Looking to buy some 75w90 for a Ford 8.8 with a clutch style limited slip. In the years past I've used all kinds of cheap stuff, supertech, stp, valvoline white bottle, valvoline synpower (I don't consider that one cheap quality but the price sure went up the past few years) etc. I noticed the Triax 75w90 in a gallon on Amazon for a good price, seen several threads on people asking about it without anyone really saying anything about it that's actually used it. I've got about 11,000 miles on this axle after 2.73 to 3.27 re gear and posi install and want to change out the supertech 80w90 conventional I put in it for break in. Looking to keep it somewhat cost effective, what are yall's recommendations? I'm interested in buying 1 gallon container up to a 5 gallon pail.
