Rotella 15-40 oil posted on Agriculture.com

cowboydoc · Jan 21, 2005

Amsoil brags about being new classification certified. Rotella passed that test with it's old oil without any modifications. Rotella passed all tests for the highest standards of diesel engines with premium performance specifications relating to API CF-4, Caterpillar ECF-1, Cummins 20078 premium choice, Mack EO-N Premium Plus 03, Mercedes Benz 228. and Volvo VD-3. Mack has the highest standards of any engine mfg. out there and Rotella passed their requirements. Classifications that even your beloved synthetic Amsoil does not hold. Rotella is also certified as a warranty required oil (this means that the oil is ok'd for use for warranty purposes for those people that want to read more into this than I meant) for ALL diesel manufacturers in the world. Amsoil doesn't even come close to that.

They also did a year long study of 185,000 in the extremes of Austrailia. The results were little or no wear, minimal sludge buildup, excellent lubrication performance, and virtually no deposits, oxidation and carbon buildup, excellent soot dispersing, and no acidity.

Rotella also routinely tears down thousands of trucks every year in every fleet to determine wear patterns. A poor overhaul rate is in the 500k range. Excellent overhaul rates are in the 1,000,000 mile range. Rotella engines are always in the excellent rebuild categories.

Unlike you I'm not saying Amsoil is a bad oil. I'm sure it is a very good choice for people if that's your cup of tea. But Rotella is no worse of a choice. When used according to mfg. recommendations, aside from some better cold starting issues and a possible 1-3% increase in fuel mileage you're no better off using one or the other.

Rotella is also certified as a warranty required oil for ALL diesel manufacturers in the world? Says who? I have never EVER read in an DIESEL MANUAL that I must use Rotella!

You can use ANY oil in ANY engine as long as it passed the proper spec's; which Amsoil does. LOL. What planet are you on??????Amsoil has passes these spec’s since I have been using there oil. Nothing new here. It is even on the “internet”.

( They also did a year long study of 185,000 in the extremes of Austrailia. The results were little or no wear, minimal sludge buildup, excellent lubrication performance, and virtually no deposits, oxidation and carbon buildup, excellent soot dispersing, and no acidity. )

Lets see the study then? I do not know what you stated by the above What is low wear (5 ppm Iron, 20% Al)? What is minimal sludge (10% 20% etc). If no acidity, what was the TBn and TAN #’s?

( Rotella also routinely tears down thousands of trucks every year in every fleet to determine wear patterns. A poor overhaul rate is in the 500k range. Excellent overhaul rates are in the 1,000,000 mile range. Rotella engines are always in the excellent rebuild categories. )

500K on trucks is not a lot when they are driving across country! That is about 1.5 years for some!

I never stated Rotella was bad. I said it is time to step up to a real oil. There is more to it then starting temps and possible MPG increase. There is WAY more to it!

double post..sorry

Here we go. Do you synthetic guys never stop? I'm glad you're happy with Amsoil. We're happy with Rotella and our oil analysis shows it's doing a superior job.

All I am posted YET again, is post something to back it up! Any used oil tests! Any data showing I have to use "Rotella oil" hmmmmmm

Anything other then Shell propaganda???

Do you synthetic guys never stop? 
That's right Richard. I like synthetic oils, but I don't drink it or worship it.

Nether do I.

It just amazes me that they are 5 groups of oils; and people think #3 is great. I guess most like 2nd best or 3rd best in this case. Why settle for #3 when the "higher" levels are only a few pennies more. /forums/images/graemlins/confused.gif

One reason is that they are a real pain to buy. They have it set up to where you have to blah blah blah to even get it. If it is so good why don't they make it more easily available. Are they afraid of the public in general or are they afraid that if everyone starts using it that they will find a problem with it? More sales = more money.

I can find it in my small city in about a dozen shops.

JerryG · Jan 21, 2005

I have never seen it in any kind of shop or store. Where I live or when I use to travel on business. And I did stop at car shops, because that has always been one of my interests from my drag strip and oval track days. I will give you, that you live in different place than I do and that I wouldn't live there for anything. If I had to live there to get a certain oil, I would ride a horse.
