Oil - Brad Penn semi-syn 10W30...one of the few brands out there that still has a ton of ZDDP with no additives needed or recommended...critical for flat tappets IMO. Modern SM rated oils can really hurt these motors IMO... Power steering- I have no idea what is in there LOL... Brakes- Dot 3, generic auto store on sale Rear differential - Conventional 80W90 Pennzoil (cuz it's cheap) with a bottle GM slip additive for the posi. Transmission - generic auto store dexron on sale Additives - Other than the GM Posi additive, I run nothing but pure fluids...except some StarTron Ethanol fuel stabilizer in the last gas tank of the summer mostly for storage purposes. We have had 10% Ethanol in all fuel here for about 20 years running...never found nuthin' wrong with it. Antifreeze - Peak 50/50 extended life, cuz its cheap & always has rebates. Chassis grease - whatever's on sale
