Re: When 2-stroke fuel is mixed, does it stay mixed?
The reason I posted this question originally was because of an experience I had breaking in a new 40HP Merc this summer. The Merc's oil-injected, but the breakin recommendation was that fuel be premixed at 50:1 for the first 10 hours or so to make sure oil injection was working and to provide extra oil for new, tight fitting parts.<br /><br />I mixed as Backfire recommends. Dumped enough 2-stroke oil (Quicksilver Premium Plus) in an empty gas can for 5 gallons of 50:1 and added 5 gallons of mid-grade gas from the pump. Shook the can up for good measure and dumped it in the nearly empty built in tank in the boat. Did the same thing a second time, giving me 10 gallons in the built in tank.<br /><br />Didn't get a chance to run the motor for the next 2 or 3 weeks. When I finally got out with it, I had a heckuva time keeping it running for the first half hour....and blue smoke was everywhere. I practically buried the launch ramp under a blue fog. Gradually, as the smoke died down, keeping the engine running became less of a problem. The engine's been a good starter and runner ever since....but I've not added anymore premix to the built in tank.<br /><br />Draw your own conclusions.<br />Bob
