Help, I ride a Honda Vt250 Spada and today I put 2 stroke engine oil into it. I believe that my bike is a 4 stroke bike, is this bad or really bad. ???????
Two stroke oil is thinner and could cause damage to main bearings so I would be changing it. I would suggest Silkolene Comp 4 10w 40 weight. It is not the cheapest oil but it is very good.
