If you know your whiskey's then :-
5100 - Bourbon
7100 - Fine Scotch
300V - Single Malt
I am sorry I can't think of a better explanation...My bike after years of running on 5100 (30K kms) and 300V (50K Kms) down right rejected 7100. I really did not like the feel of the oil and honestly will prefer 5100 over 7100 since 5100 gives an almost 300V'ish feel.
As The Monk rightly mentioned 7100 is single ester, compared to 300V/5100T which are double ester. The double ester oils tend to leak a little from here and there. But not so much that you will start loosing drastic amounts of oil.
Drain interval on the 7100 is identical to 5100. 300V is not justified for the price its retailing for these days, but then most of the good things in life aren't really 'VFM' (read: Single Malt
) Especially more so for me since I have been using 300V since the days it used to cost 550/- bux a bottle!
