    Sorry if I missed it somewhere in the several hundred pages of content. Do you find these superior to the oils branded by Stihl and Husky?

    I like Mobil 1 also. . Couple of cases here as well. Is there any chance of Mobil getting back into the U.S. market with 2 stroke oil?

    Have you ran any of the Lucas? If not will you do a test on it. It seems to be real good for the price.

    have some. haven't ran it yet.

    several people including myself have ran it 32:1. Consensus was it was very dry inside for being 32:1. There are better options for the same money. For example the schaeffers 7000 for approx $28 a gallon or schaeffers 9000 for approx $45 a gallon. Another cost effective would be yamalube 2r. All should be run 32:1.

    A very smart person I know said the lube between the piston and cylinder isn't the reason he runs 32:1. What needs the oil is the bearings.

    When Mobil1 2t was taken off the market I actually contacted them about it "I'm sure others did as well" the rep I spoke with said their was no chance of the oil returning. It was a phenomenal oil, It had lots of PIB.

    I still prefer ester oils for a few reasons. K2 is still my overall favorite, it has a good ester backbone with a good amount of PIB. HP2 is a good choice with it's high film strength. For the ultimate oil in extreme use, R50 and Motul 800 are unbeatable.

    I agree it's all about the bottom end keeping the crank seal nice and wet.

    And yes I just replied to an oil thread again.

    MX2T was a carboxyl ester oil. No PIB in its blend.
    It was great stuff. Sad to see it go.

    I ran a similar test with these ratios using multiple saws, both ported and stock, with tunable carbs.
    The stihl ultra will lose power mixed richer because it was formulated to run at 50:1, and it has a lower rating of "FB", so I decided to not use it.
    I picked three different brands of "FD" rated oil off the saw store shelf: Stihl hp super, red armor, and husqvarna xp. I remember similar results to Julian's test at lower rpm's. When I started testing different tunes I noticed 32:1 was providing more power and faster cuts at a higher rpm than 50:1. Higher rpm as in dialing it up as high as can go while still audibly 4 stroking. That rpm level is beyond the limit of an auto tune and the typical work saw, but not for gtg's and racing.

    Anyone try Idemitsu: synthetic blend Racing premix rotary fuel lube...in a saw?

    Neighbor had a race car with a Mazda rotary hotrod motor that he sold. Gave me the extra mix he had.
