About once every 2-3 months I travel about 30 miles to a town to do some shopping and go to a truck stop. They sell Shell gas and I tank up on V-Power 93 octane and run that down to about a quarter tank left before I fill up again on Exxon 87.
This is the same exact stance I take. Name brand fuels are the way to go, and no need the bump the octane up if your compression and timing don't cause it to knock. I drive a 1968 c10 short wide with a 350(installed in 1974) and a quadrajet(gen 2) carb. The engine and carb were rebuilt in 1984 by my father, and it has almost been driven every day by one of us. My dad gave me the truck in 97, and I'm currently driving it every day. That's 25 yrs on hone only rebuild with new bearings. Just replaced the head gaskets, and the valve guide seals about 6 months ago, and rebuilt I the carb with a kit. True miles are unknown, due to the speedo being out of service for about ten yrs, bu a realistic number would be over 250k with only one fuel system failure. Was a fuel line that turned to gum after about 7 yrs of e10. 4$ 10min fix. I have never used warehouse gas, or additives. Dino all the way at 3k, and cheapy filters. Based on my test truck allot of these products, and practices are hard to swallow. But I guess back in the 60s engines were all built like ak47s. Our 97 jeep gc 4x4 gets the same fuel rules, but all the other fluids and filters I go nuts over.
