Should my mechanic only use genuine parts on my car?

For most owners of modern cars, typically it’s their mechanic who sources and fits the parts for their car.

The choice will vary with the type of parts needed, and the age and model of the car, but when your mechanic calls to explain what you need, it pays to have some knowledge of your options to make an informed choice.

Genuine parts are made either by the vehicle manufacturer or by suppliers making parts to their exact specifications. These are called original equipment parts or OE.

Non-genuine parts are made by other parts manufacturers and are close to the original part but not the exact specifications.

There is a perception that genuine or OE parts are the best choice, but this isn’t always the case. Aftermarket parts may be of the same or better quality and also cheaper.

There are, however, some parts designed to look like OE parts which are counterfeit and of questionable quality. These are often marketed online directly to consumers and are potentially dangerous when in use.

Reconditioned parts can be a good choice if there is no new part available, and they usually come with a warranty.

Used parts can also get you out of trouble where there is no other option, but their warranties will not be comprehensive, if they have any at all. Still, a used OE part could do the job just fine and reputable vehicle workshop will be able to make a judgment about this.
