I used to work with an old man at a tractor company. He was into cars back in the day and broke them down, tinkered and raced them occasionally with his buddies. He was telling me that they (him and his buddies) mixed an oil that had zero weight by mixing Marvel mystery oil/diesel fuel 50/50 to put in an engine. I thought about this for the longest time. I have never used either cause I don't drive a huge truck or need to purchase mystery oil to revive lack of power ... So my question is "Has anyone tried this?" It sounds great... 0 weight so the engine isn't pushing/fighting with oil so much to lubricate?
