Now with HHC  high intensity engine carbon removal equipment! 

Increases engine efficiency,  performance, economy, and  proven to lower emission levels.

What is HHC carbon removal? 

This is a 30 to 45 minute process ( depending on engine size) to remove internal carbon deposits. These deposits reduce performance and cause internal component failure/malfunction. This process involves the introduction of  Hydrogen gas through the inlet system of your engine ,whilst running to break down internal carbon build up.

The effect of carbon cleaning on your engine is dependent on how dirty the engine is internally.

This build up is caused by

1) constant low rev driving 

2) short journeys

3) lots of stop-start journeys

4) long periods of idling

5) poor fuel quality 

This process is recommended to be used also as preventive maintenance every 9000km or 12 months, to prevent carbon building  up within your engine.

I had a great experience with Mark One Autos. I've been using them couple of years now and they are a great team. Recently needed work and my power steering is like a dream now. Thank you

Spent ages trying to research where to buy a used car. I was then introduced to Neil by a lovely gentleman who'd known him for years. The car is great & Neil is honest & genuine. 100% recommend this garage.

I'm so pleased with the service I received from Neil and his team. I broke down 100 miles away from home and Neil was so helpful in repairing my car quickly, and at a reasonable price, so I could get back home. I would definitely recommend this garage to anyone.
