## Questions & Answers

**Q: Good use for dirt bike chain?**
A: Try a chain lube . Unless you want 90wt on your back.

**Q: Is this overkill for a jeep xj's diffs? i ask cause it says heavy duty and shows a semi**
A: The semi I suspect is for show. I used this on my 3/4 ton Ford F-250 because this specific weight was listed on the line order. I would consult your Jeep manual or is you have upgraded diffs and you heavy wheel I would go for it

**Q: i would like to know if the api is GL-4**
A: "Exceeds API GL-4" does not necessarily mean it's safe for "yellow metals".  Valvoline also exceeds GL-4 but doesn't specifically state that it's safe for synchro's.  Is this OK for synchro's or not?

**Q: can this be used for a 50 cc scooter transmission fluid? the owners manual says SAE 90 and nothing else...**
A: I don't think that there would be any problems using it in a lil scooter tranny some folks put it in high powered race cars

### ⭐⭐⭐⭐⭐ Great oil
*by T***3 on January 22, 2026*

All Lucas products I tried so far are great and really do what they say they will. I was using it for my 96’ Harley as transmission oil and I put a lot of miles on the bike. Oil is very thick has the honey like consistency and works great. Protection more than adequate.
