My diesel is 2001 and done 75k. A recent trip over yorkshire moors and it used i litre on 1000 miles.I also have signs of leak on chassis leg which is difficult to trace as no drips on floor etc. I have seen a rubber tube behind the rad which appears split and oily. Any ideas.My mpg for the run was 25 which seems to be roughly what everybody seems to get.
Do the the guys with psi notice any improvements on pulling away? mines flat( its an auto) unless i boot it.What are rthe symptoms of a dirty/clogged intercooler is it an easy job/
Cheers.

I bought my car standard and then added the PSI.

It really does make a huge difference, don't think about it, just buy one, it makes the car driveable.

1 litre per 1000 is alot. BUt you should investigate your external leaks and fix them then you can measure what the engine is using.

My engine has done 65k miles and it uses 250ml oil per 1000 miles at present. But lots of things can contribute to oil consumption that do not mean the engine requires any repairs. Old oil, thin and dirty oil, wrong oil.

It IS NORMAL for an engine to use some oil. Some do, some dont!

A pint or so every 1000 miles is reasonable some of this will be being lost through the turbo and is quite normal. One and threequarter pints over that distance is a little excessive. If your vehicle has not had the intercooler flushed at 75k it will certainly benifit from having it done. Maybe a little more power and improved fuel comsumption. Very easy to do, take it off a little fiddly but not that hard, use paraffin first, a couple of pints, give it a good shake with a plastic bag and some elastic bans over inlet/outlet. Do this until next load of paraffin is cleanish. Then if you can get hold of some, use Acetone fill it with this and leave it for a hour or so to cook. Empty this out and put about a litre of Acetone back in and shake it until you go blue. Then empty and give it a good blow out with air line if you have one. Or just leave for half an hour and the Acetone will dry off. Refit intercooler. I got another six MPG after cleaning mine. My vehicle is chipped don't know what make of chip it is was in there before i bought it, but it is truly quick. But the fuel gauge drops as a square of pedal pressure. So if you use the power you WILL use more fuel. Cruising on a motorway however is very good in terms of fuel comsumption with the chip. I find using the cruise control as much as possible definatly helps keep fuel comsumption down, even around town.

Hi, I was thinking of doing this on mine and a mates and was wondering whether 5L of acetone (which can get on Ebay for £9) was enough.

How much acetone does it take to fill on the first fill (when you leave it).

Do you leave it in a plastic bag like tyou do with the parafin at the first stage of cleaning?

Do you have to remove the front and radiator, oil cooler to remove the intercooler?

Cheers

Five litres is plenty, you do not need to fill it to overflowing only so the matrix is full. Acetone evaporates pretty quickly and is of course highly inflammable so it's best to cover the ductings whilst you leave it to do it's thing. Of course if you are going to put Acetone in and shake it around for the final clean you need to seal the ductings or it will be all over you. Wear some rubber gloves and NO smoking. You don't put the intercooler in a plastic bag just seal the ductings with a good strong plastic and some rubber bans or tiewraps. You just keep putting a bit in and shaking it until the Acetone comes out clean there will be no **** left in there by then believe me. But don't forget to clean with paraffin first until paraffin is reasonably clean. First application will be black as the ace of spades. Just take off the slam panel and it will be self evident, you will need a good socket set and hope the bolts are not corroded into the lugs, best get some Easit or Plus gas just in case. Other than that pretty easy about four hours or less should see it done. Good luck.

PS. You can keep the Acetone just pour it into a nylon container, use a funnel with a nylon stocking stretched over it. The crap will settle after a week or so if you then carefully decant it you should have enough with five litres to do both vehicles.

Cheers everyone help much appreciated
