    Rated 5 out of 5 by from Hope it does what it did with my previous car My previous car was a Volvo V70 1997 diesel it did 187000 miles and is still going well I believe this is due to slick 50 and good oil . I have now got a 2017 VW golf gtd I hope that slick 50 does the job again Regards Harry

    Rated 4 out of 5 by from Great Service.....bravo First of all very sorry...to write late.review .I booked an engine treatment online and was available in halfords Ruislip branch. when i arrived there to collect my item. The halffords manager was serving me. and he realized that this item they dont keep in stock but still shows on online. To serve the customer (myself) and keep him happy with their best services , he explained me the whole scenario what happened about this product (Wynn's Formula Gold Engine Treatment 500ml worth £5 in SALE) which is actually they don't keep in stock, and offered me other product SLICK 50 HIGH PERFORMANCE 750ML worth £ 24.99. Just to make sure that as a customer i will not get dissatisfaction from halfords....I really appreciate the branch manager(sorry dont remember his name,) he provided really a very good customer care... And product worked very well too. Once again thank you very much to Ruislip Branch Manager

    Rated 4 out of 5 by from works as described on package Used slick 50 for many years in a variety of privately owned cars - they have lasted into the 100 k plus mileage and always felt like power and economy was stable throughout. Gives a peace of mind feeling.

    Rated 5 out of 5 by from Slick 50 I've used slick 50 for years. As a classic mercedes collector my lowest milage car is 170,000, highest 450,000. I use slick 50 every other oil change and am looking forward to the next 400,000. Long live slick 50. Very highly recommended.

    Rated 5 out of 5 by from Great product, a yearly must have! Great product, seen a difference in engine noise and the car is a lot quicker off the line. The car feels a lot smoother.

    Rated 5 out of 5 by from Slick 50 High Performance Engine Additive This product is the best stuff in the world for keeping your engine slippery over tens of thousands of miles. My Celica 2.0GTi gets an extra 5 mpg at 60 mph, but keeps that same mpg at 85 mph. Also the High performance stuff gives that extra zip on the accelerator, I cannot go back to standard oil now as I lose that touch of zippieness I get from this product. My power at the wheels has also increased with lack of drag on the engine, so I also use the gearbox slick 50 to reduce the 50bhp drag in this area. My engine has 130k miles and I've done them all with no problems, it runs a dream. Does not get any better, what a product.

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.
