Portugal 2007 Defender 110 Puma 2.4 HT Keswick Green

I am quite sceptic about putting Censored into my engine too. I went to buy a fuse in a moto-shop and then had this impuls to get a bottle of Ceratec and give it a try.
I was surprised by the effect in a big way. I was not expecting to see any significant improvement and then I looked at the fuel level and trip distance. So, I put fuel to make counts. That was the first fuelling when I got 9.2l/100 km. After I made almost 400 km on a highway and I put fuel again to see those 10l/100km (a bit more than 10, because I put the tank really full).
I have been having, as you can read in my first post of this thread, bad fuel economy for 2 years and now this surprise. I am still not sure what to think about it... Bergos

I'd replace the injector seals and redo the pilot injection learn.

Also - have you still got the EGR valve in place? The home of the first modified Keswick Green 90 - and the first 2.4 Puma through both the 200bhp and 550Nm barriers.

So, new update on my fuel economy.
The car had been parked for 2.5 months with full tank.
After driving on mixed roads for around 900 km I put the tank full again and the fuel consumption went up again to 11.65l/100km (8.58km/l, 24.24 iMpG).
I am confused and don't know what to think about the situation. Was the Ceratec just a coincidence or it had an effect indeed but short lasting...
Or maybe the diesel in my fuel tank is not so good after 2 months...
After I did 400+ km on a highway and didn't fill up but I am sure that the results would be even worse.

So, what can cause the fuel economy to go up and down from 9 to 13 l/100 km?

Any hints? Bergos
