This product has had some bad press because of the way it is being distributed. The product does work and doesn't deserve the criticisms of the uninformed sceptical few. I run a fleet of 30 Mercedes Trucks and have an annual fuel bill in excess of £500,000. We have used the MPG caps for the l ...

As technology advances and the newer cars become more fuel efficient in their own right, these capsules do not have such a marked effect in the area of huge savings.
In older cars they have constantly shown tremendous results in saving money for each tank of fuel run through the engine. We have been ...

I have been using the MPG caps for about tow months and have seen results, saving about $4 every time I fill my tank, my family uses it and seems the same results as well as many friends that save money using the MPG cap.

It is not snake oil. After like 3 tanks you will see a significant increase in mpg. I used it for a while and increased my miles per tank from about 450 to 550 (TDI). I got lazy and stopped using it and after 4 or 5 tanks, I went back to 450ish miles per tank.

Sorry people but after 5 months of testing the MPG Caps in my 2004 Toyota Camry, 1973 VW Bug, 2005 Ford, 2005 Toyota Tundra, 1990 Ford Pick -up and lots of other various autos, the results are not good. I actually got lower miles per gallon. I have had over 70 people try the caps and only 15% showed ...

After two tanks of fuel using two caps per tank I gained an increase of almost 11% in my Citroen XM. I have now used a further three tanks of diesel with one capsule per tank and the 11% has remained constant. I'm saving around £6 per tank after paying £1.25 for the MPG-Cap. :-)

I wasn't sure MPG CAPS was working and was going to give up on it before I started noticing the effects, but that was about 6 weeks in. MPG CAPS are excellent, saved at least £10 a week!

I drive a 2.5 Diesel Range Rover, heavy on the fuel!! These MPG CAPS bad boys have saved me hundreds of pounds. Nothing but good things to say about them.
