    Rated 5 out of 5 by SortSTP oil additive Sorted out our smoking engine quickly, cheaply and with no hassle 10 May 2013
    Rated 5 out of 5 by Buy this and you won't regret it! I added this to my 1997 Ford Fiesta 1.25's oil a year ago after an oil change when it had 68,000 miles on the clock, and prior to the change it idled quite harsh, and didn't sound too good. But after adding STP, the idle smoothed out to a rock solid 900RPM, and there was no nasty noises! The car now has 75,000 miles, and is still on the same oil, but the additive is still keeping the engine running as smooth as it did when it was first added! It goes without saying that I will be buying this product again for my next oil change soon. 08 April 2011
    Rated 4 out of 5 by Very good product for quick treatment Very good value for money, simple to use, does exactly what it says on the bottle!!!! Cannot tell if it has worked completely but it has definitely helped a lot. No more oil patches on the road outside my house!! 02 November 2010

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.
