Back end

Wal-Mart prand oil is manufactured by Quaker State. I called Quaker State and asked them about there GL1 product line. The GL1 gear oil is a mineral oil and will meet the specifications required for the trasmission.

The Technical answer line person I talked with did inform me that the Wal-mart store label brand is made to the minumum GL1 spec limit while the Q-State brand was made to a higher than spec. limit.

i.e. the QS oil will have better adheasion, thermal integrity and internal structure. But both will meet the GL1 specification for use.

Thus, "MY" conclusions
1) I would use the Wal-mart brand at $22/5 gal vs. TSC at $16/2 gal. may have to change out more often.
2) I would buy the Name brand if I could find it.
3) I would ask MF who actually manufactures their M1103. Oil. and call that manufacturer.

My personal conclusion is that I am avoiding using the R&O oils. I have been using GL1 oil from TSC labled for fords. This is expensive compaired to Walmart's GL1 oil made by quaker state. Thus until I can prove that TSC's GL1 is made to a high standard than Wal-mart's I will use Wal-Mart's. If I can find QS's GL1 or another manufacturer's brand GL1 I will purchase that. But if the choice is between two store brands anyway....

Sorry to be wishy-washy on a firm answer, it is just that I do not have the back groung to speek athoritatively. I just made a few phone calls and answered basic question left on the table.

The long answer.....
Back a month ago we had a long discussion on oil. (feb 27th, 03) During that discussion I made the following "conclusions"

1) Manual calls for straight 90wt mineral oil.

2) GL1 rated oil labled for Ford N's at TSC is acceptable.

3) MF recommendeds M-1103 pure mineral oil

Question: Is GL1 pure mineral oil? Is it equivelent to MF-1103?

Another Jeff said he found the R&O stuff and GL1 at wally world at a good price ($23 5/gal vs. $45 at TSC) So I said to my self..."Self, call wal-mart find out who manufactures their store brand."

I found out it was Quaker State and then called their tech. support line. The tech support line and the QS web page confirmed that..

1) they manufacture Wal-mart store brand oils.
2) Wal-mart GL1 does meet the GL1 spec. Did not say if it exceeded it or not.
3) GL1 was pure mineral oil even if the lable did not specificly say it.

As for R&O (modern trans-hydro) oil. Their are some who say it is not friendly to the bronze bearings in the older tractors. (Ray-IN if I appologize if I am miss-quoating) I just have no expierence in here but Ray-IN is one of the handful of regular posters whos opinion I trust.

Big Dean also has a great background... His post

"We had service bulletins in the early 1980 from Massey Ferguson tell us that it was better to use 10 W 30 in the engines even old engines. The viscosity changed according to the temperatures but I don't remember the details on that. When the Per-A-Tran III came out we were told to use it in place of the M1129A, M1127, M1110 & M1103 80/90 wt. mineral oil. Per-A-Tran III works fine if the hydraulics are in good shape. With a little wear on the hydraulics when the new oil gets hot the lift stops working on tractors that used the M1103. They had so many complaints about this they came back with the M1103 in about 2 years or less. We also had a service bulletin When the oil company went to Dextron Transmission fluid not to use it in place of the M1110 or type A transmission fluid that the seals in the Massey Ferguson tractors were not compatible with Dextron oils & to use the M1129A or today it is Per-A-Tran III in place of it. This is what I have always went by I figured the Massey engineers new more than I did about what was best for their tractors. There has been many service bulletins on many thing that are different from what is in the manuals. One being some head torque specs & gasket changes on some engines."

i.e. was the GL1 oil from Wal-Mart acceptable. Was it mineral oil or not because the label did not say etc.

This was FYI to anyone interested.
