You actually have to be careful and know that there are differences when buying 98...I found out at Caltex - some of their pumps have one sort of 98 and some of the pumps have another....and its a pain when you queue at the wrong one. So my Vespa runs well on one 98 but not the other (higher charged) one...I got a HUGE lecture from the boss about which one his Jaguar likes...and like the Vespa it is also NOT the higher dearer one.,.....and then its confusing because other stations like Shell call them something else again. So this girl has to go and read the tech blurb and figure what is what....<GRRRR>
So if you love your vespa go the 95 if unsure and go the 98 but get the right one!!!....when you get better educated on the differences....Now I won't bore you about engine pinking and all that hee hee!!!
BTW Pete - I can't make it to Patonga tomorrow as have a appointment I cant get out of - but if you go have fun and I'll enjoy it vicariously!
