Is Mobil Delvac the same as Rotella diesel oil? I hear a lot about Rotella but AutoZone has Delvan 15W-40 on sale for $12.99 until Monday, regularly $17.99 for a gallon.

Can I use diesel oil in the V-drive transmission or should I use regular 15W-40?

What is the differences between diesel oil and regular oil? Does Diesel have more zinc in it? Is diesel oil non detergent, and if so what does that mean.

Thanks, Steve
