Absolutely nothing to do with scientific analysis of diesels but purely a personal observation.
I do not like diesels, anybody that lives or lived in an area of traffic concentration would know of the choking sensation of diesel fumes especially on cold mornings.
Back in the 1960's I drove a BMC LD Mothers Pride bread van, if the beast broke down, it meant quite a wait whilst the mechanics came out, One day, being only a couple of miles form the depot, the pipe from the lift pump to the injector pump cracked. As the engine was still running, I drove back to the depot and the pipe was fixed. In just a couple of miles the fumes were quite nasty. That evening, I was taken ill, very ill. Dr came to In laws where we were for the evening he was foxed. It seems despite his best diagnosis of it being a stroke, he was not happy. The long and short of it was that I was suffering from diesel poisoning. I will admit to being very scared as my brain was fine but nothing would work, I was completely paralysed. I made the vow, never a diesel. It seems now that the lovefest with the diesel might be over.
