December's Pemex fuel prices

navigator: Very interesting. Sometimes after finding one brand to be bad you may find that the problem is local. In some areas there is only one refinery and all brands use the same fuel. The additive package is different. Where I live in Canada the small engine repair shops all say: NEVER USE SHELL. But maybe we are imagining this as Tepetapan says that fuels are made to some international standard !!!!!!!!!! " Pure Nonsense"!!!!
