	looked at books that came with my lt when new (diesel) it gives some figures for a petrol engine, but only what they call passenger car (kombi) ,there`s none for a truck because of the different combinations you can have in height width etc, anyway a bit winded but here goes, this is for petrol only 143 bhp,105kw, 4 cylinder 2295cm compression 8.8 oil with filter 8.9ltr vw500.00 high lubrication oils vw501.01 multigrade oils fuel consumption regardless high roof or standard lt35 urban 20ltrs per 100km extra urban 11ltrs per 100km total 14.3 ltrs per 100km these are regardless if you have axle ratio 5.286 or 4.857 the co emission in g/km is 329 the lt28 had an extra axle ratio of 4.375 which gave urban 17.8 ltrs per100km extra urban 10.4 ltrs per 100km total 13.1 ltrs per 100km the other axle ratio`s figures on the lt28 are the same as lt35 hope this helps and not confuse, any thing else just ask

	Expect a diesel to be 10-15% better than a similar petrol vehicle at motorway speeds. Its at part throttle the diesel that the diesel is so much better. Get the compressions checked so you know its worth working on, put it back to standard ditching the present LPG and have a good tune up and recheck figures before working out how much new LPG will cost and how long to pay for itself.

	....Eyup...right a few months down the line now...have had the head done on the engine and new LPG pump and system fitted...LPG prices at the mo here are £2.50 per gallon so in effect doubling my mpg at around 32-35 consistantly at 'normal' petrol prices....cool !!!

	they are good figures (32-35), you`ve added 10+ to your original average figure, and with fuel at £2.50 a gall you will soon be quids in, whats the power like, and have you driven her fully loaded yet

	Think you'll find the Andy means he gets 32/35 per £5 spent, e.g. every 2 galls of LPG (1 gall petrol price) not 32/35 per 1 gall of LPG, so it'll take him just a bit longer before he's 'quids in'. but he will get there pretty quickly given the mileage he does,
