apprently 10w-40/15w-40 is recommended for RB's?
narrowing it down to these 2..
Penrite Sin oil 15 15w-40
elf competition GT 10w-40
currently using mobil 1 syn-s 10w-40 and afaik isn't available anymore & has been replaced with another name, mobil 2000 or something.
gonna change to fully synthetic to either one of the above mentioned ones.
car is due for a change in a months time so see how it goes then.
ive read that with the full synthetic oils, they still stay the gold colour after 4000km.
with the current oil im using, it starts to change colour after 2500~km, im guessing the oil im using isn't that good?
any opinions with the 2 oils ive chosen ?
wheres the cheapeast place in syd to get either of the 2?
cheers
