    I have allot of TCW-3 50:1 gas mixed (2.66 oz per gallon) that I am not going to use this year
    My leaf blower takes 2 cycle 40:1 (3.20 oz per gallon)
    I was planning on adding .54 oz of normal 2 cycle to a gallon of TCW-3 50:1 gas mix and use that mixture in the leaf blower
    That would make it 40:1
    But of course-it would be two different kinds of 2 cycle oil
    What are your thoughts beside going boating more

    my understanding is that the “w” in TCW stands for water cooled engine use as these tend to run cooler that the air cooled engines like chainsaws, leafblowers, weedwackers it is not recomended to use. So I would say proceed at you own risk.

    Put some marine Stabil in the gas and use it next summer. Been doing that for years with no issues.

    I’ve been running TCW-3 in my fleet of Lawnboy two-stroke mowers for more than 40 years. Not one power head failure or even plug fouling. Funny, I have BOUGHT a few that came with a fouled plug and the PO was using the Lawnboy air-cooled oil!!

    Long live American manufacturing!

    I had a bunch of it left over one year. I burned it off in my Craftsman lawn tractor at about 100:1. Of course, the tractor is a 4 stroke and the plug did foul after awhile. I changed the plug and thereafter added Seafoam to the mix. That stopped the fouling. It was a little smokey, but ran fine. That was several years ago and I’m still using the tractor…

    I have been doing it for nearly 25 years in trimmers, chain saws, and blowers and had no problems whatsoever.

    I’m with Frank and Tubs. I run TCW in all of my 2 strokes and have not fouled a plug in 20 plus years. I thought (dangerous, I know) that I read once that TCW has a lower ash residue, due to the lower burn off temps of outboards. My “logic” is the oil is needed in the crankcase, which is generally cooler than the cylinder. Its the burn off that differs. My Riobi weed wacker has the same plug it came with 12 or so years ago, still fires up fine. Three years ago I finally treated my old Toro snowblower to a new plug. Not much difference, but it deserved it after the 33 years of service it gave me so far. Oh, I have been using synthetic for the last 10 or so years, but notice its getting harder to find unless I get $$$ oil. Anyone use semi syn with similar results?

    If you have too many, AND not enough, you're a collector.

    In all fairness, the “logic” is only half valid. The hottest part of the engine is at the exhaust ports, and that is where most of the wear occurs. It’s sort of a battle. The oil must provide cylinder lubrication, but in a perfect world it would burn off before being discharged into the water we drink and air we breathe. Solve that problem and get rich. Oh yeah, burn off with no smoke or smog also.

    My last purchase of weed eater 2 stroke oil is Valvoline with the TCW3 designation on the label. Lists all types of water and air cooled applications on it. Got it from NAPA. Previous oil was labeled for air cooled engines no TCW3 mentioned on it. And another observation on gasoline. Casey’s General Store is now selling 91 octane gasoline without ethanol. Found it at a local one I’ve never been to.
