Petrol or diesel

[madbopper]

Ok, we have to forget red diesel it doesn't exist in my world,

So let's say I want to buy a 35 hp stumpgrinder what will be cheaper to run a petrol machine or a diesel one, does the diesel plod along and use less fuel, and is the petrol screaming its guts out or would they use about the same as they are both 35 hp .

Would the diesel machine have more grunt or exactly the same as the petrol.

 

My head hurts just thinking about this..

i would say you get more torque from a 35hp diesel and lower fuel consumption than equivalent petrol but you may have issues with it being top heavy as diesels are generally heavier built

Just out of interest... Why not red diesel?

Exactly my thought, red can be bought from a couple of garages near me, I think they take your reg number and ask what your using it for.

Machine will be used in Australia, the fuel is different over there every thing comes straight out of the pump no tax incentive on your red diesel, when I tell the ozzy lads about red diesel they can't get there head around the concept at all.

Diesel and petrol are a very similar price at the pump.

hours of use by difference in fuel consumption (over say 3 to 5 years) compared to, I suspect, a sizable difference in capital cost.

Kubotas are wonderful diesels.

Kohler are equally wonderful torqey petrols, and def lighter, and air cooled.

Could/should you not get a days trial of both machines and access the actual fuel consumption?

Diesel has between 10% and 15% more energy per litre than petrol. With its higher volumetric efficiency a compression ignition engine is more efficient at part throttle than a spark ignition engine.

Cheers diff lock I think you have got it, I will price up both and try to get some facts of the dealers.

kubotas are king of small diesels

Kabota engines seem to run for ever, cant see a petrol engine lasting as long ,imo
