I have a 1976 Johnson 35h tiller that I mix synthetic blend in. It has run goofy on full synthetic, and runs better on the real thing, but if the shop only has the blend, that is what it gets. The Lower Unit is full synthetic gear oil and that shows no issues.

Mabe I am looking for trouble though???

I ran blended oil for 8 years in my johnson 90 hp.ran great at trade in,it checked out with no determined loss of compression.Also ran it in my new 115 hp johnson fastrike for 3 years,again without any ill effects. I used pennzoil blended oil.the oil showed much less carbon on the plugs.I also use it still in all my two cycle yard stuff as well as my chainsaw
