Inquiry (采购产品): intermittent shutting down of enghine I have a 1996 300D benz. Recently the engine will cut off when I am travelling. I took it to the dealer and they could not find the problem. I took it to an independent shop, and they changed the in-line filter and added an additive to the fuel. During the first two weeks it ran great, but now it shows signs of reverting to the past problem. Do you hevan additive that will clean up any wax or gum build-up for my car's engine?
