Mobil 1 in a Yanmar (John Deere) diesel???

Re: I have used Mobil 1 in 3 diesels

In fact, I use it in all my vehicles. A friend who is a Corvette nut got me on to it years ago. He used it in cars and in his JD lawn tractor.

I have used it in two Kubotas and now my JD 970. I run 15-50 all year. It pours like water and I think offers great high temp protection. It is a way to extend oil changes on cars and trucks, and that it is important if you are racking up miles and 3,000 miles comes before you know it. I now try to change in vehicles every four months, and yearly in my tractor whether it needs it or not.

Mobil One filters are superb too. Got one on my tractor.

This is one slick oil. If I were running my tractor full time, I might look for something heavier, like straight 50 weight, esp. if I could find it in synthetic, but maybe not. I'd watch the temp gauge. My JD seems never to get hot as it is.

Incidentally, an excavator got me on to a wonderful grease: John Deere's HD Special Puyrpose Moly. It is the only thing he has found that will stick to his dozer all day. Now it's on my tractor and bush hog.

P.S.: Read owner\'s manual on break-in first

I happened to be doing so for my JD the other night and noticed that they said to wait 100 hours (as I recall) to use the Torque Guard JD oil brand they like, because it is too slick for breakin.

Thus I think you should wait AT LEAST that long before using a synthetic.

If you want a good synthetic oil that cost around $5.00/quart. Check out John Deers 0w-40. I've seen the virgin oil analysis and it looks like really good oil with a big dose of calcium, good dose of moly and some antimony to handle internal rusting of the engine.

OK, I decided to buy Pennzoil Longlife 15W40 which has a CI-4 diesel rating and it appears to have moly.

My other choices were Delo, Delvac, Rotella, and Rotella synthetic. Would any of these been significantly better? (The Rotella synthetic appears to be hydrocracked Group 111 which is really fake synthetic except for price)

OK so what is that?

I'll give you this little bit.. auto engines operate at full load 30% of the time..OTR trucks 50-70%.. Tractors/lawn equip. 90%.. that's how they configure most oil formula's

now going on that the idi diesel's call for CF loading.. there's realy no need for the CI-4 needed for soot loading.. egr loading and the higher injection and all the new garb oops carb/epa stuff..

Looking at visc... most of these call for 30w... newer engines now operate on 10w-30 and 5w-40 such as newer jap, euro and other diesel's.. with gas leaning on 5w-20's..

I think mobil 1 is fine for these little diesel's the pao is ok but looking from an operating point you need to get something to stick with i don't realy think you need anything other than 15w-40 rotella,delo400 etc.. at the 100hr intervals but any type of synthetic and oil even SL is far superior than 20 year old technology.. The notion that a CF product isn't good enough than look back 20 years?

Also consider seals they tend to want to look more from the smaller molecular structure as per the tech expert on rotella's forum i posted that question..

Just food for thought..

Hello all,

New here. Nice forum. Lots of good info.

I have a 955 that currently has 340 +/- hours; purchased it with 140 hours on it about 2 years ago. I've done two oil/filter changes (one at 200 and one at 300 hours), using Castrol Syntec 5w-50. It has a CF/CD rating. Reading all this stuff about CI4 and CH4, etc.., has made me wonder if I should run out there and change it right away or not /forums/images/graemlins/confused.gif

I noticed two things with the Castrol in there - the cold startup and throttle response are definitely better than with whatever oil had been in there. I just want to use whatever's best for my baby. /forums/images/graemlins/grin.gif

Pacesetter,

Group III hydrocracked synthetics are petroleum oil that has an extra refining step to break up long chain molecules. The FTC has ruled that they can be called "synthetic" when in fact, they are still 100% petroleum oil.

As far as Amsoil being expensive, on the Preferred Customer plan the 15W-40 HD Diesel oil is $3.80/qt when purchased in case quantities. Add shipping costs and you are still about the same as Mobil1.

Re: P.S.: Moly?

When did deere and pennzoil put molydisufide in there oil? and what is the cost on the 0w-40 JD oil?

chevron has 0w-40 and also mobil 1 in there euro cars? maybe jd has one of them?
