Bar / Chain Oil

[Witterings]

Is there any real difference between the Bar / Chain oils and mineral vs semi-synthetic, I was just about to pull the trigger on some husky mineral oil (the cheapest) and then saw the link for Stihl SynthPlus which reads "to prevent resinification during prolonged downtimes"

 

Is there actually much of a difference, it's only a few quid more for 5 ltrs, I'm an occasional user so it will have prolonged downtimes and if it helps reduce maintenance cost I'm all in .... if it doesn't make any difference I may as well just get the cheap stuff.

Wash yr tanks out if yr not using fr a while. I put a bit of red deisel in my chain oil in Winter, unless its Site of Special Scientific Interest. Which thins it a bit,   10% or so. K

Yes, Synthplus doesn't turn to goop when it's cold so no need for faffing with thinning it any time of year and I've never had to flush to prevent resinification.

We've had this question before, my bars run on it and last well but it's difficult to compare longevity as they last so flipping long. In theory better lubrication means less energy lost to friction so more for cutting, I suspect much less of an effect than a sharp chain.

Other tip is Synthplus is 17% cheaper if you buy 4 of the 5litre from L&S Engineers.
