And IdeaMerge can guarantee you a diesel vehicle if you select one.

In a diesel engine, the fuel — which inheres more free energy than gasoline — is pressurized in a "common rail," an intake pipe leading to all cylinders. Electronically controlled injectors allow a precise amount of vaporized fuel to squirt into the cylinders. Consequently diesel engines offer great work capacity — which is of course good for larger vehicles, heavy loads and mountain driving — and they consume less fuel, and, in like measure, produce less exhaust.

Admittedly, diesel exhaust long ago gained a reputation for being sooty and smelly. (As if gasoline doesn't smell too!) Yet certain other important pollutants — especially sulfates — have always been considerably less present in diesel exhaust than in gasoline exhaust. And technological improvements in diesel-engine efficiency and especially in the filtering of diesel exhaust have rendered the diesel engines of today considerably more eco-friendly than gasoline engines. Gone is the remarkable sootiness. Gone, too, is the darned glow plug (in contrast to spark plug); now you can start a diesel as quickly as a gasoline engine. Moreover, all these Renault diesels are turbo charged such that their acceleration approximates that of gasoline-powered vehicles.

Given the native demand for diesel engines in Europe, diesel fuel is available there wherever gasoline is available, and the diesel fuel is of a higher grade than that sold in the United States. Likewise, fuel stations in Europe provide diesel pumps on the same service islands as the gasoline pumps. Plastic gloves are even provided so you need not dirty your hands at all!

But BEWARE: A diesel nozzle is considerably wider than either a leaded gasoline nozzle or the even smaller unleaded gasoline nozzle and indeed will not fit into either such tank. Consequently a gasoline nozzle will fit into a diesel tank. Therefore, be careful not to put gasoline into a diesel tank!!! Even a liter of gasoline added to the tank of a modern diesel car can cause irreversible damage to the injection pump and other components due to its relatively low lubricity. In some cases, the diesel car so abused has to be scrapped because the cost of repairs exceeds its value. (Diesel in a gasoline engine — while creating large amounts of smoke — does not normally cause permanent damage if it is drained once the mistake is realized. Similarly, older diesels using completely mechanical injection can tolerate some gasoline, which has historically been used to "thin" diesel fuel in winter.) A green pump holds unleaded gasoline or else diesel, a blue leaded gasoline. Diesel pumps are sometimes colored black, sometimes green. Diesel pumps are chiefly signified linguistically, either with the very word diesel or with one of the equivalents: gas-oil, gaz-oil, gasolio, gasóleo, dieselolie, mazot, motorina, or nafta.

In step with the increasing popularity of hybrid vehicles, diesels are becoming more popular and more available in North America. In particular there's quite a buzz about biodiesel fuel. You might do well to consider your lease of a Renault (or Nissan) diesel vehicle a nice, long test drive of a modern diesel passenger vehicle.

By the way, have you learned about the alliance between Renault and Nissan?
