Mobil 1 TDT 5W-40

[SargeBB]

I'm moving towards a common oil for all our vehicles: Here's some information on each, including the current oil used on each: 1: 2015 Ford F-350 6.7 Diesel, currently on Motorcraft 15w40 Diesel mineral oil; 2. 2015 Subaru Forester Turbo, currently on 5w30 Mobil 1; 3. 2008 Toyota Tacoma 4x4 2.7 Liter 4 cly.,-recently changed to Mobil 1 Turbo Diesel Truck 5w40; 4. 1996 Toyota Camry V-6 345,000 miles - Mobil 1 Turbo Diesel Truck 5w40, 5. 2006 Kubota Diesel tractor - currently on Chevron Delo 400 diesel oil; 6. 1951 Plymouth - Mobil 1 Turbo Diesel Truck 5w40; and 7. 1949 Dodge 3/4 ton - Mobil 1 Turbo Diesel Truck 5w40; and our many mowers, generators, power washers and other air cooled engines run on the various viscosities of old Mobil-I I have in stock ranging from 0w30 to 15W-50, and they all run very smooth on it.
Finally my question: If I get ALL 7 of the above on one common oil and viscosity, would the Mobil 1 Mobil 1 Turbo Diesel Truck 5w40 be about as good as I could do? I notice it is certified for use in both diesels and gas engines.

I can't comment on what would be the best, but Chevron Delo 400 XSP Synthetic 5W40 also carries the API SN rating for service in gasoline engines. It costs less too.

Yes, this! A thousand posts lament the loss of SN rating on Rotella T6 and nobody seems to know this SN Delo Syn exisists

I would keep the Forester seperate with 5-30 but go ahead with the Mobil 1 Turbo Diesel Truck with everything else, or buy a SN rated 5-40 HDEO on sale, or save even more by buying by the pail and using the Mobil rebate. Mobil Delvac 1 will be SN rated when the new stock arrives.

Another vote for the Delo for the entire fleet.

Does delo or Mobil 1 Turbo Diesel Truck meet the Ford spec for the 6.7? I couldn't find anything that says they did.

I cast a vote for Rotella T5 10w30.

My T6 in the sump still has an SN rating, along with CK-4.

5w30? As in the title of the post...we are talking 5W-40, Mobil 1 Turbo Diesel Truck, Delo, etc.

Mobil 1 5w30 isn’t typically awesome in turbo Subarus.

IIRC ... Delvac 1 ESP 5w40 is around 30% PAO and 12 TBN … and seems Mobil has to be careful not to compete with Mobil on approvals … but know folks who run in new PSD’s regardless … couple times a year Walmart will have on sale but expensive when it’s not …

True, but it still has a whack of diesel OEM approvals. Nonetheless, let's look at Rotella T6 5w-40 CK-4 (or any HDEO 5w-40 that recently lost gasoline certifications). If an E7, E9 5w-40 HDEO was suitable for your gasoline engine a few months ago, what makes that E7, E9 lubricant unsuitable for the same gasoline engine a few months later?

PAOs aren’t listed on the new SDS for D1. It says it’s group III and GTL bases now. TBN is now 12.
