I use Royal Purple XPR 10W40 in Subaru race car
My wife's TS uses the same
my GD road car uses the 10w30 RP XPR.
RP Max Lube 75w90 gear oil in the diffs and the gearboxes
RP purple Ice in the radiators.
using RP close to 10 years now, do not have a single complaint.
if you are unsure as to what oil to use call the guys at Rooks Engineering, they are the distributors.
They will help you
