In this thread you'll probably run into a lot of responses from old timers who will tell you to run it at the manufacturers recommendations of 16, 32, 40, and 50:1 depending on the age of your equipment. These people are scared like deer in the headlights and will only put their toes in the water on the lakeside instead of jumping in. It's just like the oil change companies brainwashing you into the 3000 mile oil change interval in your car. Why? Because they make more money if you do what they tell you to do! Lawn-Boy, TORO, Stihl, Husqvarna, Echo, and many others are no different and make a lot of money selling you their branded oils. Once you give in to their cocaine tactics, you're hooked! The fact of the matter is that Amsoil was the first company to produce synthetic oil for 2-stroke engines over 43 years ago. After 43 years, you can bet that they know what they're talking about. Otherwise, they would be out of business. Personally, I run Amsoil Saber at 85:1 in all of my very expensive Stihl chainsaws, leaf blowers and string trimmers. I also use the same 85:1 Saber mix in my Lawn-Boy DuraForce equipped lawn mower. None of this equipment has any issues whatsoever except better performance, extended spark plug life, no smoke or carbon buildup and very low maintenance / operating costs. Best of all is one mix covers them all! Take the plunge, you won't be disappointed! Don't be a scaredy cat!Hi everybody I have some questions for you. I have run amsoil 100:1 saber mixed at 100:1 ratio in my current echo stuff, toro with suzuki 2 cycle engines with no problem what so ever and burn very clean. I know the lawn boys recomend 32:1 as they have for years and use that old ashless oil from the stone age.
Does anybody are can you run amsoil at 100:1 in a lawnboy 10550 duraforce engine and be safe as far as lubrication is concerned.
Do some of the die hard lawn boy guys play it safe at 80:1 or richer??
Any feedback imaginable would be great as far as tid bids on what makes theses things run great for a long time and keep carbon build up to a minimum.
I also saw that the spark plug uses a bpmr4A at a .035 gap which it says in the book but that is HUGE. Is this common i guess.
It starts and runs good and has the slightest surge to it at fast idle and you can hear it surge when on slow rpm. RPM is at 3200 and change as I checked it with a snap on digital tach.
