If true this would be some improvement !!

Hmmmm interesting. I think I will be chicken and let others test it first and see if they get any ill effects. Could be good though if it works.

I'm going to give it a go on one tank and see how I get on.

 

Fingers crossed!! :)

I asked a combustion engineer about all this stuff. He said that the Ecotek also claimed to do this - resonate the fuel so that it vapourised more easily (better spread in the pot).

 

He said to me, dont buy it.

 

He advised that it was better to buy a tank of optimax and take the car for a drive at 70 in 4th gear for half an hour. It will give the engine a high rev clean out, and help the fuel to flow as it should do (ie. when it was new with clean injectors and clean pots)

 

I did this, knowing that a head gasket change was on the cards soon (160,000 miles). I got the head overhauled during the gasket change and the garage commented on how clean the head was. I get full power no problem - even after 13 years.

 

I ran redex through my fiesta (15 years) and it was amazing. Do it properly - down the spark plug holes on a warm engine. When you start the car, you will see a huge plume of thick black smoke from the exhaust - thats your efficiency returning.

 

My Fiesta (1.1) would go from London to Coventry (123 miles) on 10L of fuel.

My Mondeo will do it on about 13L.

I wonder if adding a bottle of Wilko paint stripper would improve my mpg?

Not heard from Hijacker in a while - do you think he's stuck in deepest darkest Brighton with a melted engine? :lol:

 

adding a litre or two of acetone to the fuel tank of a car, if it doesn't dissolve the pipes or the carburettor float first, causes the cylinder temperatures to rise to the point where pistons or cylinder vales melt and fuse

My plans to make it Kazakhstan on one tank with this additive have failed SeatKid. As Borat might say, "Is not good".

 

Tried it and overall economy was ~4MPG lower. Now back to Shell Diesel and all is well.

 

As a diesel owner will have to find other ways to penny pinch!

i use the bio diesel ad to the tank at 5%, runs cleaner and get 3 to 5 mpg better.

As any bodyelse tried this ?

And if so, is it worth paying the extra for Optimax ?

Do you get more miles to the gallon ?

I've tried optimax, no more mpg just a slight improvement in torque and response!

Waste of money.
