Gas Versus Diesel

by Judy Phan

Cost - Due to the high compression ratios and resulting high cylinder pressure in diesel engines, they must be built to withstand a lot more punishment than gas engines. The parts that are spruced up include a thicker block and cylinder heads, pistons, crankshaft, and valves, which can be very costly indeed.

So when talking about the cost, it's the gas becoming triumphant. In fact, the number of people preferring gas is higher compared to those opting for diesel due to the price.

Fuel price - Diesel gas is the winner regarding this issue. Since the refinement in diesel fuel is easier, it is usually cheaper as well. Nevertheless in the United States, diesel may have the same price or a little bit cheaper when compared to unleaded gas.

Noise & vibration - When this is the topic, the trophy goes to gas. It's unfortunate that vehicles using diesel engines still produce a lot of sounds and vibration even until today. Even when it's motionless, the shaking of vehicles using diesel is still obvious while you can't even distinguish which among those gas vehicles are running or not.

Cold weather - This is another loss for diesel engines since it is easier to start gas engines during cold weathers. That's because gas engines have those spark plugs which aren't present on diesel engines. During cold temperatures, the air within diesel fuel is not yet that hot, hence, making it difficult for a diesel engine to start.

Maintenance - Maintenance on a diesel vehicle is more expensive, thanks to many things including the larger volume of oil in the engine and the fact that fuel filters and water separators must be serviced more often than gas vehicles. Gasoline engines have a bigger advantage due to extended service periods on spark plugs, engine oil, and even antifreeze.

When choosing between diesel and gas, it's important to assess the place to where you live and the purpose of the vehicle. Gas vehicles are suitable for quick accelerations. But if your vehicle is utilized for carrying extremely weighty objects and you'll be traveling greater than 100,000 miles, a vehicle using diesel engine is more recommendable.

Gas runs smoother, fuel is easier to find, and they are easier to start in cold weather. On the other hand, if you plan to tow, value good fuel economy and plan on racking up a lot of miles, then you'll want to buy a diesel.

In terms of price, it's always the diesel engines which are more expensive. But if you have a large budget and the price is not a problem to you, the best choice would have to be diesel. When buying one or more trucks, it's also preferable to go for diesel especially when hauling colossal and heavy objects.
