neilw -- Question, what Amsoil oil is $26 for the diesel tractor. the 15w-40 is $20 retail?? I can buy it and it shipped to my house is around that price for 15w-40 what should be used in our diesel tractors.
Since our tractor do not get that hot I would NEVEr use Delvac 1 in ANY turbo application . The stuff sucks at high tempos and will kill a turbo.
Eve nthough I like Amsoil LE has the best gear fluid out there hands down. Not Amsoil, nor Redline etc.

shady1701 --- Do an oil test and watch the rsults! My tests were LOADED with all kinds of junk (ie, solds like carbon, Fe, etc). Do what you wish but I know what the results came back like in my app....... Yuo would not catch me using that stuff if you even gave it to me for free!
My analysis of the amsoil TSO 0w-30 on 8/6/1999 with 6700 miles poised an exteremly increased level of OXD and NOX with a tbn was 4.6 and suspended solids were .3% this is with the bypass filter and amsoil std filter with a 1996 5.7L with more or less 40K miles. I did same test with mobil 1 and showed about 13% less oxidation and nitration and about 2 more on tbn at ~6500 miles..
This was done by oil analysers inc a subsidary of amsoil in superior wisconsin..

I also tried there 5w-30 "super" diesel oil vs the delvac 1 and 15w40 marine/hd diesel at one time on my powerstroke at increased drain intervals using std filters nothing impressed me and the "solids" is probaly all the junk the delvac desolved out of the engine block were the amzoil was congealing and coating everything with soot and carbon where it couldn't suspend it in the oil that's why amzoil looks so crystal clear.(out of sight out of mind?). then you put some good quality oil it'll loosen up the krud and turn black.. /forums/images/graemlins/grin.gif

"shady1701 --- Do an oil test and watch the rsults!"
My reply in "King of Oils"---- a single oil analysis or even several after switching around oil brands does nothing to proove anything. Your control of the experiment is lost. It is the trend--the TREND--that oil analysis is useful for not direct back to back comparsison of different oils in the SAME engine. That is a misuse of the oil analysis concept that will draw erroneous conclusions /forums/images/graemlins/confused.gif. I agree with the other fellow, Mobil 1 is known to have very strong detergent/suspension/dispersent properties/capacity for everything commonly found in an engine other than LEAD, which should not be found in modern fuels.
I am not trying to embarrase you GXER or belittle your thoughts but I think your concept is flawed. Mobil/Delvac 1 may not be the best oil and the value of synthetics may be widely dissagreed upon but Mobil 1 is a quality oil and it has been prooven over and over again in various studies some of which have been referenced in these recent threads. Even in the case it is not the very best the difference between it and the other presumeably better synthetics is minor especially when it's fairly low price and wide availability are considered as well.
It really is weird this oil stuff, GXER won't use Mobil ever and I would not use anything but, amazing the differences in opinion /forums/images/graemlins/shocked.gif /forums/images/graemlins/grin.gif.
I have used Mobil 1 in VW bug engines, various motorcycle engines, small power equipment including Briggs and Stratton, air compressors (in the compressor), dune buggies, several boats way back and a variety of cars and trucks including Fords, Toyotas, Subarus, Jeep, Renault, and VW Vanagon and now a Kubota tractor(s) . Some of them were tracked with oil analysis for trend, none ever showed unusual signs of wear or indicated anything amiss with the oil. I have also used, Shell X100, Exxon Uniflo, Castroil and --oh--I cannot remember anymore and I was not displeased with any of them--except for the Arco graphite and the Qauker Stale and I don't think much of Pennzoils lowend products either. Valvoline looks good too, especially the new wear max stuff or whatever they call it. Lot's of good products, diffucult to find something really bad (other than Quaker State).
Mobil 1, factory fill in Aston Martin, Dodge Viper, Chevy Corvette, Mercedz AMG, Ford Cobra R, Porsche, meets M111 Europeon standards for triple pass testing, meets/exceeds all API and all known manufacturers requirments (whether they admit it or not). J

Yeah, it was pretty bad. I used to read Popular Science magazine when I was just a youngun. It was there that they had a big article--not a paid advertizment--and they extolled the virtues of Arco Graphite. They had all sorts of graphs and test tubes and bunson burners and it all looked impressive to a Grad Student with a new Subaru. I ran down to the autoparts and spent my stipend on Arco oil. What a calamity belched forth from the Subie when I crankerd her after installing the oil. I changed it in the parking lot of the store just like a good redneck --err, grad student should, yeah, I used a pan /forums/images/graemlins/grin.gif. I was so mad I thopught I might cry /forums/images/graemlins/mad.gif. Popular Science failed me and as a result brought into question my entire life source of information, Woe upon me /forums/images/graemlins/frown.gif. The old parts guy, took me, now totally in deppresion by the arm and showed me Mobil 1, a light came down upon me from the sky and the crows were happy. Put this in there sonny boy. I did, he was a wise man /forums/images/graemlins/cool.gif. I am sure he is long passed away, thanks ol' feller, you steered me right /forums/images/graemlins/smile.gif. Oh, and I don't read Popular Science anymore /forums/images/graemlins/mad.gif. J

Check out this oil study. Not diesel related but interesting.

How could you use any thing but Mobil 1 with that kind of experience. We are in total agreement on Quaker State oil. It screwed up my 48 Cadillac flathead V8. It started using so much oil I had to carry a 2.5 gallon can of RayLube in my trunk. I think I used Raylube in all the old junkers I had after that experience. Are there any unbiased independent reports on all these different oils? Gary
