Chevy Express 1500 burning oil

Asked by Jan 20, 2019 at 01:34 PM about the 2006 Chevrolet Express 1500 AWD

Question type: Maintenance & Repair

I have a 2006 Chevy Express I bought new and have religiously changed the
oil every 3k miles…………now I have 120K and having to put 2 quarts of oil
in between changes. No leaks on garage floor and no blue smoke anywhere.
My mechanic wants to do an engine flush, then add 5 quarts of Valvoline
High Mileage Synthetic and a quart of Lucas Oil additive. But, before he
does that he wants to do and engine flush. I am nervous about performing
the engine flush………….anybody have any thoughts ? Thanks.

Have a leak down test performed on engine this will give real information on the overall condition and wear status..before considering a flush and adding Lucas snake oil, causes foaming NOT good.

Skip the flush and the synthetic oil. Try going up one oil weight class. What is your oil change interval?

Auto_Centric: Thanks……..is that the same as a compression test ?

F_O_R: I have changed it every 3K miles since buying it new. Since I don't drive that much, my last change was Sept 1, 2018. Maybe it might just be cheaper to put a quart or two in between changes.
