Old saw oil mix

[Robert Raven]

Ive read that some people think that because modern 2 stroke oil is so much better than it used to be, it's ok to run older saws on 50:1, even if they were originally supposed to run with a richer mix.

 

I have a Stihl 070, pushing 40 years old. I normally use 25:1 as per the manual, but I'd love to use 50:1 or even Aspen when milling. Has anyone done this, do you think it would be ok, or is it a recipe for disaster?

 

Thanks.

These saws were manufacturerd in the day where oil technology wasn't as good as it is now. The mix is dictated by the oil and not the saw, 50:1 is fine.

As Spud says, 50:1...... but only if the oil is designed to run at 50:1. keep clear of cheap, unknown brands, some are little better than the old oils.

 

Aspen will be fine too, as it uses high quality, fully synthetic oil.

Thanks guys, good to know. Think the same goes for my cheap strimmer?

Just been milling all day with Aspen in the 070, no probs with the saw and so much nicer for me. Thanks for clearing that up for me.
