I've read that some diesels and some injection pumps don't work well on SVO or WVO - is this true?
Lucas/CAV pumps are reportedly the most likely to fail on SVO. It seems they are subject to high wear rates and have some components that cannot withstand the higher viscosity of SVO (even heated, SVO is thicker than diesel fuel).
However, many people use a cautious approach of very fine filtration and thorough heating, and have not experienced failures. The Lucas/CAV would almost certainly not survive long with a single tank system, where the engine is started on SVO . By contrast, the Bosch inline pump as found on older Mercedes engines seems to be especially tolerant of SVO.
