God morning all!

so plan on changing some oils around the beast.

Done some research and come up with this
https://www.eurocarparts.com/ecp/p/...nual-transmission-fluids/?522776051&0&cc5_868

Iv read that the correct one is GL-4 and this is what iv come up with, can anyone confirm if its ok?

I recently changed mine, and used this:

https://www.ebay.co.uk/itm/EP90-Hyp...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

What you have listed there is probably OK for an LT77, but could be a bit modern and thin for a series gearbox. Though I am in no way an expert when it comes to gear oils, I just put in what it says in the Haynes manual!

Any GL4 90 grade oil is OK for a series box. Good for swivels/steering box and steering relay to. Also OK for the front and rear diffs.
Avoid the GL5 grade as it is supposed to harm any bronze bushes in the transmission.

Buy a gallon of GL4 90 and you will get through it. Get one of the pump things too, they come with a bottle but I've just found that the pump fits the top of the 5l container, wish I'd noticed that before I poured a litre if oil into it! Makes topping up so much eaiser that I'm now inlcined to do it a lot more often. I paid £15 at an auto jumble

You either do not drive it enough or it does not leak enough for that to last you a several years

I'm finding a very clear "more use = less leaks" rule. Not clear why, perhaps its keeping all the seals moist. I too use a top up thingy, makee the job a lot easier.

Keeps the oil going round instead of sitting in the bottom of the box, warms up the seals so they are more flexible, and prevents the feather edges of the seals sticking on the shafts, and getting torn on restart.

Machinery likes to be used. In 40 years of working on it, I have seen many more problems caused by underuse than by overuse.

Gl4 for the series as GL5 can damage bronze components.
