I don't doubt anything anyone says based on years of experience, but when it comes to what is "best" for anything is a very random question and has no clear cut answer. If you have been building race trans for 30 years, always used Type F and never had many problems, sure, you can claim that the best. Same with cams, intakes or anything else............but this is 2016. Hard to fathom that a very basic oil from the 60s and earlier, is the absolute BEST fluid you can put in a race trans. Why aren't we all still running straight 30W Quaker State for oil. Or "mushroom" cams, pinion snubbers, casler tires or anything else that was the BEST in the 60s.

Like I said, Type F will work and obviously many still use it. I only said there was better fluid and I believe that
