Bought super UDT from my Dealer

[Bayrat]

<font color=red>I suppose I am one of those foolish people they make the Super UDT for, I bought some today for my 2910</font color=red>. My dealer carries both N/H and Kubota oils as he sells both tractors. He had only one gallon containers so it was even more costly than the $60 a pail I have read about here (13.95x5). They actually did suggest the standard fluid in either N/H or Kubota and said they mix and match as needed. My machine is still under warranty and I really wanted to use synthetic but I will wait until the 300 hour change to avoid possible future conflicts should a warranty repair be needed. I guess I am a big orange sucker at this point /w3tcompact/icons/laugh.gif.

So maybe you paid a little more, but you have the peace of mind KNOWING that you have what Kubota recommended and your warranty is good. A little peace of mind is sometimes worth a few bucks (to me at least)./w3tcompact/icons/wink.gif

Kind of my line of thinking too Bird, but there is a good deal of evidence here that points to less costly products that are as good or better /w3tcompact/icons/hmm.gif. I used Agway UF in my B7100 without a hitch but that was an older design machine and the jug met all specs for that application at the time. I am still struggling with synthetic engine oil, I just put semi in my truck and one of my mowers and am probably going to run it in everything as I change out. It is about twice the cost of the Quaker State I use in the Jeep but since I change oil more often than required, the $4+ a quart for the other is hard to swallow.

Yeah, I understand. The manual with my '95 B7100 specified UDT (I don't think they had Super UDT back then), but it also listed a half dozen other brands by name. Then the manual with my '99 B2710 specified UDT or Super UDT (no mention of any other brands or specifications), and I found that the two dealers in my area didn't even stock Super UDT (one said he'd never heard of it - guess he hadn't read the owner's manuals/w3tcompact/icons/laugh.gif). And the only time I've ever used synthetic oils was when I put Amsoil hydraulic oil in the B2710 to see if I could tell any difference. I think it might have run a little cooler and been a little quieter, but I can't say for sure - you know how you sometimes see or hear what you're wanting or expecting to see or hear./w3tcompact/icons/wink.gif At any rate, I think it was too expensive and I don't like their marketing methods. So I'm still running my Quaker State in the car and pickup (used Chevron Delo 400 in the tractor engine).

no such thing! if u feel better with super udt, then that is what u should have done. i sometimes spend more than i should because it makes me feel better, what anyone else thinks don't matter.

I think you ARE running synthetic already!! It was my understanding the super UDT was synthetic and was why it was reccommended for colder climates. (Lower pour points and better low temp viscosity characteristics). I guess my position on fluids for the tractor is the changes are so infrequent I don't mind paying a little more for the possibility it will help the equipment run longer with less wear/tear. Having bought new I expect the tractor to last a LONG time if maintained right.

 

[Bayrat]

I was wodering that myself but it states on the jug that it is compatible with all other fluids. /w3tcompact/icons/hmm.gif Would a synthetic say that? The semi-synthetic engine oil I am using in the truck and tractor have that on the label but then they are not a full synthetic either.

Semi-synthetics are not your best deal if you are buying them premixed. They are usually priced as if they were about a 1:1 ratio of synthetic to conventional but most apparently only contain about a 1:9 ratio so that they aren't deceptive in their claims of "synthetic blend". You much better off to do as my father does; buy one quart of synthetic for every three quarts of conventional that you buy and mix it yourself. Myself, I run full synthetic in my vehicles and will probably switch in the new Kubota by my third oil change. The old Yanmar just leaks to much oil for me to use synthetic in it. It may be overkill (and probably is) but it does give me a little better feeling about my machinery.

JeffRey.

What your father does brings up an interesting point. I have traditionally stayed with high quality conventional oils (stuck in the 3000 mile change mode) (6 cars, five drivers, in the country & lots of miles). I have tried several blends and I agree, the % of Synthetic is probably fairly low 10% - 20% at best and if you do the cost comparisons, you can save a bunch of money blending your own.

Question, since the synthetic is fully compatible with conventional oil, I suppose you can come up with any % blend you desire based on the economics you wish to achieve and perceived performance improvement characteristics? Based on a 4 quart change, 3/1- 25%, 2/2 - 50%, 1/3 - 75%,you could achieve several Conventional/Synthetic blend mix ratio's. I suppose as long as you stay with the same weight say 5W30, the additive package mixes OK... Does you father stay with the same brand in the mixing or does that even matter? I suppose at some point you might as well just go full synthetic....

Surge,
I think he is using the same brand of synthetic as the conventional oil but since the synthetic is fully compatible, I wouldn't think that it would matter at all.
I haven't quite bought into the extended oil drain interval with full synthetic, but I do push my changes out beyond the 3000 mile change mode to the engine manufacturer's max. recommended interval. For my Tacoma, that is a 6 qt. change every 7500 miles. By adding in the time I save not changing oil that extra 1 1/2 times, the cost of the extra conventional oil I would have bought and the hassle of disposing of that extra oil, I figure I come out a little ahead with full synthetic. If I get any extra benefits such as more MPG or longer engine life, those are just icing on the cake. I haven't seen anything yet that would firmly establish that those benefits really exist though. Maybe they do! /w3tcompact/icons/wink.gif
