STP Synthetic Oil Treatment for Petrol and Diesel Engines 300ml, Protects Against Engine Wear, Reduces Pistol Deposit and Oil Consumption, Mechanical Car Cleaning Products, Made in the UK

Timely delivery value for money This is a great product and much value for the money. It arrived on time and I am very satisficed with this product, the price was reasonable, the item was suitable for me and I recommend it for others who are looking for the same item. I will probably order it again and wish you all the best.

Have been using this product for over 20 years. Never had engine mechanical problems and noise levels reduced

I've used this twice now. Many years ago with 1970/80s cars I always used oil addatives, more meanigfull back then. However at the current price point I thought I would give this a try. I've used on an old Mini and VW Up on both occasions it has seemed to make the engine run smoother and quieter, especially the Up. Its my sons car and he has noticed the difference also. So for the price I would 100% recommend at the next service. Can't go wrong really.

Great product used this in the 80s, helps to keep the oil at its best between services

Giving 4 stars for price & delivery only, hopefully the product is of good quality to do its job, but can’t know unless I take the part off the vehicle!. Confident STP make a good product.

Great but they don't do it anymore at a decent price,

Good deal!!

good to have dor high mileage cars. For me I only felt the difference only for the fist 3or4 days of using it. the only thing that I noticed was that the engine noise became much less in the first 3 to 4 days. but after that I felt it came back to normal. it did not change anything related to fuel consumtion or engine performance. but I would say the same for most additives available in the market with value less than £15. but for 3 pounds, it worse to try. this is why I gave it 3 stars.

Da anni uso questo prodotto ( ho avuto sia auto a benzina che diesel ) che mi dà la certezza che il motore duri più a lungo azzerando il consumo di olio ! La sua funzione è quella di lasciare un filo di olio sulle pareti del cilindro non facendo strofinare il pistone a secco dento l'alloggiamento ! Inoltre rende l'olio più denso permettendo di resistere ai consumi dovuti al logorio delle fasce elastiche ed altri componenti . L'olio reagisce meglio agli alti regimi e si sente il motore più compatto e pronto alle accelerazioni ! Il prezzo non esagerato rende il cambio olio meno gravoso . Spero di avervi aiutato nella scelta .............

Aggiunto ad olio synt 5W30 ha dato qualche miglioramento su fluidità e consumo carburante. Nessuna attenuazione apprezzabile, invece, sulla rumorosità del motore. In conclusione: è utile, ma non aspettatevi miracoli.

Da anni ho usato gli additivi STP per ridurre il consumo d'olio su diversi motori a benzina e secondo me sono efficaci, non eliminano il consumo d'olio ma lo dimezzano. Il proddotto è arrivato in 2 gg ed è esattamente quello previsto, inoltre il prezzo è ottimo

Risolti tutti o problemi di viscosità e ticchettii vari. Lo consiglio
