GOT A PROBLEM WITH YOUR CAR?
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.
DON’T DO IT
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.
NOT ALL RIGHT, JACK
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.
