Hi,

Just bought a second hand (made in 1999) GMC Savana 2500 6.5 liter turbo diesel cargo van. Driven 196,000 miles... Now I plan to change the motor oil (15W-40), but donīt know which mineral oil to pick...I donīt dare to use synthetic oils as I donīt know the previous oils used in this van - there is no service book left...

I was thinking of Kendal Super-D 3 15W-40 or Gulf Oil Super Fleet Supreme 15W-40...


Do you think that Mobil DelVac MX ESP 15W-40 would be better or worse than those oils listed above?

Thanks a lot for your help.
