    The engine rebuild gives a newish sort of car. £650 to buy the car. What was cost of the engine rebuild?

    I used to average around 210 miles per 1/2 tank driving to work in my 2004 RX8, driving on motorway, country and rush hour traffic filled roads. the trick for me was to pre mix the fuel and to shift at 2800 rpm in heavy traffic. i use the full 10k on slip roads and when ive been stuck in traffic to clear the carbon that builds up at low revs

    10:35 I see what they were trying to do,They were trying to keep you awake by counting but they failed to remember the counting sheep theory that counting can actually make you fall asleep for sheer boredomYour better off thinking of ball bearing turbos and fun stuff then counting.

    Those cars use fuel to lubricate the engine, so im guessing hes caused some damage

    • josh langley
      josh langley Month ago

      HQ, it’s oil added to the fuel that does most of the lubrication.. It’s like a two-stroke engine.. I’d be interested to know why you think some damage was caused because apart from general wear I don’t think so..

    GoTwo suggestions:
    1. Try it again, after the rebuild... zgonna be different.
    2. Try it again... at twice the speed.
    Quoting my first mate to actually own an RX8: "whether your drive at 80 (km/h) or 180, it drinks the same. So I might as well drive it like I stole it all the time."

    I have the fix for your bashed in fender, take a phone book meter the thickness, place it inside the fender with the door open, close the door so it leverages the book to push the edge of the fender out and Bob's your uncle.

    K, I drove 1,000 miles down hill, with the wind at my back, and, I ONLY got 20.96 MPG. No speeding (OK, maybe a lil speeding) but, generally- 6th gear the whole way. You ROUSTED my very best, although I didn't tape the hood gaps, and, I certainly didn't hyper mile either... Good on ya!

    hypermiling in Winter and on wet road, woun't get you far. colder air is much denser than hot air. The molecules in hot air are farther apart. so you wil get farther in the summer time
