Got an oil, change coming up in a while just bought this tractor a month ago, I'm curious what oil you use in your tractors or what is the best oil to use?

Not so sound rude but it would help if you told us the model of the tractor. So far we only know that it's a Massey Fergunson.

My bad sorry it is a 2017 GC 1705 with just the loader!

Rotella T5 15W-40 Synthetic Blend Motor Oil supposedly "Heavy Duty Diesel" . I do not particularly care of it is synthetic or not so long as the letters show it is certified by the tractor mfr as OK for my tractors. Shell Rotella that says diesel on the jug is compatible with essentially all of them. Tractor Supply and many stores carry it.

I think people overthink it. Any quality name brand oil that is diesel rated is good. A synthetic is better. I figure if you use a synthetic don’t change it early because you’re just changing oil that is still good. Look in your manual, a lot of makers are specifying lighter weight oils like a 10w-30.

+1 On don't over think it.

As long as you use a good diesel specific oil, you will have zero problems.

Rotella T6 full synthetic 5W-40, is under $25 a gallon at Walmart. A good brand with a long proven track record, at a very good price.

👆 As above, Rotella T6 full synthetic 5W-40 is probably the most popular for engine oil. Myself, I use Mobil Delvac 0W-40, almost 20 years now in the GC, due to availability and price.

Agree with all of the above. Congrats on the new tractor!

I dont know that I’ve said anything against an oil but I wouldn‘t run the Triax oil. It may be fine but I’ve never heard of it.

It’s been several years ago but I read an article about oils that didn’t meet specs. It listed the oil by name and why it didn’t meet spec. Some were just garbage. All of them were off brand names I’d never heard of and the list was long. I wish I had a link to that list but it’s old and out of date anyway.

Used this on my last oil change. seems fine.
I don't believe my calculator is fibbing but... That is $26.60 per gallon (in a 5 gallon pail) not adding in sales tax, which you will pay on Amazon. So, lets call it $27.00 a gallon, which is higher than Shell Rotella usually sells for at your local box store.

My comment to the OP is, follow your owners manual as to what you need to change with.

Finally, I really dislike oil threads so the above is my only comment.

Keep in mind that there are a boatload of repackagers out there and very few actual refiners. Lucas as well as Amsoil refine NOTHING, they just but in bulk and repackage and label (and maybe add some proprietary ingredients) and the jack up the price.

At the time I ordered it, only T4 & Traveler's was available around me. Not saying it's cheapest or best, but am saying it works fine & is readily available. Had the same experience with their UDT2 substitute for the Kubota. Now I just need to find a good TO4 for the Cat.

Are you using your tractor during the winter? not sure how cold it gets in Tuscola but I would assume cold enough... will you change your oil once a year or twice ?

Yes, I will use the 1705 in the winter if we get heavy snows. But it is always in a heated garage when not in use. Temps get below 0 and sometimes windchill is -20 below.

in this case (heated garage) I would get 15w-40 or 5w-40 despite your owners manual probably calling for 0w-30 to 0w-30 ... I put 0w-40 in my massey (I don't have a heated garage) and it is calling for 0w-30 to 15w-30... as for the brand my opinion is oil is oil as long as it's certified and from a known company.

Your owner's manual will tell you the specification (e.g. CK-4) and recommended weights (e.g., 10W-30). Any oil that satisfies those two criteria will be fine. Don't need to overthink it, the engine manufacturer has already done that for you. I use Rotella in my diesel engines as it's readily available.

An issue with the owners manual is that it is basically the same manual that was copy and pasted together in 2002. 0W engine oils were considered arctic service, 5W oils were pretty well nonexistent. Oils have come a long way in 20 years. Agco/MF did not spend a lot of money on technical writers to update the GC series manuals.
