Just started using Millers GL4 spec, seems good so far on a rebuilt 4L1 motor. However this is such a subjective / emotive subject you will be inundated with others that will have differing opinions - then make your choice!

I'm with bezzer on this one. I used a GL4 spec 75/80 gear oil. GL4 is wet clutch compatible. Gear oils are classified differently to engine oils. The 75/80 is approx the same 'weight' as a 10/40 engine oil.

The Haynes manual for my 4LO states 10W/30 engine oil,.....I wonder if they would suggest anything different if the LC had been invented today.

Have used Yamalube and quickly removed it. ATF has long term issues with non BBearinged spining bits. Your bike.. your choice.

What grade is the best to use? 75/80 in my case, just make sure it’s GL4 spec or higher.

Isn't Silkoline Light Gear Oil still to go to? Blimey, used that 30 years ago and was supposedly the best oil around then. Is there nothing 'better' after all this time? By 'better', I suppose I mean slick gear changes and excellent protection against wear (although how anyone would know this is very difficult to say).

I doubt oil companies would spend the money on development testing oils for small capacity two strokes anymore. There can’t be enough demand for it, most motocrossers are 4 strokes now. Probably why the ‘best stuff’ years ago, is still the ‘best stuff’ now!, imho of course.

The best gear changes I had was with the 75/80 oil.

I use Lucas 80/90 in all my two stroke gearboxes for years and thousands of hard street miles with excellent results.

Surprised that even this arena has sunk to 'oil wars' Usually it's confined to the Crap cars (where the meanest, most worthless, pile of Shite.. recently aquired tho) Clearly demands THE most esoteric/pricey/heavily advertised oils. Because it will make the POS perform better than new.. as if.

.... wondering if there is a favourite. ...everyone has a favourite oil and will put a case forward for it! Oil and fuel threads are always a great(and regular) debate here! While I do get a specific gear oil, my favourite is the one I can pick up off the shelf easily, in all honesty, the boxes dont seem to be that fussy, I just change it once a year ...We certainly chucked what ever was around in them back in the day and I dont remember anyone changing it unless it was in bits anyway!

Which one is most likely to be in the stores/on the shelf around your way then? Generally I avoid Halfords for anything if I can, sadly they have put a lot of little shops out of business a long time ago.

Which one is most likely to be in the stores/on the shelf around your way then? Generally I avoid Halfords for anything if I can, sadly they have put a lot of little shops out of business a long time ago. I’m going to be using this in my budget YPVS: www.wilko.com/car-maintenance-products/comma-gear-oil-ep80w-90-gl4-1l/invt/0077164As bare says snobbery using the most expensive oil (possibly on a clapped out engine) is not going to make it brand new. The oil grade standards have improved over the years, and even a budget oil (like this) is better than some from the past. Cheap enough to change regularly (which is probably more important). Available off the shelf easily across the country. Jon

Jon, I would be wary of using any EP oil in a bike that uses the gearbox oil to lube the clutch. As I understand it they are formulated for the Extreme Pressures between gears and will cause incurable clutch slip. This lore dates back to my British bike days and things may of course have changed. If not, most economy engine oils will be ok, my valve has done 45k miles in my ownership without dedicated gear oil and I've never had any box or clutch problems. Yamaha boxes are well made and robust.

Most usually Halfords Light gear oil or if I have some left over 10/40 from the 4 strokes and there's enough of it, ill use that.

Light Gear Oil worked great in my KTM200EXC, happy to go that route with the YPVS too.
