Wynn's Super Charge Oil Treatment - Enhances Viscosity - Restores Compression & Pressure - Reduces Oil Consumption & Smoke Emissions - Prevents Metal Contact & Engine Wear - 425ml

I've used this stuff for years now over three different older cars and it's been fairly transformative, which I do feel a little ridiculous saying but it's actually true. The engine just seems to run so much better (quieter, smoother, no start problems) after I've added this so I swear by it these days to anyone who'll listen. Besides, it's really cheap so give it a go - what have you got to lose?

Great stuff really works for fuel economy and makes engine quiet. Would advise full oil service before use to see benefits from any oil fortifier. But as seen on another review people under impression for blue smoke. No that means piston rings fried. Engine rebuild in my opinion if blue smoke after been investigated and white smoke indicates water or moisture in oil. A little on start up is ok condensation as if sitting for a while the car water can sit in exhaust system once warm should be very little as catalytic converters turn bad gasses into H20. So sometimes you might be in traffic and see car infront with a little water from exhaust its normal but if it's running out big problems. Hope that helps. Also when you put your car into a garage for full service don't think they do everything as seen bosses tell them if not to bad of just skip that or this like plugs, oil , air filter cabin filter or pollen filter. Brake fluid, and more. Full service should be every fluid checked and changed also brakes checked just lots of checks. But that's how they make money and charge a fortune. I am lucky I found a great garage and not often you do. Hope this helps someone.

My 11-year-old diesel Nissan Qasqai started showing its age with rough idling and a worrying check engine light. After some research, I decided to try Wynn's Super Charge Oil Treatment. I was skeptical, but the results were remarkable. Within a few days of adding the treatment, the engine light disappeared and the rough idling smoothed out. The light has been on for 5 years and any number of garages could not solve it! My car felt like it had a new lease on life. It was more responsive and quieter Wynn's Super Charge Oil Treatment is easy to use. Simply add it to your engine oil during an oil change or between changes. It's a small investment that can save you a lot of money in the long run by extending the life of your engine. Highly recommended for anyone with an older vehicle or anyone who wants to keep their engine running at its best.
