Dealer suggested a BG oil additive at my 30,000 mi Maint 2 service. Is this necessary? It is $25 above the standard oil change which includes a 4 mo road service. Already have AAA.
Oil additives on 2007 Buick LaCrosse
i dont believe in any oil additive. oil has all the additives it needs already. i would stick with your schedule as you normally do.
