Yes, about 65% reduction of particulates, but it produces more nitrogen oxides (NOx), which can be cured with a catalytic converter, but Diesel engines usualy do not have a cc because of the high sulphur content (which makes a cc useless). The 'best' fuel (relatively, of course) is hydrogen and oxygen, but LPG is environmentally friendly as well. To get some more SAAB content; my '79 96 runs both on LPG and petrol. I once did a test with a portable GC on its exhaust, running on LPG and then running on petrol, see http://members.home.nl/saab96/techtip/96GC-LPG.jpg The LPG graph (left) is a flat line; no hydrocarbon emisions, while the petrol graph (right) clearly shows peaks of benzene, toluene and xylene. -- MH '72 97 '77 96 '78 95 '79 96 '91 900i
