What make/model are we talking? I would be leary as heck running that where some tractors would require a good hy-trans with wet brakes/clutches.

I also would not run it anywhere designated for 80w-90. Then again, I don't mind having more than one oil around.

most tractors today run utf in the tranny and rearends... so in that aspect he's correct. but running it in the engine... dont feel good about that at all. utf is a cut below motor oil when it comes to additives as it as to allow for wet brakes and for wet clutches by design. It has be used in these applications since 1965 or longer, so again, no surprise there. but hd motor oil has a lot more additives and cost much more that utf.. So I would keep the utf in the back and the hd motor oil in the front.

Find another mechanic before he wrecks your equipment with advice he heard from Bubba down at the diner.
Hydraulic oil, trans hydraulic oil and trans hydraulic oil for use with wet clutches. GL1, GL4 & GL5. High detergent motor oil and low ash motor oil. They are all different speced oils for different applications.

Sounds like those motor cycle oils rated for use with a common crankcase, clutch and gear box.
To cover such a broad spectrum of applications. There must be some compromises in the additive package and applications.

I'd suggest sticking with the owners manual. Of course it depends a bit on the tractor and therefore the age of the tractor (newer technologies in oil).

Most likely the friction modifiers aren't added. I also expect this is being used in Europe. They are advanced in some areas we're still behind in. Like the 3,000 mile oil change. And the 100 hour oil change. People change slowly but they do change the habits that were passed down to them. If nothing else cost will force the change.

Example: the ULSD fuel I use gives me the longer use of diesel engine oil. Going 300 hours with no problems and oil isn't looking dirty either. Have a newer Deutz engine and owners manual says 500 hours or once a year on oil changes.

I agree with what buickanddeere said. In some cases oil can RUIN the inside of your transmission, John deere had a problem with people putting the wrong oil into power shift transmission's, IT would literally EAT the clutch disk material away. I personally am a huge fan of hy-tran hy-guard etc that john deere sells. Ive never once had any problems with john deere oil. For engine oil, I always use Rotella, in both gas and diesel tractors.

It may be the way to go in the near future. Remember when Mobil 1 came out-nobody was going to use synthetic oil. Guess wha? This new stuff will have to prove itself fist I think. I haven't switched to synthetic yet. My Buick Lucerne book says to change when computer says to (Under normal conditions). I change about every 3000 miles.

Might be OK for some applications. It does not appear to meet any of the hytran specs for tractors that use a common oil for trans and hydraulics.
No mention of it replacing the oils like JD J20-J21 or Case IH MS 1207-09-10. etc.

Engine, transmission and hydraulics? Get a better mechanic quick, he is creating his own business. Engine, gears and hydraulics all have different lubricating needs. There is NO oil made by anyone that meets the requirements of all.

STOU has been and gone, it came on the market in the UK in the mid to late 1960s, and was fine for most tractors built up untill the early 1990s. I have used this oil for years and never had a problem when used where reccomended. Now we are going back to dedicated, separate, engine and transmission oils now that powershift and IVT transmissions are the norm. Great in all the MF tractors exept for the power steer, Ford thousand sereis, and David Browns, and John Deeres up to the 6000 range but you could not use it in I-H tractors that needed Hy-tran. Now we use JD Hy-Guard in the Deeres, which goes in the older tractors that origionally used STOU oils. Check the specs and use where reccomended, this is not new by a long shot and has been well proven over many, many, years.
