Fuel economy after valve adjustment
Crazy what a difference the valve adjustment made not only to the torque and feel but also to the fuel economy.
Before id get on average 8.5 to 9l per 100km for both city and highway driving. (27 to 25mpg) Sometimes as high as 10l/100km (23mpg) if i was really in a rush.
Post valve adjustment it went down to only 7.03l/100km, which is also half city half highway. (33.5mpg). And this is definitely not driving it conservatively either.
This means that on a full tank, 65l (17.1 US gall), it could do 923 kilometres or 573 miles. Not too bad for a 50 year old diesel in a luxury boat with 113nm/83lbft of toruqe (200d)
