I ended up using a Torco RGO (racing gear oil) in my kaaz 2way, which is a 85w140 and also a torco friction modifier (type F) to eliminate the chattering. Works a treat! also when your changing the oil every 6 months or so, it ends up much cheaper than buying the kaaz stuff

any gl5 75w90 and change it every 2-3 events. rotella is fine. there is no need for super expensive oil, however for best results add a bottle of FORD friction modifier to each oil change. i ran that bitch for 2 years and it locked perfect every time. no need to waste money that you will flush anyway.

how much fluid do i need to pick up for my diff? does it take more than 1 quart? i thought i used 1.5 before. should i pick up 2qts just incase?

Kaaz oil or equivalent, 75w-90 if its your daily. 80w-140 if youre tracking.

Obviously the KAAZ fluid is ideal. But it's also $50+ per can.

I used Castrol Hypoid-C 80W90 mineral gear oil and a bottle of Motorcraft (Ford) Friction Modifier. Works out to be around $20 per change.

KAAZ specifies mineral oil instead of synthetic. Capacity is about 1.5 qt. I changed mine every 2-3 track events and it always drained clean. If I were daily driving it, I would change it with every engine oil change.

Damn this thread is old but I'll add

Owned my Kaaz 2 way now for about 10 years(S14, 4.08, w/high-capacity Greddy diff cover so it's about 2.4L of fluid), changed fluid every other oil change(so about every 6,000 miles of driving), making sure to use NON-SYNTHETIC 80w-90 gear oil and bottle Ford friction-modifier.

I usually end up using Valvoline since I can find that in a 4Qt/1 Gallon size. Having the extra-capacity diff cover made it challenging to find that Kaaz gear oil is so expensive and basically doubled the cost if I bought/used Kaaz oil. I have found 0 issues with my choice of oil in my diff and it's operations in past 10 years.
