65934US Diesel Oil Treatment (300 ml)

Used it in Renault Duster 110 AWD model. Within 5 mins of idling, the engine sound reduced. After running 2 km, the engine felt light and eased up. The rattling, while you rev up above 2K RPM, reduced and felt slight increase in power too. I'm pleasantly surprised and wonder what magic this stuff has done to my 2 year old car. Though I'm happy with the product during the short usage period, I'm skeptic about the effect on my engine during the long run. I shall wait and see. I do not personally promote or recommend any product, so the decision to use this solely lies on the owner of the vehicle.

Timely delivery & product as described. Thanks Amazon India. Used it in my Renault Pulse 1500 cc diesel engine at 40,000 kms. Paid service. At the beginning I used STP diesel engine oil flush. The 10,000 km. run old diesel engine oil was drained. Following this, a new diesel fuel filter was installed by the garage. Four liters of new fresh Shell engine oil was poured-in. To this was added the STP diesel engine oil additive. The engine has become unusually quite. All diesel-ness of the engine like vibration & clatter have dramatically reduced. It's subdued now. Smoothness is the word which best describes the engine performance. Pickup has increased. As the car is mostly used in the congested city, an average of 17.8 KMPL is not bad, with AC on. (A suggestion to the vendor: Please do not apply your sticker on the directions for using this top class product.)

Used in my Ford Figo but didnt see any major improvement in performance. There was bit reduction in noise but not making much of difference. Wont buy next time. Update: seen improvement in car performance after 500 KM of run. Engine is smoother, pickup is good specially at lower speed and higher gear.

STP is really effective products Friends really you trust me is great amazing products. I am using this product in my Xylo E-8 Friends believe me I am 1st time using this product & I just show video's in YouTube so I am oder this product but really after using this product my vehicle voice is totally change & so smoothly running mostly people is thinking after oil change also engine sounds is changing but really if you use STP products so is different results. My vehicle is 5 years old & 18500/Km I am running but after service my XYLO E-8 so really is different to everyone services results. It's totally amazing best product & I really required to everyone if you love you vehicles so you use this STP.

Used it in my New Brezza. Although I didnt get any Milage difference there is a noticable mute with Engine Noise. May be with regular usage willsee the difference.
