Pete Attryde Posted August 6, 2007 Share Posted August 6, 2007 Can't comment on the towing MPG but the 28mpg sounds about right for that sort of driving. Pete. Quote Link to comment Share on other sites More sharing options...

61a Posted August 7, 2007 Share Posted August 7, 2007 When I first got my 300 TDI about a year ago it was doing around 28 mpg. Since then I have been gradually improving its performance and as a consequence its economy. Removing the viscous fan and replacing it with a Pacet one made a negligable improvement but chucking out the old air filter and fitting a K & N one took the mpg over 30. Recently because of an MOT failure and constant naging from anyone who knew about such things I removed the EGR. At the same time it had acomplete set of new tyres , an oil and filter change and the valve clearences adjusted. Next 500 miles returned 37 mpg plus much improved mid range acceleration. I always use original filters and good quality oil and change every 6 months reguardless of mileage. Last time 3000 between oil changes. About 15 years ago I went on a visit to the Transport and Road Research Establishment and was told by one of their boffins that good quality oil and filters changed at half the manufacturers recommended intervals would result in almost no significant engine wear. Not being a high mileage driver in my own vehicles I have always stuck to this and always achieved well in excess of quoted economy figures. I have spent a large part of my working life scrapping the remains of people and vehicles off the road I suppose I am a bit of a stickler for regular maintainance, correct tyre pressures etc. Jules Quote Link to comment Share on other sites More sharing options...
