    I would very much love to fix the car myself like you do but I lack necessary knowledge and practical expertise. Looking into "Diploma in Transport Maintenance IMI VRQ L1" part-time. I am 50+, Happy to learn something other than IT but most of the courses are aimed for 16-19 age group. Not sure if it is suitable for me :-) or where to find one.

    As I said on the other place, just tell me the make and model of his bike, and the colour of cycling club top.

    ...think of it as a favour to humanity.

    I just followed your advice today atW. If the MPG doesn't increase sufficiently I shall be suing you!

    how much does the additive cost, compared to just getting your fuel from somewhere like BP, regular diesel? As I find BP diesel runs well on my car with their additives.

    Recently, I used a DPF cleaner which lowers the temperature at which regeneration happens. It appears that regeneration normally takes place at around 600 degree C which doesn't happen if car is used mostly for city driving.

    1. No more dashboard symbols, warnings and alarms.
    2. Engine is extremely smooth that I can't even hear the engine running (haven't gone deaf yet! :-))
    3. Performance is amazing. Did about a 400 mile journey and it was enjoyable. Felt like driving a new car.
    4. I am no longer worried that the car might stop in the mid-way that I had to make an emergency brake on the hard shoulder.

    I am satisfied and can confirm that fuel additives are not a myth or a snake oil!
