I'm also interested in the difference with the new Delo 400LE.
FYI, this was taken from the caltex website.
This seems to be the difference between the 'older' Delo 400 Multigrade and the 'newer' Delo 400 LE

So, am I right in saying that it looks like the 'older' Delo 400 multigrade seems to be a stouter oil than the newer Delo 400LE, however the new LE has less ash?
BTW, is sulfated ash an issue with motorbike motors, specifically newer fuel injected sportsbike motors?
Also, isn't higher zinc better for motorbike motors or am I just way off track???
Cheers,
Dan.
