The Road Ahead : August 1st 2012
KNOW YOUR CAR MOTORING LAST TIME WE talked about some of the home-spun methods for diesel fuel system maintenance found on the internet. These included rather alarming methods, such as adding some petrol into the tank to help clean injectors, through to DIY servicing of system components. Adding petrol is a bad idea. It lowers the fuel's flash point, which may result in a safety hazard. Importantly, it also changes the fuel's combustion characteristics with the potential for engine damage. The finely machined, close fitting fuel system components rely on the 'oiliness' of the diesel fuel for lubrication. Petrol strips the lubricity away and expensive damage can result, especially in late model common-rail systems. Attempting DIY servicing of injectors, pumps, etc is another bad idea. It's like attempting open-heart surgery no diesel diy WITH JOHN EWING, RACQ TECHNICAL AND SAFETY POLICY With your go via account, you're set to travel on all toll roads, bridges and tunnels in Australia, now and in the future without having to do anything extra. And if you're visiting Brisbane, you can go through all local toll roads, bridges and tunnels with a go viaroad pass. Isn't that good to know! go via any toll road govia.com.au VIA546_0712 on the kitchen table. Contact with high pressure fuel can pose a serious safety hazard, causing human tissue damage or even death. Specialised knowledge and very sophisticated equipment and test benches are required to reset critical parameters such as opening pressures. Cleanliness is vital too - even lint and airborne dust can cause major problems. Diesel specialists have special airconditioned 'clean rooms' for such work. In fact, most general mechanical repairers leave such repairs to diesel specialists. Home mechanics would be very wise to follow suit. car questions Q. Should I trade my car in or sell it privately when I buy a new one? A. There's no one right answer. Trading can be convenient and easy, but the price you get will usually be lower. The higher price for a private sale is offset by the inconvenience of advertising, dealing with potential buyers' enquiries and viewings, getting a safety certificate (if selling registered) and timing the sale and proceeds thereof with new car delivery. Either way, research what your car is worth. Q. Where can I find what oils and lubricants are right for my car? A. The owner's manual or relevant workshop manual should provide details. And most of the major lubricant makers' websites have searchable lube guides with specific vehicle listings.
