Schaffers 722 and 711 is on the recommended list but I found next to no info from people running it in there 6.7’s. Most people are running schaffers 9000. Looking for feedback on the 722. Run it? Run something else? All that’s been in the truck is motorcraft 10w-30 and looking to switch. 2017 F350 KR dually on weight loss.
