After all the reading through the posts I'm thinking of trying some Elf 5W40 in my NA8 engine.
But from looking on their site there seems to be a range:
SOLARIS LSX 5W40
EVOLUTION SXR 5W-40
EXCELLIUM XLL 5W-40
EXCELLIUM FULL-TECH 5W-40
EXCELLIUM NF 5W-40
EXCELLIUM SM 5W-40
Only one I have found for sale in Perth online is the Evolution SXR for $59?
Just then I thought I had figured out which brand and viscosity I was going to choose, this throws another curve ball in the decision making.....
