</font><font color="blue" class="small">( i have a stihl fs 80r trimmer and i have all stihl chain saws so its simple to mix one can of fuel and use all. )</font>
This point has got me to wondering about two questions.
1) I've heard in the past that each manufacturer's 2-stroke oil is engineered for their own cylinder heads and other parts. Therefore it's best to use Stihl oil in a Stihl machine, Husky oil in a Husky, etc. Right now, the only 2-strokes I own are the Stihl 036 and a little Olympic (i.e.-Oleo-Mac - an obscure Italian brand that I hope never breaks because I may never find parts for it...) arborist saw, so I buy Stihl oil. The Olympic has run fine with it so far, though I've only got 25 or 30 hours on it.
For this reason, should I stick with Stihl for the next string trimmer? Any red flags out there from people who used Stihl oil in an Echo string trimmer with bad results?
OK, and question #2:
Last time I brought the chains for my Stihl 036 in to get sharpened, I started talking to the guys there - both sales and service techs. Both said that the 4-mix engines are holding up well, but I am still skeptical. Since I'm in the market for a larger trimmer/brushcutter, I was looking at their 110's (a 4-mix) and 250's (still 2-stroke). Although the 250 is probably more machine than I need, I may go for it (one salesperson at another place had told me that the 036 was more than I needed, but I have absolutely no regrets). My question is has anyone used a 110, and how is it going? Anyone used a 250 too? Thanks,
