nothing wrong with diesel oil if its made for modern day engines (like it says). it does have detergents in it tho (well diesel oils used to anyway) i see no problem with running it. i just dont like penrite.
the oil i use in my car is full synthetic oil we use in the new diesels with particulate filters. tho on the bottle it doesnt say its just for diesels.
a diesel is under way more load than a petrol motor. but petrol motors run hotter.
