Re: Type of oil and additive?
If the motor doesn't use oil you don't need additives or High Mileage oils. The High Mileage oils have additives intended to swell seals and generally reduce oil consumption. But for a motor which doesn't use oil they may actually do more harm than good. Oil and filters depend on your budget. I always use full synthetic. But non synthetic is quite less money. Your choice..and if the motor does use oil you may want to try the High Mileage oils. I'm thinking though that if everybody used full synthetic oil we would collectively import less oil from countries that aren't really friends of ours.
