Granted, these formulations have been out for some time, but...

Delo XSP 15w-40 - Looking at the PDS:
  • Published pour point is much lower than Rotella T6 and Delvac Extreme, 15w-40s. On par with 5w-40s. Are they not using the ASTM D97 method?
  • Cold crank viscosity of 4600 (-20 C) agrees with the above - Rotella and Delvac are 6300/6100. (Are they not using ASTM D5293?)
  • The 40 C viscosity is in line with the other 15w-40 full syns.
  • If the differences are real, what does it tell us? "Better" base stock for a 15w40 that performs better at extreme cold?

Delo XSP 5w-40 - Looking at the PDS:
  • HTHS is higher than that given by Delvac ESP. (Rotella not publishing HTHS.)
  • If the difference is real, what does it tell us? "Better" base stock? (Was the AAP clearance sale a really great deal after all?)

Yeah, I'm thinking I shouldn't have sold so much of what I had gotten. That said comparing the stats of both the 5w-40 and 15w-40 to the peers from Shell and Mobil, they just look a little different.
 
I’m going to be using it in my truck at my next oil change in about 5,500 miles. I picked up 6 gallons during the aap clearance as well. It seemingly has the highest (published) hths out of the 5w40 diesel oils.
 
I bought two pails of 5w40 Delo in 2020 and still have about 28 quarts left.
My son just bought a 2012 F350 with the 6.2 gasoline engine. I’ll give it to him to use up before it goes bad. He’ll get 4 oil changes out of it.

I've used XSP quite a bit in my tractors and now in my GX. There is an absolutely jaw dropping stellar UOA that someone posted for their Scion in the forum section.

There is a current rebate available which makes it cheaper. Pay attention to the dirty details though, max $25 per rebate submission, so you may need to split up purchases. I'm going to buy some later in the term.

The thread starter was discussing XSP 15w40, not the AA clearanced XSP 5w40, but you probably didn’t catch that?
Honestly, I was looking at the PDS for both, as they each have some facet wherein they’re a little different from the competitive equivalents.
 
Same question as I asked previously with the last gen product:

just did the rebate thing.. you gotta get 3 gallons at a time on a receipt to get the 25 bucks.. the info says 10 per gallon... or 25 for 3.. there is no way to do rebate for single gallon on the online rebate form.. I had gotten 2,, all they had and had to take them back to get 3 on one ticket. might get 3 more at last day to get another rebate.. :)
