Up until a little over a year ago I owned one vehicle, a 99 Buick Lasabre that now has 99,450. I average about 3400 miles a year and my daily commute to work is 1.6 miles one way. Lets put it this way, the town I live in fits easily into six square miles so every where I go is a short trip. I always considered my vehicles were under sever duty and change my oil every 3 months (I know old school). For the last few years I've been having a privately owned quick lube do my oil changes, an old bar buddy works there and I trust him plus they use a Valvoline blend I think. The only down side is the Valvoline filters are probably on the low end of the scale but always figured they were good enough as long as I stuck to my 3 month changes.
A little over a year ago I inherited a 1989 GMC Sierra from my father in-law with 12,000 miles on a new crate 350. I have been driving them equally as much as possible which brings me here wanting opinions, how often would you change your oil if you were in my shoes?
I don't want to use a full synthetic in the Buick but might consider it in the truck since it has lower miles on the motor, plus I'm not sure he has bulk synthetic. He only charges me $34 a pop with my $2 off local high school discount card. He said I could bring my own filter which will make me feel better. I can get the Carquest blue at AAP for cheap with their discount codes.
