Is Walmart Mobil 1 Turbo Diesel same as ESP 5W40?

I installed OPS system with Mobil Delvac 1 ESP 5W40, which is about $39 per gallon at truck stops.

I have found it at Pepboys for $28/gal.

Also see at Walmart Mobil 1 Turbo Diesel Truck 5W-40 at $27/gal.

Is this same/similar to ESP?

Any other sources for most economical oil?

Both products have different formulations and both exceed API CJ-4 requirements. Either product, however, can be used in your particular engine. Mobil 1 Turbo Diesel Truck 5W-40 is specifically formulated to provide outstanding protection to light-duty diesel-powered passenger vehicles. It also exceeds the requirements of API SM classification for gasoline engines. Mobil Delvac 1 ESP 5W-40 has been especially formulated for use in all super high performance diesel applications, and has engine builder approvals for the following: I would feel better myself using Delvac 1 ESP 5W-40

I also started out with ESP 1 Mobil delvac, it is hard to find, and expensive.

I go to Carquest and they have the store brand that matches the same standard as the Mobil

I also agree with cdowning, you can find less expensive oil that meets the manufacturers standards

How about it Ms Hill, you agree

I have been getting a Delo 400 LE 5w40 full synthetic at Wally World for $19.98 a gallon for some time. Just ordered a few more cases from my local Walmart. It is a Group IV oil like Mobil. Virtually the same cold weather flow point. Have had very good used oil samples from it.
