| I have changed over ALL the fluids now. I alternate my oil filters every so often, but normally stick with AC Delco. I use the Allison spin on filter and change it every 35,000 miles aside from the 2 flushes. I use an AFE fuel filter though. I also changed my front dif axle, my rear dif axle, my transfer case and stick with sythetic on each and every oil change. So far so good! |
