The Mercury Cars Guide : December 12th 2009
12--- Classifieds 62 300 400 • carsguide.com.au Saturday, December 12, 2009 Frustrating battery problem fixed ANY IDEAS?: Help for a niggling noise problem in the Mazda6 sought. email@example.com with GRAHAM SMITH Q WITH respect to the reports you've had about the battery going flat in the VE Commodore we've only seen a couple of problems at our dealership and these have been recti- fied by Holden fixes.I would urge anyone who has this problem to take their car to their nearest Holden dealer. The dealer has a checklist and software changes that can be made and in our experience these fix the problem. Name withheld email A That's great news; the first clear indication that there is a fix for what is a most frustrating problem for those who have had to suffer it. Q In road tests and other reviews the fuel-consumption figures are generally given in two parts --- for the city and highway --- but the only figures generally given are for new and used cars being advertised. Is this one figure an average of city and highway driving, or just for city driving?Mike Damianos email A Manufacturers generally issue three fuel economy figures on their new cars, city, highway and combined. These are all derived from standard laboratory testing and relate to city or highway driving, in the case of the first two, while the combined figure is an average, so it would take in a mix of city and highway driving. These figures are made available to prospective buyers so they can compare one car with another to see which is the most economical in those different driving con- ditions. Q I have done over 70,000km since I fitted a dual-fuel LPG system to my 2003 Pajero diesel and have no problem with it, but I keep hearing reports of others burning valves and having other problems with cars fitted with these systems. None of them seem to have any first-hand experience, however, so I'm not sure if I should believe them. It has definitely resulted in a power increase and I now get an extra 200km per tank of diesel. I don't know if I should switch it off or not, what do you think? David email A You've done 70,000km without any problem, that's more enough for any potential problem to surface, so I would leave it. I have heard of some issues with engines blowing up on these systems, but from what I can gather its because drivers take full advantage of the power boost and driven their vehicles harder as a result, instead of easing off on the throttle and getting full advantage of the fuel-cost savings. Q Overall we are happy with our 2009 Mazda 6, except for a drumming noise similar to that when you leave a window down when all the others are up. From what we have discovered it appears to be a problem with this model, even though the dealer denies it. Would a change of tyres from the Bridgestone Potenza's currently fitted help or is it far more complex than that? John email A I haven't had any direct experience with this issue on the Mazda 6, but many people complained of the same noise on the Mazda 3. In that case there was little that could be done to fix it, a change of tyres might make a small difference, but it's only likely to be small at best and it's an expensive exercise. There is nothing wrong with the Bridgestones, they're good tyres. Q I am looking to buy a diesel automatic dual-cab utility to tow my Jayco 22-foot caravan, which weighs two-tonne when unladen and about 2.5-tonne when laden. My preference is a Nissan Navara ST-X, which has a towing capacity of three- tonne, but I am wondering if the 2.5- litre diesel motor is strong enough to do the job. What do you think? Greg Stephenson email A The 2.5-litre Navara diesel should handle your towing needs comfort- ably; the Navara is a great dual-cab ute for the family. It's comfortable, roomy, has a good towing capability, and is know for being economical. $11,990 DRIVE AWAY* NEW ER NA AN A $16 ,990 DRIVE AWAY* * FROM NEW AVVY AN A $13 ,990 DRIVE AWAY* THE NEW PROTON N E E AUSTRALIA * All offers available at participating Proton dealers and while stocks last on new Proton vehicles ordered and delivered before 31 December 2009.
