    Hey Guys,
    I have a 21" Gold series LAWN-BOY and have been using STIHL 50:1 oil. I was wondering if I should only be using 32:1 LAWN-BOY oil because thats what it says on the cap and thats what the LAWN-BOY dealer said. Is STIHL oil good enough or is there a certain type of oil thats the best for my mower?
    Allso what oil might be the best to use in my shindaiwa and STIHL trimmers?

    You need to use the correct ratio of oil/gas for the particular machine. Trimmers or 2-cycle mower may be 40:1, blowers may be 50:1, Lawn-boy is probably 32:1. If you are not using enough oil in the gas, that's like running a 4 stroke with not enough oil in it, or vice-versa (too much oil will make it smoke very bad). I use 40:1, even for 50:1(a little more oil is better than not enough).

    yup, don't put any guess work into the ratio. Actually measurement it out. In the past when I first started out I would just eye ball the color..big mistake..lost 3 trimmers in 2 years. I finally learned though.
