I have been posting about the stalling problems I had with my 96 SP. A mechanic told me I may have been using the wrong oil in the injector tank. I put Pennzoil synthetic TCW-3 in the oil tank. He told me to add that oil directly to the fuel tank at 50:1 ratio and it looks like it solved the problem. Did I use the wrong oil? Is there oil specifically just for oil injectors. If so what kind should I use?
