Hydrogen carbon clean vs terraclean

[sam2k01]

Hi, was going to get my car booked in with this company in Hertfordshire...

It's a mobile service if you have multiple car bookings. Wanted to now if anyone has had a carbon clean with Hydrogen and if they noticed any improvements. Posts on his Facebook pages seems legit, but not sure if it's better to spend the extra £50 on my local terraclean specialist?

What's wrong with your car that makes you want to use this company?

Nothings wrong in particular, just looking to boost economy and I have read reports of slightly better performance? Has anyone tried a Hydrogen clean?

you are better off pouring a can of snake oil in the fuel tank.
i sell this oil on my website, its £15.99 a can plus 2.99 postage.

His economy or yours?

Fuel economy always drops in the colder months. You could try a premium fuel to see if that helps your MPG.

It's your money so you are obviously free to spend it where'er you so desire, but if there's nothing wrong with the car at the moment, squirting the delicate insides with a hydrogen doesn't seem ideal to me.
