Try and keep it at about 1500rpm when pulling away. It will judder if there is not enough throttle. As long as you are not revving it at about 4000rpm and barely moving, the clutch will be fine.

Thanks but I done it a few times where the car made a judder noise as I wasnt giving enough gas and my foot was holding down and middle of the clutch repeated process. I am sketpical if it can damage the car or clutch as the judder noise worries me.

It might just have a juddery clutch - it does happen, and can be a symptom of wear, contamination or, heaven forfend, an iffy DMF if the car has one. It doesn't necessarily mean failure is imminent though. I've had a couple of cars that were prone to clutch judder, but I've never actually had to replace a clutch in 40 years of driving.

I agree with the previous answer actually - if you have a tame mechanic, get him (or her) to check it out for you by trying it.

Clutches on used cars are always a lottery - some people can wear them out in no time. There's a gent near here with a Fiesta, only does 2000-3000 miles a year, and has a new clutch at at least every other service!
