Checked your oil lately?

[TASH1]

Yep checked mine yesterday, 12500miles and needed 1/4 litre of 504.00 spec Castrol edge.

Only had car 5 weeks, bought with 11K on clock at year old and noticed at first that exhuast tips where black at base after each drive, they are now cleaning up as I do long trips of 80 miles/day. Lad at work followed me last week and said there was a puff of blackish smoke for a moment when initially accelerating...anyone else noticed this. Could just be to do with lots of short journey's by last owner.

Car goes in for leather cover to be changed on the 31/07 and have asked garage to  through computer service, they said they would only service if needed! believe it or not, I wanted it done to be safe.

P.S. car runs fine and has just had the engine managment up date.

yes, mine always does spirt out some black smoke on hard accelaration, only for a split second, tends to be more if youve driven for lots of miles at slow speeds, just normal, nowt to worry about. It makes peeps think your driving a diesel ,and they think ,  that poor guy has only a slow diesel car, but oh sh!t, by god it's gone!!!!!!

Wonder what causes it??

[Phil mcavity]

 lots of factors ,well normally black smoke in a petrol car is unburnt fuel,maybe the time is takes the ecu to understand where youve put your right foot,the load thats put on the car depending on whether your going uphill at the time,or maybe because often what you do subconcously do is "lift off" the accelator, which would again overfuel it for a split second. thus giving some black smoke.

I am led to believe that the detergent properties of modern unleaded fuels also contribute to the black tail pipes whilst they are shifting crud from inside your engine! I am sure someone will correct me if this is wrong

Thing is... some diesleds go like stink!!  My old Fabia vRS used to seriously shift... best gears weer 3rd, 4th and 5th... pulled superbly... mind you, even in sixth gear doing 80... car would stillpull amazingly if you put your foot down!
