I know this has been discussed a bit, but I think the fact that there seems to be two very different views on this is interesting. Let me start the debate by raising a few questions.
First many say adding oil to the gas leans out the burn, why do you think that? Why would sled manufactures add oil to new sleds gas tanks for the initial break in period. If the oil causes a lean condition, would it be smart for a manufacturer to suggest this on a new tight engine?
Second, most two stroke engines from the very beginning have had oil in the gas, why has that worked so well for so many years? The desired gas to oil ratio is approximately the same whether the engine is injected with oil or if it’s mixed in the gas. And yes I understand that the oil injection is not direct injection, but for the sake of this discussion it shouldn’t matter.
There is also the issue of oiling the bottom end with injection systems, but that’s not what I want this thread to discuss.
What are your thoughts on whether oil added to gas leans out the burn, and if so why is that?
