I'm a big fan of Diesel powered vehicles, and I've been around Diesels a lot, but I can't figure out how General Motors got their Diesel Engines to run so quiet in their consumer grade pick-up trucks? I've asked the Dealers and even some GM truck owners, and no one has given me a satisfactory answer. Is there anyone on here that knows the secret? It must be patented, because no other Diesel engines I've heard run as quiet.
