    Rated 5 out of 5 by from Slick 50 Engine Treatment I've always used Slick 50 Engine Treatment, it's gone up in price over the years but it cant be co-incidence that i always get over 150.000 miles out of my car engines, and they're still going strong when i part exchange for a newer model.

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
