this engine is not the most economical as a lot of you will know but its very reliable for me and the 940 estate is ideal for my job as a carpenter .
i get millers diesel clean in 5 litres and put in 20mls to 60 litres fuel .
i did try shell fuel but i could not get a real increase in fuel economy .
but I've always used the same additive

What was the issue with the injectors ?? If you used a good fuel additive (Most products from Millers are good) it's unlikely to have been caused by gum deposits (Half of all injectors sent to a Bosch service center are just gummed up and could have been cleaned with a direct feed cleaner or even in-tank fuel additive).
The half life of a Bosch injector in set terms is about 300K miles, so if the tips were reported as blown it might have been caused by non Volvo fuel filters, or bad luck.
If you do the occasional UOA (Used Oil Analysis) it's easy to see if the injectors start to gum up, as the fuel contamination figure should be zero during the summer, with a potential trace only during the winter. Doing that once a year saves on the cost of using a fuel additive.

hi i got 6 genuine injectors of ebay for £70 in the blue volvo bags old stock brand new selling them off so thought that was a better way to go than having the old ones refurbished cheaper too . yes miller is good . i have only ever put millers xfe and vw oil filters on since I've had the car 14 years now changed at 5000 miles

Filled up with 40L off Tesco Diesel on Saturday morning and have done 430 miles since. My trip computer was showing 42.3 average MPG as I pulled up at home this evening. Thats about what I would expect on 2 days of long motorway runs.

Your Fuelly results for 9/8/2014 say you filled up with 50L of Tesco fuel and achieved 31mpg, motorway driving. That's not very good for a 2009 1700kg V70.

My 2004 2655kg XC90 regularly achieves over 45mpg on motorway journeys using normal Esso diesel.

6 new injectors for 70 quid!!
Now that's one hack of a Fleabay steal.

VW oil filters are good, BUT which fuel filters did you use ??

My friends father is a HGV driver, delivers fuels, mainly heating oil.

The reason I mention this is because he told me about "Cracking", a controversial way of producing fuel that results in diesel/petrol with a very low cetane number/RON that is most often sold by supermarkets. The better fuels, higher cetane/RON, distilled from crude are usually snapped up by the big brands, BP, Shell etc..
The cracked and crude are often mixed to varying degree's and sold as mixes but again the lower cetane/RON stuff is brought then sold by supermarkets.

Testing a fuels cetane number is a difficult process so lower than the EU standard(51) is often sold to the public as additives such as cetane boosters are expensive.

First, the link shows in US units for some reason, you need to go to the top left corner near the car name and change to UK MPG.

Secondly, I enter the information of the fuel put in at that stop. Saves me having to remember what I put in when I last fueled up. So for the tank you quoted it, it was actually BP regular diesel.

Thirdly mine is a 185bhp D5 which is often said to have worse consumption than the earlier 163bhp D5.

And lastly, it is a geartronic.

ps, I had mine on a weighbridge and it was 1,860kg.

Have you added half a tonne of lead to your car? The best figure I can find for a 2004 XC90 D5 is 2113kg.

Well I've just fueled up after the mostly Tesco Diesel tank of fuel and achieved 42.3 MPG. My best ever result on Fuelly. That consisted of 3 days of mostly motorway driving. A total of 510 miles.

• Manchester to Stoke and back.
• Manchester to Birmingham and back. Came back via Cheshire A roads due to a congested M6.
• Manchester to Leeds and back.

Not too bad!

Long trips sometimes clean the injectors up, which can result in a better spray pattern and resulting fuel economy. The exhaust system also gets cleaned out, apart from residual ash and that also helps.
