As with tools, skimping on price, when it comes to replacement parts, can be a false economy. With the number of substandard and counterfeit car parts growing, always buy components through reputable suppliers and insist that they are made to at least the same standard as those used by the car-maker. This does not mean that you have to buy everything from a main dealership, but a decent aftermarket supplier should know what you mean if you ask for ‘OE quality’. Unless they are coming from trusted traders’ shops, avoid tempting bargains on online marketplaces, for it is here that most parts of dubious origin are sold, according to many motor industry professionals. Using questionable parts and lubricants can increase your car’s fuel consumption and reduce its lifespan. Similar advice applies to other fluids, although you must heed any recommended specifications, especially in relation to engine/ transmission oils and antifreeze.
Only buy from a reputable supplier that sells Oe-quality parts. Substandard or counterfeit parts could cause untold damage.
