Internal Engine Detox

CHG’s exclusive technology restores MPG, reduces CO2 emissions & helps you pass your MOT.

According to the DVSA ‘Over 13 million vehicles have taken the test since it was changed on 20 May 2018. Of these, 1,926,557 petrol  (34.6%) and 1,573,492 diesel (33.3%) cars failed their MOT.’

Our unique technology provides our customers with cost saving benefits. These benefits help promote a more efficient and cleaner operating engine. Central House Garage’s exclusive technology uses portable hydrogen technology, which allows for use both in and out of the garage, working off the vehicle’s battery.

Our technology restores your vehicles original power and mpg. The treatment can also prevent excessive wear of engine and exhaust system parts, potentially saving you thousands in costly repairs. Our customers notice a smoother and quieter idle, with improved acceleration and greater overall performance after the treatment.

Harmful emissions are dramatically reduced. In recent years MOT tests have continued to become stricter on CO2 emissions, our service dramatically lower these emissions and helps pass MOT tests.
