bit of both really but mainly so as not to shaft the sedona up, the Corsa is currently running on 100% SVO
...not entirely smooth starting but once its going its fine
, serviced it also
next step would be to source some wvo and learn how to filter it properly
the last tank on the sedona managed 550 miles
on the above ratios a few posts up although when my Acetone arrived I shoved some of that in tank had approx .25 left when I added a cap full, previous best was just under 500, make of that what you will
