    Quick update:

    I syphoned some petrol from my wife's polo. Did a quick drive around the neighbourhood and noticed a lot of white smoke. From my experience, that is probably the sludge in the engine working its way out. I'll go out for an extended drive this afternoon to give it the beans and see if performance increased as well.

    I think you used the wrong formula... here is the calculation...

    I think the consumption is also factored into the calculation above (post #22)... towards the top right corner...

    100% correct. Once the sludge has been burnt off you will need to check for a nice blue flame out the zorst as the petrol eats into the sulphur deposits around the exhaust valves. Sulphur burns with a blue flame in oxygen depleted air. Diesel tune up 101.

    Very dangerous advice, less contact with road means brakes would be ineffective thus causing an accident similar to braking on ice..

    It also helps with clearance. I got 2" more under the diff. Serious. The tyres are also lighter and helps with changing a flat. Remeber to fill the spare also. You can load more with less sag in the back.

    Just came back from the trip. I gave it all it got, there is still a lot of smoke - amazing how much sludge was in the engine.

    The only issue I have is that the engine has too much power now for my liking. Thinking of selling me Navara.

    Anyone interested? It runs well, I promise.

    Full service history.

    I know that a lot of chaps are taking this as a joke but pure N with atomic number 7 is used by all racing teams more stable at temperature so they can monitor easier , as the air quality differs from regions making if harder for them , for us common mortals air is free and that is what your car is designed for , all the light gasses (H ,HE etc) will just leak out (the molecules are small and the tyre design does not allow for that) and they cost a fortune
    But if the tyre could handle a light gas should be interesting , I think it will lower the car ?

    Back in the day whenever someone got a new car it'd be a huge thing one particularly braggy guy down the road deserved our teenage wrath, we'd sneak into his yard and add petrol every week to his red 123 series 200 mercedes (the flap was on central locking and those days cars weren't really locked) this went on for a number of weeks and he'd brag to everyone how fantastic this new German car was on fuel.......
    Then we started to syphon out some fuel every week and he was absolutely shattered about how his consumption dropped and dropped , never did tell him

    yes most are taking the piss out of this becouse air is made up of 78% nitrogen 21%O2 and and rest small amounts of other gasses, to do it right you use 100% nitrogen

    You must do like with white side wall tires. When you park your car on the street next to your house the tires on the street side must have white walls and green valve caps.

    On 4x4 you need special compressor for the street side tires to refill those with nitrogen. In soft sand you have to disconnect the drive shafts to the tires filled with air to prevent them over heating.

    Try inflating your tyres with at least 78% nitrogen.

    It works.

    I deflate and inflate my tyres too much for me to use the nitrogen pump at a tyre fitment center

    Scheduled maintenance on thermal imaging coolers requires helium to be recharged.
