Where I bought my truck, the dealer does ALL the routine maintenance per schedule 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 Castrol 15-40 oil, I have priced the Castrol 15w40 at AutoZone @ $2. 79 a quart=$67 a case. I can get Rotella 15w40 at Samsclub for $48 a case of 6 gallons. My dilemma is to use cheaper Rotella, when I change it & let them use Castrol. I hate to use different oils between changes. e. g. The dealer using Castrol oil & me using Rotella or something else.
Should I just buy the Castrol Or would you guys just mix oil between changes, with whatever is on sale?
I am 57 with bad knees & back, I can change my own oil, but it's kinda hard on me. Also I can find Rotella anywhere, Castrol 15w40 is hard to find!!
