Much stronger detergent and additive pkg than standard car oils (Keeps the engine much cleaner internally including keeping the rings clean) many have additives designed to help condition seals, many more additives to help under high stress conditiond.
If it can keep a soot laden diesel clean for a million miles what makes you think it wouldnt do the same in a Gas engine?
If you look at the oils European Manufactures recommend for 10,0000-20,000 mi drains they all use Diesel Like Add Packages but are more expensive because of high dollar base stocks and low volume sales in the USA. MaxLife type oils basically are overpriced light viscosity versions of Diesel oils maybe with a little Group V Esters thrown in to help with the cleaning (Auto-RX is a consentrated form of this).
Many consider the Mobil Delvac 1 (Group IV) Synthetic Diesel/Fleet oil the finest Extended Drain oil for a gas engine commonly available in the US. But it cost $20-25 Gal and is overkill for your use. BTW They also sell this oil in QT Bottles labeled Mobile 1 Truck and SUV 5W-40.
I have never seen a Diesel Oil that wasn't rated for gas engines. The Fleet on a Diesel oil means mixed Fleet ie Gas and Diesel.
If you are concerned about the weight of the oil ask our Australian friends what weight they run in a 1991 Legacy (They have a differnt name their, cant remember what it is).
The Diesel Fleet oil will also go about twice as long between changes as standard Dino Car Oil.
