Re: oil been sitting for 7 years

Might want to drain/clean/flush your entire fuel system from tank to carbs and everything in between, so when you crank it up you don't suck water/trash/varnish/deposits right into carbs. And maybe run some Outboard motor oil in your first tank of gas until you're dead sure the oil injection system is working.
Good Luck!

although oil generally doesn't deteriorate with age, your tank could easily have accumulated water from condensation, etc. over 7 years. Why chance it; it was free?
Or start with fresh and add the old oil back a little at a time.

The actual oil component may not change much, but the additive package can deteriorate and also separate out and gel.

So yes, drain it and flush the entire fuel system. The suggestion to run pre-mix at first is a good idea too.
