I use Mobil 1 10W30 in everything 4 stroke. It is not only a better lubricant but definitely reduces friction which makes engines run smoother. Purchase it through walmarts online and pick it up at the store.
I use Lucas's Top engine oil to lubricate upper cylinder and it provides a better running,smoother acceleration and less friction.
Am currently considering 5W30 but a little hesitant.
Nice to know which synthetic for 2 stroke engines as I am starting to service some of them. Curious about upper cylinder lube on 2 strokes that mix in the carb, there is no protection or lubricant through the fuel system until it mixes-- any thoughts about using the Lucas in the fuel?
