Another J20C Fluid Thread, What's Good At WalMArt

[t44e6]

Looking for a J20C fluid for a YM336D that is available locally, which realistically for me means Walmart unless I want to drive. I am going to list the brands they sell and would like input as to what if any brands are good to go.

WalMart Transmission Hydraulic Fluid

In no particular order:
Starfire Premium
SuperTech
Lucas Universal
Mobil Delvac 424
Schaeffer Super simplex
Valvoline VV710
Lube King (Warren?)
JD Hy-Gard
Warren

Guessing that Warren is lower end, SuperTech might be made by Warren. Strarfire sounds sketchy. The products from Mobil, JD, Valvoline and Shaeffer's are likely high quality with a good additive package. Lucas could be good or bad.

I appreciate any input on these brands. I am nor worried about the price, but if I can save a few bucks and get quality that i all the better.

I use Schaeffer almost exclusively but i stick with Hygard on the tractors. I run almost all JD equipment and don’t see the benefit to a cheaper fluid. I helped rebuild a JD 6200 transmission that had delaminated friction plates from improper fluid twice. Took two failures for the owner to switch to Hygard with no issues since.

I’m with @Creekside. Owning Chrysler vehicles for 20+ years now I stick with the OEM recommended fluid for transmissions. Engines aren’t nearly as fussy IMO.

Just my $0.02

The only one you mentioned from the big 3 is JD, so I’d get that.

Getting the Hy-Gard.

Getting the Hy-Gard.

I don’t think you’ll regret that. It’s good oil and the OEM oil, so good choice.

Just my $0.02

Presuming this is what you have ...

That's an old tractor, made from 1980-91.
- it's not under warranty by any means
- it was made at a time when fluids back then were not nearly as good as today's, so anything current which meets the specs will be more than sufficient
- nothing from Yanmar is finicky in regard to fluids from that era
- it's not HST; it's a ol' powershift trans

Get the least expensive product from your list that's easy to procure. I've used house brand UTHFs from Rural Kind and TSC for decades and never had a problem. Given my experiences with ST fluids, they do very well also.

My point is that you're overthinking this; from the list you made, any of them will be more than sufficient. Get the easy/inexpensive option and save the worrying for something else in life.

Call me silly but an oil from the majors Shell, Mobil, Chevron etc is always a good bet . John Deere doesn't make their oil.
