Gearbox Oil
I'm sure I bought 90 oil when I last changed the gearbox oil but can't find any now. These are the only oils I can find - is one of them OK?

Re: Gearbox Oil
Recommend you get a gear oil that states that it is safe for use with soft metals such as brass or copper. Tractor supply has a product that states very specifically that it is for use with vintage Ford tractor gearboxes.
Your MUTT's transmission is constructed using plenty of those soft metals. So, you don't want to use a product that breaks those metals down.

Re: Gearbox Oil
The 80W-90 would be the best choice. It is a GL-5 oil but I see it also has the MT-1 additive so it should be Ok for the transmissions syncros. The other oil is a bit on the light side.

Re: Gearbox Oil
Thanks for the replies. Yeah, lately we have been in the high 30s, low 40s so oil too thin could be a problem.
With the smaller market here, finding specialist oils it a bit difficult but I will keep searching to see if there is anything more suitable but I do need to change it soon as I need to replace the leaking sump plug.

Re: Gearbox Oil
Sounds good, we can get 80-140w over here, I live in the south where it is warm, thought it might help with some of the drips.
Re: Gearbox Oil
Howard, This is exactly what was specified for the original specs so this would be perfect. The only advantages of the newer oils is the newer additives and I really don't think that is a concern since you are not racing nor are you really abusing the vehicle.kmam wrote:Found this from Penrite - does it sound like the good oil?:

Re: Gearbox Oil
Isn't it nice to know you're on the right forum? All the help anyone could ever want is right here.
Re: Gearbox Oil
I just love when the "experts" chime in. The MT-1 is added to the oil to make it usable with yellow metals. Now, If it was still no good for that purpose don't you think the lawyers would be advertising all over TV wanting to start class action suits against the oil companies? I am pretty sure the oil companies know that and they have tested the oils first to prevent that. The original GL-5 is what started the yellow metal debate and you know that once one bad thing hits the net it blows up. I was hoping Raymond would get in on this since he is in the oil business and has all the proper degrees to explain the additives, as he has done in the past. But Howard, go with the GL-1 and then you know for sure you are safe.

Re: Gearbox Oil
Thanks again all. I have ordered the SAE 90 for vintage vehicles. A little dear but given the money I have spent on this MUTT it is worth it.

Re: Gearbox Oil
Just remember that GL1 through GL3 are obsolete and that API does not test for compliance with these specs anymore. So buyer beware.
My advise is still to use GL4 which should always be safe, or GL5 with the MT1 spec. GL4 should always be safe for manual transmissions. If in doubt, call the manufacturer. They don't want you using the wrong oil and then going on the web and telling people it damaged your equipment. And GL5 oil will not immediately destroy your transmission. What happens is that the high pressure additives contain active sulfur compounds. These sulfur compounds are slightly acidic in nature. They essentially wear away non ferrous metals one atomic layer at a time. So your synchronizers won't go bad overnight, but their useful life will be greatly shortened. The MT1 additive buffers the acidic effects of the sulfur high pressure additives. For the best protection ask about Mil spec 2105E or it's civilian equivalent SAE J2360. Again, if in doubt, call the manufacturer. Most packages have contact info, and if not, google is your friend.

Re: Gearbox Oil
Thanks Raymond. I have ordered the 90 already and I am guessing that Penrite is reliable enough to ensure that the oil they make for vintage/historic vehicles is up to spec. In future I will order the oil you suggest and save a few dollars (plus it is available off the shelf instead of a special order).
