    I saw a 2 cycle oil today - "Pro" something or other. It claimed that it was a special oil that could be used in 50:1, 40:1, and 32:1 engines.

    It literally claimed that one mix (i.e. dump contents in 2.5 gallons of gas) could be safely used for all three mix ratios.

    Is this true?
    Would you recommend it?

    I would like to get away from separate gas cans for my different 2 cycle equipment, but don't want to damage the equipment.

    i do the same thing with echo ,stihl or husquevarna mix.
    no matter what machine its 50-1 .no problems,no fouled plugs,no dirty exhaust ports.i do use 90 or above gas.

    Myself and a lot of people here use Amsoil (www.amsoil.com) synthetic 2 stroke oil. You just dump a 8 oz bottle into a 5 gallon can of gas and go with it. It eliminates those pesky clogged spark arrestors and exhaust ports. It also reduces the need to change the spark plug so often.

    I would have to agree with Richard, I was interested in this type of oil last summer, and the subject came up. I read all the posts on this subject. I ordered some amsoil for my 2 cycle equiptment, and started using the oil. What a difference it made, the equiptment seemed to run better, and the best part, no fouled plugs or clogged exaust ports. :D
  5. I think it was on the Amsoil web site I read that the percentage of mix is determined by the oil not the motor.

    So if it's a modern 2 cycle engine, it'll be OK with 100/1 mix.

    A lot of people complain about Stihls being hard to start.
    I have nothing but Stihl everything. (it's what my dealer sells)
    All have Amsoil at 80/1 mix and all are easy to start.
    Even with last year's plugs and last year's gas!
    Even the BR400 backpack blower which doesn't have a priming bulb!

    I use a John Deere brand oil mix that I bought at Home Depot and it work fine. I used it all last season and had no problems. Although, Amsoil has a reputation for being a suberb product.

    I agree with everyone regarding the synthetic 2 stroke oil. I just switched over to a synthetic brand that my dealer here in Canada got. It's not Amsoil but some other brand. All my 2 cycle equipment seems to start easier, run stronger and is more fuel efficient now.
  8. amsoil 2 cycle is great we buy it direct from amsoil by the case .
    We use all amsoil in everything 2 cycle, truck oil, ztr engines.
    Its a great product.

    Everything I own gets 50:1 synthec. I ususally buy the stuff labelled "Marine" in the 1 gallon or even 5 quart containers.

    My equipment is Redmax, Stihl, Husqvarna, Crapsman hand blower and John Deere stick edger. Never any trouble, same redmax machines for 6 years now.

    I used to have trouble with 32:1 fouling plugs and exhuast.

    I realize that you have not had any problems with the marine 2 stroke, but I have been cautioned against it. A marine engine is water cooled and runs at a lower temp than a backpack or trimmer. I was told by the Echo rep that marine 2 stroke should not be used and may lead to seizing. I also had a few bottle of Bel-Ray MC-1 for 2 stroke dirt bikes that he said should not be used because of the temp differences.
