Fuel selection a confusing issue
The previous owners of our 2006 Mini Cooper had been using regular unleaded while the Mini manual recommends 95-octane.
As a test I drove 120km in the country with regular unleaded still in the tank and averaged 6.2 litres/100km.
Then, with the tank almost empty, I filled up with 98-octane unleaded for the identical return trip, on which it did 6.1 litres/100km.
As there was no significant difference in economy using 98-octane fuel, is it safe to keep using normal unleaded petrol rather than the higher-octane blend? Is the 94-octane 10 per cent ethanol blend a better choice because of its higher octane rating than standard unleaded?
Mini says the Mini Coo- per is suitable to run on E10, which is cheaper than regular unleaded and has a higher octane rating. That’s the way I would go.
I recently got in touch with the RACV regarding putting my 2008 Holden Caprice on gas and was told that because I do 12-14,000km per year, it would take me too long to recoup this outlay.
But I read in Carsguide that it would be OK. Mine is a sixcylinder Caprice and I would have a liquid-injection system fitted.
My 2006 Ford Territory has had the front suspension ball joints replaced.
Are you able to advise if the problem with the ball joints can be fixed by the simple addition of a grease nipple?
Has Ford produced a retrofit modification?
Has the warranty on these ball joints been extended?
Has the problem been overcome on later models?
Will the launch of the new Territory see the end of the problem?
It is possible that the problem could be fixed with regular greasing, although no one to my knowledge has tested it. There is no retro fix. Ford’s fix was to replace the ball joints with new ones. There is no change to the war- ranty. The problem was addressed with the update in 2009 and it seems to have done the trick, as we haven’t had any more reports since the revised front suspension was introduced. From what we can see, the problem has been fixed.
My 2008 Holden Viva wagon is due for its 30,000km service and the Holden dealer has quoted me $330.
Ultra Tune have quoted $196 and stated that they would do the full logbook service. If I give the work to Ultra Tune, willmywarranty be voided?
No. Holden can’t void your warranty should you use another service agent; just make sure they are going to do the logbook service as they claim.
