how worried should I be

[caz]

Just been having a bit of a thing with a turbo astra on my private runway. And I noticed on changing gear from 4 to 5 I got a puff of smoke. I'm taking high rev changes in to fifth, as I let off to change ....smoke. Not white o blue but grey and just as I let off. :?

Put my mind at rest

Soundl like petrol-nothing to worry about.

If it was only a little puff, I wouldn't worry too much........just yet.
It might be the first signs of a problem or it might be nothing :?
Have you filled up your oil recently?

Just keep an eye on it. (But don;t forget to look where you're going too )

Have you filled up your oil recently?

Yeah, just done an oil change. Me oil pressure isn't as high as when I first got the car, now sits around 4-5 now. But since me last oil change a week ago, me oil temp doesn't go mad hot straight away like it used to.

It might be a slight over fill, in which case it might be a sign that your rings are starting to wear. It might be worth checking your breather system isn't blocked.
If it was only a one off, I wouldn't realy worry.
