In general, it’s OK to add 2 stroke oil to diesel fuel for extra lubricity, but it’s far easier and more effective to use a fuel additive.
As my friends and family will attest, I have a wide range of interests, but small-engine repair has never been a hobby of mine. Nevertheless, because I own a little property, I’ve had to own all the basic equipment necessary to maintain it, from chainsaws to lawnmowers and snowblowers to string trimmers.
