    Rated 5 out of 5 by STP Diesel STP Diesel treatment is a good product, it does what it says it does. 23 November 2015
    Rated 5 out of 5 by Amazing product, it should be part of the 'Ronseal' range The oil treatment does exactly what it says on the tin. With the cold mornings my Mondeo estate was getting a little rattly until the engine was warm. I put this into the engine about 2,000 miles after a service and what a difference it made. The car from cold sounds much quieter, not so metallic. I have noticed that even when warm the engine sounds smoother and sitting at lights it doesnt rumble as much as it used to. All round a great product. I recommend STP for any of their items / product range. They are a company with a long history of producing high quality additives for oil and fuel. My one gripe, my other car a megane mk2. I used this straight after a service, and my issue is that the oil filler cap is also the dip stick and is quite a small hole. As this additive is very thick it takes a while to pour in. It must have taken me about 20 mins. This is more of an issue with the car though than the product! 18 February 2015
    Rated 4 out of 5 by easy to use i bought this product on the recommendation of my jaguar mechanic and have noticed a difference in the engine sounds (and it wasn`t noisy before!) 10 July 2013
    Rated 5 out of 5 by Instant protection I was using a more expensive oil treatment before & was recommended this by a friend. Instantly noticed the engine run quieter & still is after 8500 miles. Great product & fantastic value for money 02 March 2013
    Rated 3 out of 5 by Didn't Really Work for Me I added this to a recently bought high milage (100,000+) diesel car and bought this product to try and help support the engine. To be fair I hadn't driven it much before I used the STP Diesel Oil Treatment but noticed no difference at all. I'm guessing it's useful to add between oil changes but it's not going to make a silk purse out of a sows ear! 28 April 2012
