Thread: which 50-60cc Stihl chainsaw

Have noticed the dye colour fading in older fuel but it is usually very old fuel so petrol has gone of anyway. We don’t take any risk. Dump fuel, at a cost of $3+ per litre, and refill with fresh stuff. We have to be mindful that it doesn’t take too much w/shop time for repair cost to be worth more than saw is worth in some cases.
If the fuel has been mixed for a month use it in your lawn mower, safer that way especially for the bigger saws. I know people use older fuel but personally I replace after about a month on my 4x saws. I hate the prospect of working on my own gear unnecessarily.

Yeah, I chuck it through the ride on mower blended out with straight fuel to get the oil amount down. The mower doesn't seem to mind even older fuel like that, worth noting though that most good two stroke oils contain a stabiliser component nowadays and if you are using 98 or 96 (non-ethanol) grades to start with the fuel should stay usable for a lot longer than a month before it goes pear shaped on you. I swap out the fire brigade stuff every 6 months or so and so far this has completely ended all of the stale fuel issues that we historically had.
