Mobil 1 ESP 5W30 and Delvac 5W40 are right next to each other at Walmart and usually within a dollar of each other in price. Our 2 cars use Mobil 1 ESP and my diesel Jeep uses Delvac 5W40. Both are good oils, so I think it will just be your personal preference. Blackstone tests will tell you the story on your oil and intervals better than Reddit.
Mobil 1 Turbo Diesel Truck 5W-40 in an ALH since new. 10K OCI, engine with 280K running like new.
Mobil 1 ESP 5W40
I run rotella t6 5w-40, and she loves it
Mobil1 is great oil and what I personally use.
One of my cars has 240,000 miles and burns 1/2 a quart in 10,000 miles using Mobile 1 5W-20
10w30 Rotella will cut your oil consumption by 70-80%, ran it in my last Subaru until the clutch went at 234k and running it in my current Subaru
Change the oil with Rotella T6 oil.
All 4 of my Subarus have serious consumption problems with Mobil 1. On my current 15 outback I tried liquid moly and it consumed it. I went back to the Subaru dealer parts department and so far 1200 miles the level is still full.
Yea mobile 1 is among the bottom end of full synthetics. Even the Walmart cheapest supertech and valvoline will slightly beat mobile 1 in reducing metal wearing.
