Hmmm,
25 hours @ 10? gal/hour = 250gallons of gas burned * 2 oz/gal of 2-cycle oil
= 500 oz = 3.9 gallons of 2-cycle oil in the gas of a rotary.  4 gallons of
2-cycle oil at WalMart = ~$24.

I remember Tracy Crook once wrote (newsletter) that he has asked doubters who
voice opinions that mixing oil with gas is not desirable "If you had an
additive that you could add to your gas that would prevent stuck valves --
would you use it".

Sounds like people do put additives in the oil, and the cost is roughly
comparable.
