Thread: D4 Long Range tanks and fuel usage?

Fuel Consumption - Blank.xlsx

Not really answering the initial question but in terms of calculating fuel consumption I use a "Car Logbook" App on my phone. Not just for recording work journeys etc, I mainly use it for logging fuel fills and therefore fuel actual fuel consumption. Super easy and it will also give a graph over time of fuel consumption and average. Its super quick and easy to use when you fill up rather than having to put things on a spreadsheet later.

and Yes I can't believe how inaccurate the LR average consumption reading is. Never had a car this bad. over 20% out on mine

Give it a go.

thats great to know! I really need to get one I think!

Ditto. I wonder if iiD would do a group buy?

My LoneRanger tank has a separate pump to fill from it to the std main tank, and a bar gauge for fuel level in the extra tank. Works fine as an indicator, and once the fuel is pumped over, the LR gauge works as normal. I use fill to fill for any calculations.

As an aside, have you weighed the D4 with a full tank now you have the reserve tank fitted. I assume you have fitted an external wheel carrier to enable the extra tank to go in. Add a bullbar, and your vehicle weight is getting right up there. I removed a full drawer system and a roof rack once I started towing the van. With around 270 kilos of ball weight, and all the mentioned gear I was in trouble with my GVM. Pays to check.

It is not just the GVM but the rear axle max loading that should be checked. At 1855 kg max you could come close or exceed that with minimal luggage, extra fuel tank and spare wheel carrier at the back. A visit to a weighbridge should confirm your fear or delight. My D4 weighs in at 1420 kg on the rear axle with stock standard, no luggage, only driver and 60 litres of fuel in original tank.

I have the 160ltr long range tank in the D4 2.7L, I use the fill the car and work out the Litres per 100 on how many litres I put in, there's more important things to worry about than few Ks here and there.

I drove to Shepperton a couple of weeks ago, round trip recorded 10.6/100 on the fuel thingy, when we worked it out after refilling the car with litres put in verses Ks travelled, 11. something, I'm happy with that considering the weight of the car and it's shape(a brick) if you want fuel economy, buy a Golf

All my previous cars have had a LR fitted. One of the reasons I did not fit one to the D4 was exactly what StewG states. Also this is reinforced with comments made by Redback on the penalty the fuel extra weight makes on fuel consumption. You will see I have a few mods which do effect fuel consumption, and yet on a country trips similar to driving to Shepperton, I get high 8/100 to low 9/100 depending on wind conditions. IMHO there are only a few times where I could see I (and I repeat I) would really appreciate the extra fuel carrying capacity. YMMV depending on where you go. Have done all the long remote trips in previous vehicles I no longer have the urge to do them again in this vehicle. When towing my off road van, I carry 60 ltrs on it, and have never been short of fuel.... mind you only have done 800kms between fills. But just evaluate where you want to go and do you really need that extra weight and the penalties it incurs on your vehicle. Maybe the cost does not justify the penalties imposed.
