Q LIKE David McKenzie (cars­Guide, Septem­ber 17) the fuel con­sump­tion of my V6 Magna in­creased dra­mat­i­cally when I filled it with E10 fuel. I reg­u­larly got 10.9 litres/100km on reg­u­lar, but when I ac­ci­den­tally filled up with E10 it went to up to 14.5 litres/100km. I was so sur­prised I re­peated the ex­per­i­ment and got the same re­sult. When I went back to reg­u­lar un­leaded I got 10.9 litres/100km again. Greg Clarke, Baulkham Hills,

NSW Af­ter David McKenzie told us his TJ Magna used up to 40 per cent more fuel when run­ning on E10 than on reg­u­lar un­leaded we felt we should re­fer it to the ex­perts be­cause his ex­pe­ri­ence con­tra­dicted the ad­vice we had about the fuel. David’s ex­pe­ri­ence con­founded the ex­perts who say it goes against ev­ery­thing they know about the fuel. They say Mit­subishi had no prob­lems with the TJ Magna us­ing E10. We were told that, pro­vided the oxy­gen sen­sors were work­ing cor­rectly, the en­gine man­age­ment sys­tem on the Magna would ad­just for any changes in the fuel. It was sug­gested that David have the fuel-in­jec­tion sys­tem checked by a me­chanic.


Q IN CHECK­ING to find out if my wife’s 1988 Mit­subishi Colt can use E10 petrol I found it’s OK for all fuel-in­jected cars built af­ter 1986, but my wife’s Colt has a car­bu­ret­tor. Is it OK or should we use higher-oc­tane petrol?

L. Man­tle, Wau­chope, NSW Mit­subishi’s rec­om­men­da­tion is for fuel-in­jected mod­els only, so I would not use E10 in your wife’s car. It would be best in your cir­cum­stances to go to the higher-oc­tane petrol.


Q SEV­ERAL weeks ago I no­ticed af­ter gear changes that the mo­tor in my 2009 Nis­san Navara STR 2.5-litre diesel dual-cab was revving. The dealer told me the clutch had burnt out and needed re­plac­ing, and un­less they could find a fault with it, it wouldn’t be un­der war­ranty. They couldn’t find any fault with the clutch it­self. It was just worn out. I have done only 39,490km, mostly on the free­way. I’m a plumber and use the ute for work, but it doesn’t carry a lot of weight. I’ve towed a pop-top car­a­van only twice with it and it’s only been in four-wheel drive twice. I got 94,000km out of my old Mazda ute be­fore it needed a new clutch. I don’t ride the clutch or rest my foot on it. I can’t see what I’ve done to cause the clutch to burn out so quickly. Will I have to re­place the clutch ev­ery 40,000km?

Trevor Poole, email This is not the first re­port we’ve had of clutch is­sues with the Navara. There’s no way Nis­san can claim that 40,000km is ‘‘fair’’ wear and tear on a clutch. That wear rate is ab­nor­mal by any stan­dard. Pur­sue com­pen­sa­tion with Nis­san and think about fit­ting an af­ter­mar­ket clutch that will go the dis­tance. The fac­tory clutches are clearly not up to the task.


QI HAVE bought a new BMW X1 23d and, though I knew it didn’t have a spare tyre be­cause it has run­flats, I was as­ton­ished to find it didn’t have a jack or wheel brace ei­ther. An op­tional jack kit is not avail­able in Aus­tralia. Wouldn’t you thinkBMW­would be aware of Aus­tralian driv­ing con­di­tions, es­pe­cially in the coun­try and re­mote ar­eas where such items are es­sen­tial?

John Wilkin­son, email It doesn’t have a spare so I guess their think­ing is that you don’t need a jack or wheel brace. With­out a spare you

Sur­prise: a reader says his V6 Magna costs a lot more to run on E10 fuel.
