STP 66079US Oil Treatment (443 ml)

The engine is thoroughly smooth. I was very skeptical while thinking of which engine oil to order for my Father-in-law's 2011 model Wagon R as his car would be mostly be in village in interiors of Karad (Satara). The container was compact without any damage and indicating 3 Liters. The chief mechanic at Maruti Authorized Service station in Pune told me this oil is for Disel cars but I insisted him to put it in his car. Before I put this engine oil, I flushed the previous engine oil using STP Flush and then added STP Engine Oil Treatment to this oil to make total quantity of 2.9 Liter as the car completed 49000kms and coincidentally the clutch assembly was to be replaced along with Gear Oil and cable owing to wear and tear. The car post changing the engine oil was smooth like BMW without any noise I drove it for 200kms. The STP Flush and STP Engine oil treatment too does wonders as I have used them in my wagonr previously and makes engine smooth, perform better and increase the millage.

Have been using STP Products for the last 20-22 years now, based on advise provided by my father who happens to be an Aircraft Engineer.Have always been very happy using the company's products for petrol vehicle and now for a diesel vehicle as well. Not only protects the engine from heavy were and tear, but also provide a smooth ride and an easy engine start.Protects engine from over-heating, catching rust or even from freezing. Thus a product worth suggesting to one and all for its usage.Overall Satisfaction - '08' out of '10'.Rgds, Paddy...

Used in my 35000kms ran diesel Tiago just after oil change..I poured half of the bottle as the Tiago engine oil capacity is 4 liters and tass used petronas s5w-30 oil..they claimed 4 liters have poured on engine..so in terms of safety precautions I had poured 300 ml on engine..Oil is very thick ,more than like honeyAfter 75kms the oil began to show the miraclePreviously car sounds like Jeep on idiling and heavy sounds of engine after 70kms..now peppy smooth like that of new engine and even better..It not increased mileageBut it makes car to pull stronger and smooth and reducing the diesel sound now excellent peppiness in eco mode!!Use liquy Molly engine flush before oil change!!

The STP oil Treatment actually works.I always thought that these oil treatments never work, but boy was I wrong!I used this on an 5 year old car (55,000 KM) . The first 5 days didn't make that much of a difference. I could feel a slight improvement in smoothness, nothing else. But after doing 300-400KM The engine has been transformed!1) Engine feels so much smoother2) Engine Noise has come down a lot. (earlier I could feel the vibrations and engine noise inside the car) Now its silent.3) Engine revs more freely.4) Because the engine revs more freely we feel the pickup has also improved.This does work work but it can take some time for to work. 300-500KM.Couple of things Which I feel I need to clarify.a) Use this when you change your engine oil.b) also Change your Oil filter.c) If you engine oil capacity is 3.5L (Fill only 3.1L of Engine oil and then use the whole bottle 443ML) - Totaling up to 3.55LThe stuff inside the bottle is sticky.There has been no improvement in Fuel economy. This is still the same.Overall I am very happy with this product and will surely use it on my next oil change -> Which is after 10,000KM.

I cranked the engine this morning at around 20 degree C temperature and kept for half minute to see the vibrations before using this product.Turned off the engine and added around 150ml of this product to the crankcase.Cranked the engine again and kept on for 30sec time again, vibrations are felt less now and smooth when throttle input given.Product received in perfect condition with all labels and was imported in august 2019. So it was recent stock.Note: I did not drive the vehicle yet.I will edit this review right after pulling the vehicle in gears in the city and also after a long drive. Keep watching this space for updates.The long story.Oil Used: Idemitsu fully synthetic 0W-20 API SN (Not zepro eco medalist)This oil was manufactured in 8/2018 and was around 15months old when I poured into the engine during oil change. I also noticed some thick substance of some 15 20ml at the bottom of the bottle (that was the part of additive settled down due to ageing), without knowingly I discarded the bottle.The engine was making noise during acceleration and the noise vanished after reaching speeds of 60-80kmph in 5th gear.This noise was due to the missing additives in the oil and the oil is 1700kms run as of today.So I decided to add additive to the oil by purchasing this product.

I used this oil along with newly replaced engine oil of my Maruti Alto when I took up a long journey (around 1000KM). within 45 KM, the results were obvious. engine calmed down. NVH level reduced. felt smooth drive irrespective of ambient temperature (hot midday, - earlier using the same engine oil (authorized service center replaced), I had felt downgrade of power in the hot day and in a continuous drive; I had to give her rest for 20 - 30 minutes before to get same power). Now that is missing this time after adding STP oil treatment with the same brand engine oil(authorized service center replaced oil). In spite of continuous drive without rest (even I did not stop for tea or lunch, because I was in a hurry to reach home before it turns dark), I did not feel any power-drain, which I experienced earlier.It is worth the cost!

I have used this first time in my diesel cars .Once i crossed 300-500 kms . Can feel the the actual difference .Engine sound and mileage is same .Engine become smooth like butter , pickup has improved 20% .I will update the review again once i will cross 5000 kms

Used it 4 years. Great stuff.

STP hasn't changed in all these years. Great price for a proven product

Works as advertised! Reduced minor "tick" in motor.

Have an older vehicle that doesn't run very well and this seems to smooth out the engine a lot. So, I am very pleased with its performance.

The media could not be loaded.  Made for the high RPMs with ravecars so you know its a great product
