Put fuel to the test
Is there any real benefit running my new Toyota Kluger on premium fuel (95 or 98) instead of 91? Claims at the petrol stations include cleaner engine, longer life etc.

Generally you can get better performance and economy from running the higher octane premium fuels but they cost more, so you have to weigh up the benefits against the cost. I suggest you run a test: use a tank of regular 91 fuel then a tank of premium and see for yourself. AUTO OIL CHANGE Nowhere in the service book can I find any reference to the automatic transmission having to be serviced in my 2008 Toyota Kluger KX-S AWD. It is now just over three years old and has travelled 35,000km. Should the transmission be serviced?

Generally manufacturers today do not recommend servicing automatics. The transmissions are ‘‘ filled for life’’ in the factory and according to the makers don’t need any servicing. Auto transmission experts would disagree and say that you should change the oil every 25,000km or so, and carry out a major service every 100,000km or so. On that basis you could have the oil changed as a precaution but if you’re not towing you could safely let it go for a while. ALEAK BEFORE TIME I was concerned recently when my dealer said my 2006 Holden Astra convertible had developed an oil leak and would be very expensive to fix. I got another opinion and was told there was a lot of oil around the head gasket that would need investigating. My concern is the car has only done 78,000km and has been very well looked after, never thrashed or driven roughly. Any comeback with Holden?
First you must find the cause of the leak. Depending on what that proves to be, you might be in a position to approach Holden for help. Until you do that, there’s nothing Holden can do for you. SNAKE OIL ANYONE? In later life, I amnot using my Vwpassat as much as I’ve used other cars. Rarely now do I drive more than 50km. A socalled European specialist motor mechanic told me that short runs are bad for the car, even possibly requiring a new or reconditioned motor in some
