Oil, 10W‑30 Full Synthetic Motor

Full synthetic oil cannot be mixed with a standard, natural, or blended oil. If you'd like to use synthetic in your machine due to high hours, you'll need to drain the old oil, flush the engine with kerosene, flush with synthetic oil, then add the new oil with new filter.

Caution! Synthetic oil is thinner than standard or natural oil, so leaking from oil seals is common. If excessive leaking takes place, a replacement seal may be necessary.
