I used to drive 75,000 year, all in Diesels, I now only do 24,000, splite between the van and car, both Diesels,one with 113,000 on the clock, one with 95,000 on the clock, neither burn any oil and run sweet as a nut, if you service them regular, dont thrash the NUTS of them they will look after you well, I changed to Diesels over 25 years ago and would NEVER go back to a petrol.
