    I just use the Stihl Ultra at 40:1. Just use the 2.5 gallon Ultra bottle in 2 gallons of gas. No thinking for me that way. When we are going to be cutting heavy, I have a 6 gallon jug that I put three of the 2.5 gallon oil bottles into.

    Thats real simple! I used to do the same thing, but got tired of buying the expensive stuff and the smell kills my sinus's. I mix mine with a ratio right and use either K2 or H1R at 32:1 now

    It only takes me 5 gallons total to cut the 30 cords of wood I need a year. I might use another 2 or 3 through the year cutting other stuff. Oil expense is a non-issue for me. If I ran a logging outfit or tree service, I might be more concerned. :D

    I remember an Oil thread awhile back that said Woodlnd Pro and Poulan Pro, which is Husqvarna oil, was put out by Spectrum! When I can't get the Amsoil Saber, from my dealer, and need oil right away I use the Poulan Pro synthetic oil.

    I had way too much time on my hands a few days ago and wanted to look into what manufacturers recommended in terms of ratios when there were no EPA restrictions. It is frequently said around here that 50:1 is an EPA thing, which seems reasonable.
    I looked up 390xp owners manuals for several different countries including Sweden (hard to read) UK, and Australia. For each region the recommended ratio was 50:1 using full synthetic and 33:1 for dino. Stihl seems to have one manual with many languages, but was also 50:1 synthetic.
    So assuming that the manufacturers are not recommending this ratio because they know the saws will explode, resulting in more sales, their engineers are comfortable with 50:1 synthetic. I'd bet a stock saw fed with good oil and fresh gas at 50:1 is just fine. 210 PSI and 15000 rpm prolly a different story

    I used 50:1 for years with no problems at all.

    It was when I start running ported saws that I change to 32:1 or 40:1.

    To clarify, I've got nothing against Amsoil, just the very lean 100:1 or 80:1 mix ratios.

    Anyway, quoting from the above link:


    About 100:1 Premix Oils - Since the 70’s there have been repeated advertising claims made by various oil brands claiming that their oils can offer suitable lubrication for competition two-stokes on a 100:1 or 80:1 premix. In many cases, these claims are “supported” by testimonials from various users. Despite the oil makers claims, and the sincerity of the testimonials … it’s not so. Running a 100:1 premix would be much like running only 2 quarts of oil in your truck, expecting that the quality of the oil can make up for the quantity …. It cannot….. no matter how good the film strength is “claimed” to be. The truth is, many two-stroke engines can “operate” on a 100:1 pre-mix so long as rpms are kept very low (as might be the case on a novice class open bike). But the first time that 100:1 engine makes an extended higher rpm run … it will lose the mathematics of oil migration, and score a piston. There is just no way around the math.

    50:1 orange bottle Stihl /2gallons for break in. After that, any good synthetic at 50:1

    All your saws will grenade with this advice......I don't know ****....I just cut timber with ported saws for a living....:laugh:

    This is somewhat off topic, and sounds counterintuitive, but even though they run their saws all day long, I'd bet the pro users could get by with less oil than guys like me. I've never seen Sam cut, but when you watch a video by Bitzer, or tramp bushler or Gologit for example, their saws cut "easy". There's none of the bogging, sawdust spitting nonsense you see from me. Good technique, a true bar, and a perfect chain will put much less stress on a saw.

    And a savvy operator knows when to stop pushing a saw before it seizes up!

    Couldn't the same statement be said about 50:1? It's 32:1 for me from now on.

    Right now 42 to one seems to be the way to go with synthetic oil for me. Why because it is more oil than the EPA 50 to 1 and it is less than 32 to 1 which is to much smoke to breath in if you ask me. The saws I run are all in great shape.

    That's another question I have. We say 50:1 is an EPA thing, and I have said it many times as I have seen it here so much, but there is no EPA in Colombia. And Husky says 50:1 synthetic for its saws sold in Colombia. Is the US market so large that they engineer everything to met regs here and just sell the same stuff the world over, or do they feel that 50:1 is the way to go with synthetic oil? I don't know the answer. 40 years ago we'd think 32:1 was crazy, and we'd be running 16:1 or 12:1

    Well I remember them old Homelite's I think if I can remember was running 8 OZ per gallon!!!!!n Not to good to breath that stuff you know. People get so wrapped up in their saws I really don't understand why they don't take all the smoke they are breathing into consideration? That's why I run synthetic over petroleum less smoke! Less smoke you live better and longer think about that a while.Milling really gets you fumed out. You need to find the perfect balance between you and the saw. Hey do you guys running new strato saws find less fumes?
