    I just bought a stihl ms 362 saw. The shop gave me stihl synthetic 2 stroke oil. I use regular stihl two stroke oil in all my other stihl equipment mixed at 50:1 . Are the new saws designed to use synthetic or should I just stick with the regular stihl two stroke oil? I've heard you should not break in a saw with synthetic oil ? I also heard after running synthetic oil in a saw that you should not run any other normal two stroke oil in it. If anyone knows any info would be greatly appreciated. Thanks Dave

    Most of what you've been told is bs. You can run the orange bottle and be fine or use the synthetic and it will be better. The saw will break in fine on synt and you can switch back and forth without an issue, but I have a feeling you'll try the good stuff and stick with it.

    I, too, favor the new Stihl HP Ultra synthetic. Runs cleaner and has stabilizer built in. Your muffler screen is less likely to clog with synthetic also. Synthetic 2-cycle oil is like synthetic 4-strike oil - engineered for the application from the ground up. Dino oil was adapted to the application; it works, but not as well. I like Husky's synthetic also, but am now using the Stihl HP Ultra full time, in all my saws, and all at 40 - 50:1, even my old Shinny's designed for 25:1. No problems after 3 years on Husky synthetic.

    I just saw a huge testimonial for the orange bottle Stihl oil. I had a 066 here to port that had a lot of run time on it. It was obvious by how dirty the saw was under the covers. The saw had been taken care of, but it was obvious it had seen a lot of use. The thing of it was, the topend was in excellent condition with almost no wear. The only wear I saw at all was on the intake side of the piston. The ring end gap was still like new. There was no carbon buildup in the exhaust port. What little was on the crown and combustion chamber was soft and came off easily. I was impressed enough that I asked the owner what oil it was. I expected him to say Ultra, only to find out it was the orange bottle oil. I know we all like to give our saws the best we can, but his saw has been well protected.

    Brad, by chance did you ask the owner what ratio oil/gas he ran in his 66?

    I have broken in a MS361, MS441 on Ultra and in the process of breaking in a MS362 and MS660. I won't use anything else, for what these saws cost why use anything but the best. I used the orange bottle Stihl oil for years and had no issues, but when the Ultra came out I switched over.

    I find this very odd as Stihl orange bottle oil is notoriously dirty burning oil, the worst out of the bunch in fact, even my dealer said their oil issues have plummeted since ultra came on the market. I'm thinking they changed the formula at some point, because the 4 mix engines couldn't stomach the stuff at all, that or they were really just running what the dealer had on the shelf, aka ultra lol.

    I agree with Andyshine
    When people talk about " breacking in a motor " with synthetic they mean 4- stroke crankcase oil NOT pre mix. no you shouldn't on A 4 STROKER .....
