rotella T better than valvolene?

[DieselPower]

Some people use EVOO as a diesel fuel lubricity additive. Not sure how effective it is but it is done.

Lifted from another thread, in the Ferrari forum.....don't know if it's true or not, reads interesting.....

"A bit of information directly from a shell engineer. Note that at the end he states that the base stock in Rotella T 5w-40 synthetic (available at walmart for $14 a gallon) ,Shell Helix(Ferrari dealer $16 a quart), and Ferrari's formula 1 oil cocktail is the exact same thing minus different additives. Is the highly rated Rotella T synthetic 5w-40 another credible alternative to overpriced Helix? After all, the Rottela t does meet and far exceed all current testing standards (SL, Sj, etc) not to mention an incredible viscocity index of 178 degrees c (mobil 1 0-40 is 168 c).

"It is true that ROTELLA T Synthetic is Group III (not PAO) based, but you must keep in mind that not all Group III base oils are created equal. ROTELLA T Synthetic is made with Shell's XHVI base oil, which unlike other Group IIIs does not begin as distilled crude oil, hence of all Group III base oils, XHVI is truly the only one that can legitimately be called "synthetic." XHVI is a wax isomerate, meaning that it is made from the slack wax removed from distilled crude in normal solvent dewaxing. This slack wax is catalytically transformed (isomerized) and hydrofinished into a chemically pure base oil which rivals PAO in virtually every category. There are other "synthetic" oils out there based on Group III, but Shell's is unique in that it uses XHVI base oil. Chevron and Petro-Canada produce Group III base oils that come close to XHVI, but even though these oils are all hydroprocessed and utilize the same type of isomerization technology employed in the making of XHVI, they are not the same thing. Only XHVI is made from pure petroleum slack wax and its CAS number is 92026-09-4. The CAS number for the more typical all-hydroprocessed Group III base oils is 64742-54-7. If you want to know what your "synthetic" oil is made from, take a look at the MSDS and look for these numbers. (The CAS number for PAO is 68037-01-4).

In brief, don't be so quick to dismiss Rotella T Synthetic as just another "synthetic pretender." It's made with the same base oil as Shell's Helix Ultra, and everytime you see Ferrari win a Formula 1 race, that's the oil in the engine.""

WOW, thanks IH3444, although i am totally confused on all of these API ratings numbers and such. Can someone give me a low down on what i'm looking for when i look at a can (ooops that ages me....i mean plastic)quart of oil??? I'd like to be at least as smart as I act??? hahaha Also, what can you tell me about the difference between Rotella T and Rotella synthetic as far as length of oil changes, what effects on the engines etc....I have a couple later (01,02)model IH with the DT engines and they've both had to be rebuilt at approx 125,000 miles. Don't understand it, we serviced them regularly and used Rotella T in them since new. I don't think it's the oil but i'm sure curious if i should use synthetic in them or in my NH tractor???

Diesel,

Here is the reply I received from Conoco:

Conoco Power D Engine Oil will not be updated to CJ-4, it will remain a CI-4 Plus product. We do, however, offer two different CJ-4 products. Our basic offering is our Fleet Supreme EC in 15W-40 and our premium offering is Guardol ECT 15W-40 which would be the Power D equivalent in a CJ-4 product.

So much information to digest in one day, I should go and take a nap.

Thanks, Les

Everything I know about oil will fit is a coffee can.. so here is the most crude ( pun intended ) basics as i understand it.

2 clases to look for "S" reated oils, and "C" rated oils.. S is for gas engines, and C is for diesel.

( I -think- S stands for spark ignition... I would also guess C for compression engines.. but am thinking someone told me that was wrong.. etc.. )

Ok.. now the standards..they are alphabetical.. therefore oil #1 may be a CD oil and a newer one may be a CH oil.. etc.

For instance. the oil I looke dat, the fleet oil was rated CI-4.. the Rotella was rated CJ-4 ( j comes after I, and is a newer standard ).. Now what each of the standards means? I dunno... Obviously dieselpower DOES know, cuz he was informin' me about the 'j' meaning something about the addative pack and special filters on 2007 engines.. etc..

Everything you ever wanted to know about what API licensed oils are. Straight from the horse's mouth, the API oil guide.

http://www.api.org/certifications/engineoil/categories/upload/EngineOilGuide2006.pdf

Sorry Soundguy, you got the S and C wrong. No cookie for you.

S = Service C = Commercial

The number you see after the C on commercial oils is the type of engine either 2 or 4 stroke. Very few of the old 2 stroke Detroit's left anymore so there are not many CD-2 or CF-2 oils left anymore.

Thanks Sound!!! That helped a bunch!! DieselPower you too.....that link educated me alot.....i've been around mechanics, engines and equipment all my life and never really knew what all of that meant.....i'm going to try to research a little farther now with you guy's help and then go to the store and try out my new knowledge on some of these name brands that i've been just staring out all these years and basing my opinions on just "brand names" that "people" have recommended instead of forming some opinion of my own based on specs. Even if it doesn't matter once you get to the spec of your particular engine, it's a real good feeling to know what you're doing when you lay your money on the counter and not just buying brands that have the coolest advertising on TV.

Quote from the API oil guide

"Use only the recommended API category: “S” for gasoline engines;“C” for diesel engines"

"Oils designed for gasoline-engine service fall under API’s “S” (Service) categories"

"Oils designed for diesel-engine service fall under API’s “C” (Commercial) categories"

Some people don't know there is a difference between gas and diesel engine oil. I found out when I bought my first diesel (before the first oil change)

 

[Soundguy]

I knew I was getting the designation for S & C wrong.. but I did know s was for gas and C was for diesel at least.. that get me anything?? (grin)

Soundguy,

I'm giving you a big round of applause and respect for knowing more than I did at least!!!! Now I know maybe I shouldn't use Rotella T in my gas engines huh???
