I like the Shell Rotella T6 that I believe FCA is using on the EcoDiesel's now, but I see two other oils that I could go with from Mobil 1 at WalMart: Mobil Delvac 1 ESP 5w40 & Mobil 1 Turbo Diesel Truck 5w40. Big difference in the tech specs (from M1's website.) The Delvac 1 ESP has the new CK-4 formulation, which apparently supersedes CJ-4. Thoughts/comments?


Mobil Delvac 1 ESP 5W-40
engine oil meets or exceeds the requirements of:
API CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4
ACEA E9, E7
Caterpillar ECF-3

Mobil Delvac 1 ESP 5W-40 engine oil is approved by the following OEMs:
Detroit Fluids Specification 93K222, 93K218

API CJ-4, CI-4 PLUS, CI-4, CH-4/SM, SL, SJ

That's why Delvac 1 costs $45/5qt and M1 $25/5qt.

Actually, the Turbo Diesel Truck comes in 4qt jugs. Looks like the new Delvac 1 ESP is superior with the CK-4 rating. PepBoys has it for $30.99 a 5qt right now, with free shipping if you buy two. Apparently Rotella T6 will have new CK-4 rating as well, but I can't find any specs on what they did for CK-4 like M1 has provided.

Would you use Delvac 1 5W40 in a gas engine?

I'm pretty sure the Delvac 1 ESP is intended for just for diesel.

Thanks for the link. Mobil states at the bottom this oil is ok for gas engines.

One thing that has me concerned is the low viscosity cSt @ 40C for the Delvac 1 ESP 5w40, every other CK-4 5w40 is in the 90's.

Applications
Mobil Delvac 1 ESP 5W-40 is recommended for use in all super high performance diesel applications, including modern low emission engine designs with Exhaust Gas Recirculation (EGR), Aftertreatment systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). These applications include the following:

On-highway engines operating in both high speed/high load and stop-and-go conditions
Off-highway engines operating in severe low speed/heavy load conditions
Virtually all diesel powered equipment from American and European equipment builders
High performance gasoline engines and mixed fleets--------------------------------------Seems not exactly so.
Refrigeration units

I don't see anything wrong with that, it just pumps easier at colder tempertures. I prefer that in the cold for my Cummins winter starts.

Pretty sure Garak's G37 is not a diesel ... just wish D1 products sold for less ... Think what you see in Mobil products is you will pay for PAO ...

I'm pretty sure the Delvac 1 ESP is intended for just for diesel.

I use it for a gasoline engine, as was already pointed out, and I'm not the only one.

With regards to the CK-4 Delvac 1 ESP 5w-40, it does seem to be "dumbed down" a bit compared to the CJ-4 version. Pour point is higher. Flash point is lower. This seems to corroborate, however, that the previous versions were more "ringers" in their category, more than saying anything bad about the current version. The current version will still perform identically for over 99% of people using it. It will be completely seamless, except perhaps for those pushing OCIs out to the limits. Then again, TBN has climbed a bit and we do have the CK-4 improvements, so maybe not. For cold weather, the numbers are fairly typical for the grade.

With respect to pricing, the situation up here is reversed, because big box retailers up here cannot be trusted to have sensible margins. I get Delvac 1 ESP 5w-40 for about $25 a jug directly from Imperial Oil. M1 TDT 5w-40 goes for over $50 a jug.

Around this neck of the woods, Rural King has it for $21.99 for a gallon, they also have the 5 gallon bucket. Meijer has it for $22 a gallon. Advance Auto is selling it as well, but, it is more there, I think around $30 a gallon.

Both are of good quality but looks like Delvac 1 is better. If the price difference is not an issue then why not go for it. It looks promising and read somewhere that it is recommended by most truck drivers.
