When should a car go for a "tune up"?

    Howaya?

    Watching Top Gear the other night got me thinking - what bhp is my car running off? Its supposed to be 100, though the car is almost 8 years old.

    For those that didnt see the show, Top Gear bought a Renault Avantime 3.0 V6 that should have been running over 200bhp. When put on the rolling road it was closer to 150bhp.

    What, other than standard servicing, can keep a car running at its best? Changing the distributor cap and cables?

    Any thoughts appreciated...

    Fuel additives?

    Wouldn't a rolling road measure power at the wheels, whereas quoted output is at the crank but net of ancillaries?

    Valid point, overlooked that.

    Any other ideas on keeping bhp up? Is it just plugs/air oil and fuel filters?

    I'd say it's basically down to replacing anything that has worn.

    Correct for most cars.

    But when they did a service on the car it got back up to 206bhp and AFAIK it was supposed to be around 220/230bhp

    The Avantime puts out 210 from new. I think to be within 4 bhp after 6 years is doing well.

    I was amazed a service upped it by 50bhp (and moreso that it could lose and gain so much from changing/not changing oil, filters and plugs.

    Thanks wasn't paying much attention to the original bhp.

    It was quite shocking, but I think they did more then a standard service. I think they mentioned doing something to the head, maybe gas flow, and a few other bits and pieces

    Didn't they do injectors on it and a few other bits out of the norm service?
