hi dirty windows am shocked that you get nearly 600 miles with a full thank your scudo must be someting special to do that many miles i got the dispatch 2.0 ltr hdi since new 07 plate and never ever had no more than 350 miles please please begging you tell us the secret
well i do cart a 650l tank and the wife, make sure you change your fuel filter every 9 months, and air filter, ive just done that as my tank crept down to 500miles a tank, not too sure if changing the oil and filter makes a difference.
i have taken my roof rack off as well, so that will give me an extra 5-10% hopefully!
i do rag it as well, but going to slow down and see if i can get 700 out of it! you know how it is though, always rushing trying to get the jobs in!
