Hello everyone,
Many thanks for your responses.
RichardA and yammick: yes, that was the Mitsi I drove from 2000 for 11 years.
Lovely car; mine wasn't a VR4; that was too seriously fast for me, but my GLS was pretty fast if need be. I sold it to a chap who'd owned one before and really, really liked them. Such a shame Mitsi discontinued them.
Anyway, back to the Honda Jazz. Many thanks olduser1 and culzean; good advice concerning regular oil and filter changes using Honda filters and Castrol fully syn. oil. Will do.
Also many thanks Garyman and saxaphone; bottom line seems to be that there's no Jazz i-vtec workshop manual available yet.
If anyone knows or hears anything to the contrary could they let us know.
Many thanks,
Maurice
