    Bedding in info

    Hey folks i've done a lot of searching through various threads and websites but looking for your opinions!!

    I've had the pistion rings various other seals and guides valves to cure an underlying missfire and vast oil consumtion. seems a LOT smoother now and no smoke from exhaust (touch wood) was just wondering what the correct or best procedure to getting it running for longetivity etc

    So far i've done 95 miles on petrol only(have lpg too) as i was told to do this by the mechanic. not been above 3000 revs as yet and i'm going to change the oil about the 150 mark. do i increase the revs per say1000rpm/ 50 miles or so. also read not to drive in 5th gear full throttle.

    Any info would be great lads. zafira z18xe

    the rule of thumb is to drive at varying revs below 4k, not to labour the engine and change the oil after two weeks of running in.

    how long below do i stay below 4k and when do i increase revs? surely the oil change would be judged on miles instead of time would it not?

    you increase the revs during normal driving, you only need stay below 4k for a few days of varying revs driving. i said two weeks based on an average of a 100 or so miles per week. it is not hyper-critical, but change it within a couple hundred miles.

    If I recall, when I got my car new, the handbook suggested something to the effect of what you've been doing already. I will try to check (though my handbook is in the car and the car is in the garage!) though I think it was keep it under 4000rpm for 1000 miles or something like that.

    There is a train of thought about revving the 'rear' off it from new, however given I did it by the book exactly, and at 155,000 miles was only losing 1 litre of oil every 20,000 miles, I subscribe to the rules in the handbook!

    ok mate i get what you mean. will get the oil changed about the 200 mark then to make sure the oil filter catches most if not all the metal bits.

    ok mate no problems no rush. i think i'll go along with that then. i rarely go over 4k anyways so will do that for the 1000 miles as said. yeah i've read varying thoughts as to drive it like a granny or drive it like a boy racer but think i'll take the granny route to be on the safe side.

    nry i realise your an lpg driver too, the mechanic said not to drive on lpg for time being till there properly bedded in. why is this out of curiosity? and would this not affect the injectors if their just sitting idle all the time? should i run the rank empty? sorry for all the questions lol

    cheers for the replys guys.

    No idea, I drove mine on LPG pretty much from new....I suspect that the slightly better lubrication of the combustion chambers and head/valves from the petrol is why they have said this but never heard it before. LPG injectors empty when on petrol/petrol empty when on LPG so either way one of them is empty

    Can I ask how much you paid to have the work done?

    Just that I'm in a similar position so am looking at options.
    ... indicators do not give you right of way!!!
