Owner's manual calls for SAE-90. I use SAE 80W-90 purchased at local Tractor Supply.

Here we go! :lol: (That's one of the couple of questions that gets everybody weighing in, all with different opinions and levels of "expertise", "experiences", and "proven data" that they swear by. You'll get comments covering the range of possibilities from "I've used my wife's leftover bacon drippings for 42 years and have never had a single issue with the transmission" to " I found this super secret NASA additive that I put in my synthetic lubricant emulsion and it makes shifting 12.7 times easier and haven't heard a single noise, whine or growl out of the transmission since I switched.)

If it's oily and has a 90W on the container dump in 3-1/2 pints and move on, you'll be fine.

Scrivet--yeah, I didn't think about that until I read your post. The "what type of oil do I use" question is much like the "what kind of paint should I use" question isn't it? Does make for some interesting reading though.

wjw777--since you just joined this month, you haven't had the experience of reading all those older posts we're talking about. Don't worry. If you have the Owner's Manual, just follow it best you can. It's been giving the right information about these little tractors for 68 years now. If you don't have a Manual, download a PDF version of it by accessing the link "PDF Manuals" or "Rudi's Manuals" from across the top of the screen.

...not too sure about using bacon grease in a Cub 'cause it would make me hungry whenever I used it. :lol:

My transmission was quite noisy (believe it was the reverse idler) so I added some Lucas stabilizer (25-33% total capacity) to the 80W90. It's made a world of difference with smoother shifts and less noise.

Everybody knows "what paint to use" depends on whether or not you have converted your Cub to 12 volts and whether or not you are using electronic ignition. :roll: :lol:

Everyone will have a preference...but basically, its all just dinosaur poop :)

I doubt there is an oil out there today that will wreck your Cub, as long as its the right type.
Follow the manual - best advice always.

The manual says 90w up until Hytran was developed in the early 60's and from that point forward the manuals recommended Hytran. In the early 60's they recommended either or. By the 70's it was only Hytran and not using it would void the warranty. Hytran has superior water retention properties, which is a plus since water accumulating in the transmission is a known problem in Cubs.

The what kind of oil should I use question is more akin to the Ford vs. Chevy vs. Dodge debate.

Shouldn't be- that's what Factory specifications are for.

Bob got me thinking...on my 61 Cub I've been paying for all my parts. Never even thought to ask, I wonder if my warranty is still good ?

Gotta have the original receipt for proof of purchase. :lol:
