Fuel se­lec­tion a con­fus­ing is­sue

NT News - Motoring - - CARS GUIDE -

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.
