D24 tic fuel issue
hi all
i have the d24 tic in my 940 volvo it has always returned 30ish mpg since I've had the car 38 mpg on a good run 16 years now just filled up and its calculated 26 mpg most of this milage has been short runs on this tank its the lowest I've had pretty sure I've got no fuel leaks and had new volvo / bosch injectors 2 years ago so would have noticed it by now as i do a calculation at every fill up also been using a shot of millers diesel clean for the last 10 years or so suppose i need to take it for a long steady run you would say I've read somewhere you can adjust this engine a bit to make it more frugal but never touched the pump / timing but did have it checked few years ago and was fine . any comments most welcome |

There's plenty of confusion with regard to measuring fuel economy. The metric system, US gallons and Imperial gallons. Since you own a 940, and are referring to miles, ill assume you are in the UK. 26/mpg Imperial would be a bit low. However winter mileage can be quite dismal. Are fully synthetic lubricants in the engine, transmission and differential? It could as simple as a low quality batch of diesel also.
