Out of curiousity, do you all think I could run the Mobil Delvac and it would help with oil consumption issues with my 1998 Isuzu Trooper (3.5L V6)?? On the Delvac 1 page, it mentions it helps with oil consumption issues. BTW, I purchased the vehicle new and switched over to Mobil 1 10W30 at about 6,000 miles and since new, the vehicle has used a quart of oil every 1,500 miles (give or take). The vehicle currently has 90,000 miles on it. The rig has been trouble-free, but the oil usage is a pain. Reports from other Trooper owners indicates they are experiencing the same issues with oil consumption. Thanks in advance for any help.
