    Rated 5 out of 5 by from Any engine I have used this product in many cars over the years, but I also use it in my 1989 Hayter harrier 41 lawn mower fitted with a briggs and Stratton petrol engine, I use it about 45 minutes a week in the lawn cutting season and have also used it in France in very hot weather for several hours a week, I am sure it is the Slick 50 that has kept this lawn mower going.

    Rated 1 out of 5 by from doesn't work for newer cars This is by far the worst product for any modern car as i've put some into my bmw f30 and it has straight triggered the eml on and after checking the errors has well and truly blocked my car's dpf,not to mention other electrical faults because of this stuff.I recommend using this if your intending on causing your car major engine damage as this stuff is a load of garbage

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.
