You're right, definitely nothing to lose by trying...I was at fault for not checking oil level before driving 8 hours, but with a 4yr old and a 5 yr old hyped up on Halloween candy, business calling saying drink station's not working, ex-wife calling telling me not to forget to bring back a single hair bow...well, you get the picture..oil level got pushed to the back burner..I will mention to Isuzu, thanks - Jon
