Hi there Aaron!

Well in 1 of my manuals it states a SAE 60 oil for both the engine and the drive line. Tim Berry passed on this information to me in regards to what type of oil they run in their radial aircraft. And from what he told me it is about 1/2 price to what I am paying for the type of oil I have been useing.

W120 is recommended when the ambient outside temp is 25 celcius on average. It meets SAE - J-1899 and MIL-L-2285. It is an ashless dispersant oil.

Aaron if you are interested drop me a line and we may be able to get it cheaper the more we get.

As for how much you need well for gearbox/diff/final drive you will need atleast 30qts which is about 15lts. Now that for the Stuart so seeing the final drive on the Buff is larger a 20lt drum is probly the way to go.

And when it comes to the engine/air-cleaners you need about the same ammount. So i just got 2x 20lt drums.
