Diesel Engine oil question

[MacDaddy67]

Normally use Rotella T6 15W40 in my Cummins.....since it is hard to find now and ridiculously expensive...thought about switching to
Mobil Delvac 1300 Super 15W 40

Says its a synthetic blend......

Anyone use it or have any insight?

No feedback on quality, but I just put it in my Ram 3500 and Bobcat. It was like $12 per gallon at Walmart.

Probably made at the same place.

I use 10-30 delo diesel oil in my power stroke have for years, have youse the delvac also. Don’t think it really matters.

Same here, thinking about going with the T 5 Blend. Same brand.

I run Mobil 1300 in everything in my fleet and have been using it for years. Its good stuff.

Just changed the oil in my 2019 6.7 CTD. I used Rotella T5 10W-30.

I’ve stuck to Valvoline Blue and Fleetguard filters in my 2015.

Honestly, I would stick with what the maker of the vehicle recommends, that way if something goes wrong and you used the oil recommended by the vehicle maker, you have feet to stand on if something goes wrong. Ask me how I know something could go wrong.

I’ve ran Rotella T4 and earlier jugs in my 7.3 P/S since 2001. Just bought 12 gallons for $185 shipped today.
