I have been told previously to not change my TC33D over to synthetic for the engine oil to at least 50 hours have been run. Does the same hold true for the hydraulics?
I think I'm going with Amsoil. But I do have some questions.
1) Can I run the same hydraulic AMSOIL product where ever NH 134 hyrdaulic oil is used? IE power steering, front axle,etc. Can someone tell me the correct AMSOIL product so I make sure I am buying the correct one?
2) Should I run the standard or heavy duty deisel engine oil product?
3) Do I need to change my hydraulic and hydrostatic filters when I change to the new oil?
Lastly, anyone hear any news on the new FEL for 33d's?
Thanks
Bob

These are my opinions. I believe Amsoil makes a fine product, and I have used it with great results in my cars, however if it is not specifically labeled as meeting manufacturer specifications they would have legal grounds to deny any warranty claims that they think are fluid related. Amsoil can *claim* their products meet or exceed manufacturer requirements, but their claims are worthless if they have not actually submitted their products to the standards organizations for testing. The labeled rating should show what testing has been done, any word of mouth claim by ANY Amsoil representative is worthless if not backed in writing. As far as your filter question, I cannot see any reason for changing oil without also changing the filter.

I think of oils as pretty universal stuff. There are the standards and manufacturer should say which ones are acceptable for their product. Within that there likely are a bunch of products that all work about the same. Of course, both the manufacturers and oil companies are going to try to convince customers that their product is special.
I can't see any big reason to rush into use of a special oil. Few of us are ever going to wear out our engines using any recommended oil provided the maintenance intervals are met and appropriate grades are used. I do what ever is easiest and for the fewest stops when I have to go to town. Most times that ends up as the dealer and manufacturer's oil because I like my dealer and I'd just as soon do all my tractor buz in one place.
If 'heavy-duty' refers to 15W-40 grade engine oil, that is a good summer oil for doing heavy work on very hot days. It also can be a liability during the winter in places where it gets sub-0F. An owner's manual should have a table that gives grades to use for different temperature ranges. We have cold winters and I use one that works OK year around but I do avoid doing heavy work on the few very hot days we get. That may be more for me than for the tractor but it's a good excuse. Hydraulic oil also comes in multi-weight grades. The NH multi-grade version of 134D is F200 and your dealer might recommend that if you're in a cold area.

Tractor hydraulic oil has to do a lot of things. Besides the obvious it must also be compatible with the wet brakes found on most models of tractors.
The only real advantage I can see for synthetic hydraulic oil is it's ability to handle extreme temperature conditions such as operations at -30F. But you will pay through the nose for that ability.
Last I heard Amsoil synthetic hydraulic fluid was over a hundred bucks for a five gallon pail. That is a lot of money to pay unless you are in Fairbanks.
As far as I can tell the only tractors out there that require something more than normal tractor hydraulic fluid would be the Kubota BX series. They need Super UDT which I think is a synthetic blend.
For example, I had been using high temp, high pressure synthetic wheel bearing grease to lube the fittings on my loader and backhoe.
If you think about it it makes no sense to spend 6 bucks a tube when the $1.79 stuff will work just as well, since there is certainly no high pressure or high speed stuff going on in my loader bushings.
During the warranty period especially, I would be real reluctant to use anything that didn't have a direct cross reference to the fluid specified in the owners manual. It should say on the container that it meets NH specs or you are taking any warranty issues into your own hands.

I am a proponent of synthetic oils. But, there is no reason to rush to make a change on a particular tractor.
I have used Amsoil before with good results on gasoline engines, but I generally buy my lubricants from one of the large oil company brand names now. I never had a problem with Amsoil, but the availability of the brand names is better and they are often on sale.
When changing over to a synthetic, it is useful to change the filters and to get rid of as much of the conventional lubricant as possible. The conventional lubricant is essentially a "contaminant" in the synthetic oil and will not stand up to the same hard use as the synthetic will stand.
I plan to use Shell Rotella T synthetic in my TC45 engine and I plan to continue to use NH 134 in the rest of the tractor. There is some recommendation to use another lube in the front axle of the FWD, but I have not decided whether to change that or not. ....

I converted to synthetic hydraulic fluid last fall for my Kubota B2150HST along with Shell Synthetic 5w-40 for the engine. I bought 100% synthetic Chevron THF at a Chevron oil distributor in Port Huron Michigan and paid 78 buckeroos for a 5 gallon pail. Says on side of pail "MEETS John Deere Winter and Summer requirements" along with New Holland, Kubota, Massey Furgason, etc. Paying those Amsoil prices is sometimes insane. I noticed better quickness of loader hydraulics in a cold Michigan Winter considerably. 78 bucks for 5 gallons is not all that bad of a price compared to what synthetic offers in terms of wear and performance. I think Amsoil is a good product but for the price, offers nothing more than Chevron THF offers. ....

The price has gone up a bit. I think I paid about $60 for 5 gallons last year.
Just to be clear, I use Shell Rotella Synthetic in the crankcases of both tractors and Chevron Synthetic in the hydraulic system of the BX.
Both products meet industry standards for warranty requirements and are labeled as such (as Jeff pointed out). ....

Yes, my loader slows down when it's very cold even when using multi-grade hydraulic oil and sometimes I use magnetic heaters on the sump as well.
Warm oil from the TX cools down in the cylinders and after about 20-minutes, putting the boom in float sort of eases the bucket down in slow motion when the temp is around -20F. It speeds back up for awhile when oil from the TX is in the cylinders. The float position may not work at all if I were using straight-weight hydraulic oil. I use NH F200 or an AGCO equivalent. A true synthetic would work even better in the cold. ....
