If i remember correctly a few years back ford introduced a plan to retrofit a lot of thier auto's to run peanut oil instead of water/antifreeze in thier cars. this is all from memory so please bear with me, but it kept the engine about 30% cooler and also only needed about 1/3 the amount of fluid. This is currently why porsche oil cools. better cooling hence less wear and tear. I was curious if anyone has tried peanut oil since it's properties are way better than what most currently use for heat transfer. I'm 100% serious here guys so please dont take this as a joke post. oh yeah the reason i've not tried yet is because i'm still working on my first water cooled system
