sco, I think part of the problem is that people read the US and Aus sections almost interchangeably, but the conditions are quite different. And I'm not sure it's right to be running 5W20 in Las Vegas or Phoenix in summer, vs Chicago or Detroit, in winter

Funny isn't it how people believe dyno figures without question,but not manufactures figures.A dyno is only useful to compare mods from a baseline figure.If you go to 5 different dynos,you will likely get 5 different figures,with some large variations.
I have seen cars gain 25+kw at the wheels by going to a different dyno a month apart.
Performace figures recorded by magazines are consistent with Mazda's claims.

Pistons, yes. Rotaries, no
Must I type the Curtis Wright engineering paper to prove this....??

Hey, has anyone tried mixing ethanol with premium to reduce fuel costs? Wildcard, see if you still run OK on that!

Just excuse me while I struggle out from under this diamond encrusted desk and go pee in my solid gold dunny.
Meanwhile, there's developers and 'consultants' starving in the gutters. Humph, hope they don't dare begging from me on my way to wherever Charles is waiting with the Bentley.
