Must admit that I was quite tickled by Jack's comment.
ANYWAY, I conveyed the message of a polite decline this morning, and I was offered a great deal I just couldn't resist.
In my daily drive, the W126, I have now TWO (2) of the devices installed, and I need not have to pay until I am completely satisfied with the results. I also have their guarantee that nothing will happen to my engine.
So, I am going to start a journal at 118795 miles clocked in when fitted with FuelMax. Subsequent to that, I have also pumped a full tank and recorded all the details.
Since I am embarking on an independant study of this, I thought it better to make known here the pattern of fuel consumption.
Starting from this year's record:
3.1.2003
Odo. Reading 114441 miles
134 miles @ 24.318 litres

There would be a marginal error imputed in the computation of the average mileage depending on whether it is filled to the brim. For simplicity, I shall try to be as consistent from now on.
So - until the next fuel pump.
