Where I bought my truck, the dealer does ALL the routine maintance per schudle A in the owners manual. So I can get my oil & filter changed every 6000 miles free.
I have been changing it every 3000 & take it to them every 6000.
NOW, my question is... ... ..... They use Mopar 15-40 oil, and I have been buying it from the Dealer for about 25% off list. Still kinda expensive! I hate to use different oils between changes. e. g. The dealer using Mopar oil & me using Rotella or something else.
Should I continue just buying the factory Mopar oil (which isn't that expensive with the discount). Or would you guys just mix oil between changes, with whatever is on sale
