Yup, went to Wally World today, and there they were! 1.25 gallon jugs of it for $19.88. That's $3.98 a quart. I'm in!

 

Finally; thats good news. I just picked up 3 gallons the old fashioned way last weekend ......

 

I've seen it in a Super Wal Mart in IL, but not in my local Wal-Mart. At that price there's no sense bothering with the Rotella T "synthetic".

 

I just paid $22 per gallon from local distributor. Maybe have to stop at Wally World a little more often.

 

Is it certified for diesel use?

 

Mobil 1 Truck & SUV is repackaged Delvac 1

 

So it's a fully synthetic oil? Would this be better than the Rotella synthetic? I have been told that the Rotella isn't truly synthetic.

Yes it is (Mobil 1), and you were told correctly.

 

I don't want to start another Oil War...but if the Rotella synthetic is a group 3 base oil (i don't personally know) than it would be unfair not to call it a true synthetic. It's a newer and less expensive version of the better known PAO (poly-alpha-olefin) but there is nothing wrong with it, IMO.
I don't use Shell and am not a big supporter of Rotella in the last few years but.....

On the other hand, I do not see how Mobil can sell what use to be Delvac I for $4.00 @ qt??? The Delvac I that I know from the past can't be manufactured and distributed for $4.00 @ qt! IMHO.
Also, Mobil has gone to using their tri-base oil in many oils, incl. Mobil I. It's a combination of Group 3,4 & 5 base oils and no one I can find can tell me what % of each is used. Nothing really wrong with this, in normal applications, but not what it once was for Racers or heavy users. Could Delvac I have been reformulated??
JMO base on 15 yrs being involved in Mfg. of higher quality lubricants.

I looked at the Mobil website and the Mobil 1 Truck/Suv and Delvac 1 have exactly the same specs. I don't know about the other stuff.

As far as I know Delvac has always been a group 3 oil.
Not a true synthetic but can call it synthetic due to goofy laws.

 

I was unimpressed this winter with the cold pour characteristics of the Valvoline Blue extreme 5-40. I run synthetic oil mainly because my truck has to sit outside in Minnesota winters but the Valvoline left me wishing for a true synthetic.

I might give the Mobil 1 a try and see if it is any better if I can get it at that price.

 

Bill, I may be wrong but I thought Delvac I had been around a lot longer than the use of Group 3 base oils, so I assumed it was a PAO (Group 4). If it's Group 3, that would explain the lower pricing...but not the devout followers who swear it's the greatest.

amartinson - if looking for the lower pour points of a "true" synthetic, using Group 4 or 5 base oils, I would suggest Amsoil. (and maybe Royal Purple and Red Line....not sure anymore about these two.). Amsoil is the only Mfg. I know that has doggedly stuck with group 4 and above. It will only gain you about 10-20* difference, in the pour point, from Group 3 oils, which may not be noticable in cold startups.

It isn't if you can believe this taken from the bobistheoilguy site:

Mobil1 Truck and SUV 5W40 and Delvac1 5W40 are slightly different in formulation which is considered proprietary. Mobil currently does not have any plans to reformulate the Truck and SUV to meet CI-4 Plus."

 

Actually Delvac 1 is of the highest quality, and is in fact a group 4 pao/ester based true synthetic. Amsoil is group 4, as well as Redline. Some popular group 3's are Rotella syn, Valvoline Premium Blue Extreme, Castrol Syntec(gasser), etc.
