    Rated 5 out of 5 by from 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!

    Rated 5 out of 5 by from 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

    Rated 3 out of 5 by from 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!
