Winter Oil

[Mr. Pistachio]

Hey Deli fans!

For you folks who drives in winter conditions, you already know but just to share another experience, winter oil (0W-40) is the shit. It make such a difference when it's bloody cold outside. As for brands, that's up to you. I run Rotella, was on the only affordable 0W-40 at CT. Mobil1 was 10$ more and at that price range difference is minimal. That's my 2 cents!

I don't know about Rotella and its molecular makeup (I looked on the website/called Shell and they would not tell me if it is PAO or ester based or for that matter the zinc and phosphorus contents, of course Mobil has that stuff on their website in plain view!). I Use Mobil 1 Turbo Diesel Truck, also known as Mobil Delvac 1. 5w40 is good to at least -30 deg. C. and is also great in summer. Below is report of comments I made before:

Mobil 1 PAO molecule based oil is superior to esters (such as Redline and Royal Purple, and numerous oils such as the one marketed by Top Secret in Japan <WAY OVER PRICED>). However, ester based oils are not bad, and certainly better than regular oil, but just not as good as PAO's like Mobil 1.
AND DEFINITELY AVOID CASTROL SYNTECH!!! I read the reports and the court case documents that resulted from the lawsuit over the definition of the synthetic molecule. Castrol's definition of a synthetic molecule is seriously WRONG!!!

I like to run Mobil 1 5w40 Turbo Diesel Truck in my gasoline 4G64 powered L300 (we never got the diesel in the USA). This is the same oil that big-rigs use, but is approved for mix fleet use, meaning it is fine for gasoline.
Also, M1 TDT has a higher content of the anti-wear additives, phosphorus and zinc. The levels used in M1 TDT are the levels that used to be used in all the Mobil 1 range, before the Federal Government (USA) made them lower the levels to help preserve catalytic converter life (in gasoline cars).

I did a lot of research into oil; there is so much biased information and personal opinion on the Internet, it is hard to figure out anything. No, wonder you have guys just saying things that sound like repeats of the ads they read in car magazines!!!

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).

Goes both ways bro. Your posts sound like repeats as well. Everyone's does because everyone has their own source of information and their own personal opinion based on their experience. Use what you think is best. There is enough information out there to make your own conscious decision.

Bottom line. The Shell Rotella synthetic (in the blue bottles) at 0W40/5W40 is one of the best synthetic oils for north american climates (wet and cold) in my opinion based on personal experience over the past 20 years of driving in BC and from diesel owners that I know. It's used by long haulers, excavators, cats, pipeline generators out in the field and consumer vehicles (like ours).

This is also one discussion that will never end as opinions will always differ.

I know it's an old post, and found it when looking for an answer.

The question: I have used Delvac 0w-40 in the past and was told that I could go for 10k before changing.

I could not find Delvac and just picked up some Rotella 0w-40 and was wondering if anyone has an opinion on appropriate milage (kilometreage doesn't sound right) for this stuff (expensive, but if you can go twice as far than not so bad).

Anyway thanks for any input,

Darren

you'll get varying responses but the rule of thumb is 5k.

What I figured. Thanks

Well since this old post got dug up I thought I would share that CT has 25% off Rotella T 15W-40, 5W-40, 0W-40 right now in the 5L jugs. $30 instead of $40.

I think its on till Nov. 10th.

I need to buy three. 12.5 liters + 2 filters, all the pennies I can save for every oil change.
