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 15W-40 Diesel mineral oil; 2. 2015 Subaru Forester Turbo, currently on 5W-30 Mobil-1; 3. 2008 Toyota Tacoma 4x4 2.7 Liter 4 cly.,-recently changed to Mobil-1 TDT 5W-40; 4. 1996 Toyota Camry V-6 345,000 miles - Mobil-1 TDT 5W-40, 5. 2006 Kubota Diesel tractor - currently on Chevron Delo 400 diesel oil; 6. 1951 Plymouth - 5W-40 M-1 TDT; and 7. 1949 Dodge 3/4 ton - M-i TDT 5W-40; 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 0W-30 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 TDT 5W40 be about as good as I could do? I notice it is certified for use in both diesels and gas engines.
