This old troy horse tiller I have apart I would love to refill with some 140 Gl-1 oil or 80w140 but from all the checking and calls I have made it no longer exists up my way any more
All I have found is some Lucus syn motor cycle oil 80w140 that apparently is gl-1 but it is like 25.00 a liter which is way too much for this old girl considering she will need at least 4 maybe 5

I talked to my uncle about it who was a real good CAT mechanic for over 45 years and he tells me oils have changed big time over the years as we all know and today's gl-5 will only be an issue in these old tillers and the brass if the temp gets high like over 200 degree which it won't

So?? have you guys heard this before?? or what other options do I have
Do some gl-5's state they are OK with brass??
Thanks for the feedback

Check the Warren oil site and see if they have a seller near you.
Thanks for the link, I am no further ahead

I did find some Lucus product that may work but I am waiting to hear back
The spec sheets says ideal for older wrom gearboxes so maybe it might be OK
It is 85W140 plus
I would think it would be OK. It mentions older worm gearboxes. Really the best bet for any of the new multi-vis oils if it does not say "yellow metal friendly" would be email the company and get the info directly from the manufacturer. This has long been a debate and mostly lots of heresay. As one of our local newscasters says, educate yourself, get the facts.

Here is what Troy-Bilt says: Gear Oil
Snow? We just had a week here with 3 or 4 days in the 70's.
That is what I put in my Troy-Bilt Horse. Not that particular brand but GL-1 SAE 140.
There was much ado about the newer oils and "yellow metals". I once saw an article (wish I would have kept it) claiming the yellow metals issue was not so much a problem unless the unit was running at temps in the 250 degress and above. So if you have a 90 or 140 weight gear oil I would think you will be fine. It's not like we run these tillers 24/7. Still think it's terrible trade between the US & Canada is not better!
