Cliff Parvin, Even this is better for your motor than no oil.

What a lot of people have no idea is bar and chain oil is actually higher quality oil. The tolerances on a chain saw have to be extremely tight.. I mean think about it. If they were loose the chain would come off and kill someone. So this oil at ~5.90 is actually better than the ~$30 repsol. They just can't get ppl to pay what it's worth so they sell it cheap.
