Exmoor Beast Posted July 13, 2012 Share Posted July 13, 2012 I have a project on the go that is a tad remote, like an hours round trip over bridleways/open moorland/river crossings etc Somehow I need to justify the costs of using the 110 for this. I'm guessing the AA recommended 40p per mile is a bit off The Land Rover is a 200tdi, so if I was to say at 50mph it did 25mpg it would use 2 gallons an hour. So if I am doing an offroad trip that is an hours return journey that is 2 gallons of fuel. I still use 40p/mile for charging my clients so if you were to go back to the 50mph thing you'd be looking at £20/hour Do we reckon that is fair or am I way off and should be thinking about factoring in a new set of superpro bushes and a complete change of fluids over the project?

CwazyWabbit Posted July 13, 2012 Share Posted July 13, 2012 Well the government recommends 45p a mile for private car used for business travel so you are undercharging http://www.hmrc.gov.uk/paye/rates-thresholds.htm#8 Quote Link to comment Share on other sites More sharing options...
iomlt Posted July 13, 2012 Share Posted July 13, 2012 you charge people to take them on public rights of way???? Quote Link to comment Share on other sites More sharing options...
Exmoor Beast Posted July 13, 2012 Author Share Posted July 13, 2012 you charge people to take them on public rights of way???? No. What gave you that impression? I am working on a project that is 1/2 hours drive offroad from the nearest tarmac and need to factor in costs and have some justification in place for audit purposes.

missingsid Posted July 13, 2012 Share Posted July 13, 2012 What does it work out at if you use the low ratio x gear x the 45p? ie. very rough but in low box half speed per rev then double the consumption? This could still work for high box as you are going to be in a lower gear than you would on road? Marc. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted July 13, 2012 Share Posted July 13, 2012 My V8 did 6 - 8mpg off road compared to 17 on road. If you are in low box for this trip I reckon you could easily double your fuel costs. Quote Link to comment Share on other sites More sharing options...
zardos Posted July 13, 2012 Share Posted July 13, 2012 My old V8 did 2gpm offroad, 16mpg on road Quote Link to comment Share on other sites More sharing options...
zim Posted July 13, 2012 Share Posted July 13, 2012 Challenging we use about 8 - 10 litres an hour. Thats constantly in low box in a tuned 4.2 rv 8. G Quote Link to comment Share on other sites More sharing options...

Mutz Posted July 15, 2012 Share Posted July 15, 2012 My old V8 did 2gpm offroad, 16mpg on road 2 Gallons Per Mile, now that is thirsty!!!!! Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted July 15, 2012 Share Posted July 15, 2012 Greenlaning I don't tend to notice a difference over a day's outing from normal performance. Quote Link to comment Share on other sites More sharing options...
zardos Posted July 15, 2012 Share Posted July 15, 2012 2 Gallons Per Mile, now that is thirsty!!!!! Well it usually was 6 hours of extreme offroad per tank in underdrive low range Quote Link to comment Share on other sites More sharing options...
Ruuman Posted July 15, 2012 Share Posted July 15, 2012 Diesel defenders are very frugal off-road, if your on lanes and semi made tracks your probably not going to exceed 30mph and I suspect a fair bit will be in high box anyway. I think you would be safe assuming 20mpg. Though like James, I don't notice much difference road to offroad. I just spent the whole weekend at a festival moving bands about and recovering VW campers, probably burnt 15-20 quid's worth of diesel and the truck was running for 50% of the day at least, but it was all very low speed and revs most of the time. But you do want to factor in a higher cost as obviously there is a lot more wear and tear on the truck, especially tires. Don't forget the 20quid to pay the local farmer to pull you out when the inevitable happens too! Quote Link to comment Share on other sites More sharing options...
g&t Posted July 16, 2012 Share Posted July 16, 2012 2 Gallons Per Mile, now that is thirsty!!!!! Especially when compared to a Centurion tank (27 litres & 52 tons) official off-road consumption of 0.38mpg!! Quote Link to comment Share on other sites More sharing options...

smokinv8 Posted July 16, 2012 Share Posted July 16, 2012 Hmm, I find with mine that when I'm out greenlaning I use less Diesel than on road useage. Most of this is due to being in low range and covering most of the ground at not much more than tickover. Quote Link to comment Share on other sites More sharing options...
ThreePointFive Posted July 16, 2012 Share Posted July 16, 2012 I doubt that. Even in my V8 I used to wonder how I'd used so little on a whole day, the answer being I had travelled all of 5 miles. It just seems better because you're using less fuel per hour but more per mile. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 16, 2012 Share Posted July 16, 2012 Is there not a running time/fuel consumption chart in the book like there is in the Series green bible for when the vehicle is used off-road or as a static engine? Don't have it to hand but it could be a good reference point. Quote Link to comment Share on other sites More sharing options...
Davedef90 Posted July 17, 2012 Share Posted July 17, 2012 When it comes to billing the client, fuel economy has nothing to do with it. You can harge up to 45p/mile as stated above. Anything less then gets offset later on tax return. Your shocks/bushes/oil etc can be billed to your company if it is a company car. They should not form part of the charge to the client. Thinking about it not sure you can combine the 45p/mile and repair costs as 1 relates to private car and the other to company car. You have to work out which system is better for you in the long term Quote Link to comment Share on other sites More sharing options...
Exmoor Beast Posted July 17, 2012 Author Share Posted July 17, 2012 Cheers for your input folks. I've cracked it now thanks to a mate who is in the know. Its not as straightforward as applying a mileage rate but it means I have a means of quantifying the cost of operating the 110 for the purpose in hand.

JST Posted July 25, 2012 Share Posted July 25, 2012 although you have sorted it one of my tgv's does about 4-6mpg off road. so V8 territory! Quote Link to comment Share on other sites More sharing options...
