"My 1997 Vauxhall Astra had begun to give me very poor fuel economy. I saw G1 and thought I would try it as I cover many miles for my work.

The results were obvious and instant. The car has greatly improved in feel and economy. The engine is smoother and more responsive with less annoying engine rattles.

I went without the treatment for a weekend and the old bad performance returned. Thankfully I got some more and added it to the tank and everything is good again! "
