Spending a fair bit of time over on bike forums- since i have my new baby- 05 CBR600RR.
Really not much to update on PM Lubes- I am in constant contact with them, nowadays distributing for them. Really more than anything they have been increasing the loadcarrying ability of their oils even more, as opposed to coming out with new products. Endurance Lube 25w60 now has a loadcarrying ability unmatched by anything in Australia.
Mate, you want to see the ravereviews its been getting from bike riders- because they have such a high power to weight ratio and high revs to create power, its consistant. Around 80% say they had no idea just changing oil could make such a difference, 10-15% say yes, there is a difference and between 10-5% say no real change. Had so many people write about fuel economy benefits- obviously high revs reduce friction and there is going to be decent gains.
I am keeping up with oil analasys at 6,000k's- first was Motul 5100, then PM- (from memory) aluminium wear rates halved (literally halved), iron down something like 15%.
Diesels love the stuff. Still cant get over them- high torque, low rev engines. Latest was Phil from Highside leathers, if anyone is into bikes and knows him (he is very well known) called me a smartass because he didnt believe it. Now the silly old bugger stocks it himself.
So same old, really.
oh yeah- the US has such a large market, the oils are (generally) superior. However, the issue with same name brand oils in Australia is typically they are blended very differently, but still rely on that branding. Which is where PM and Penrite have been able to make a name for themselves.
....and if your looking for SM, make sure its min 15w40. Anything 10w or below has the reduced ZDP required for the rating
