Cant say for sure, but seems like the Walmart oil does help mine. Didn't start adding anything until this last fall at about 100k after I had some injector issues. I have tried PS Diesel Kleen, Howes, Walmart 2 Stroke, and Optilube. Have not had injector or filter issues when running a lube about 12k miles. May be a little smoother and quiet idling. Optilube among other lubes were involved in a test you can search for. I know I have added a link a couple times on this forum. Bottom line, I will run some kind of lube on a regular basis from now on.
