Depends on the brand, if so and how much(they hardly give the additives used). Zinc is an "anti wear agent" especially it's extreme pressure qualities which aid in reducing piston ring-to-cylinder bore wear at BDC and TDC. It also protections from oxidation/corrosion. Almost all diesels oils have it in them.
15 is thicker oil and for bigger engines.

Gas engines use 10w30 diesel uses 15w40
Gas engines use 5w30 or 10w30 Diesel uses 15w40
The gas engines use 10W30. The diesel engine uses 15W40.
Gas engines use 10w30 Diesel uses 15w40
Only the weight of the oil, 20w 40 is thiker than the 15w40, 20w 40 is the best oil for the old cars although 15w40 is very easier cold start ...
15W40
15W30 and 15W40 are commonly used, oil specifically for diesel engines, and API CJ4 requirements for newer trucks.
The Ford M2C-41-A is the nomenclature given to engine oil that is used in Ford diesel engines . The SAE equivalent is SAE 15W40 to be used in diesel engines, and 20W50 to be used in gas engines. Each manufactuer gives its own names to oil. All the different oils, however, are the same.
I had an `86 5000S (Gasoline model). It used SAE30 as I recall.AnswerI would personally use 10w40 or 15w40. I concur with 15W40, my mechanic tells me to put 15w40 because it is thicker and older engines which are worn make it easier for oil to pass through and thus your oil pressure is low. 15W40 is Diesel engine oil but will not harm your gasoline engine, i have been putting it in my 1989 100CS quattro for years now and it runns better. For colder Canadian winters (-40C) I use 10W30 so it will turn over better when cold.
15w30 or 15w40 are common for "all around" usage. Make sure it's oil specifically for diesel engines.... API CJ4 is mandatory if you have a more recent model with Selective Caralytic Reduction, and is compatible with earlier Diesel engines.
