Happy with the result.
This made the goopy stuff come out of my engine after being sat still for extended period. I was warned that using this type of product doesn't come without risk. The goopy stuff may be what's holding the engine together. In the end, I had no problems after using but have heard stories about leaks caused afterwards.

Is very effective, maybe a little too effective it wore away at seals causing oil leaks. I would not recommend using this on a car any older than 4 years.

did wonders for my diesel!
I tried it with an oil change @130k km - I can feel a notable improvement in the fuel consumption of the vehicle (~3-4%). I also changed the air-filter, so not entirely sure what contributed to what, but would still recommend this product!

Recommend !
This is a one of the few Products which I recommend and suggest to everyone out there! I use this product on once in 3 oil changes. Been using this product on my car from 20,000KM! Today the car has done close to 70,000 KM and still feels new and sounds Great thanks to STP oil flush and engine oil additive. What this does is help remove all the carbon and sludge from the engine and keep the internals of the engine fresh and clean. Unlike the other Products like Xdo, Liqui - STP Engine flush works and I have seen it make a huge difference over time. Dont expect miracles using this product, Dont expect Better mileage or better performance using this. All this does is help your engine stay fresh, clean and healthy. Warning - Do not use this on OLD engine (Done over 1-1.5 Lakh KM) which has never seen an oil Flush! as sometimes this can Damage the oils seals and cause engine wear. Way to use this product - > 1) Start your car, let it warm up. 3-4 minutes 2) Use full bottle - Pour it into the engine 3) Let the car idle for 10-12 Minutes (dont drive the car or raise the engine just let it idle ) 4) Turn of the car 5) Drain the oil 6) Change the oil filter. And Finally 7)Pour in fresh new oil and use a new filter And you are done!
