We’re all carefully watching the price of gasoline fluctuate throughout the year, attempting to balance our budgets with the necessary fuel funds we may need for this month compared to last.  However we might balk at the price these days, there are those who can look down at diesel and be thankful they aren’t paying that amount. But are the extra few cents worth it? Diesel has long been renowned as the more efficient, more performance driven, and more durable fuel choice for those who want and need the extra power in their SUV or truck–but why?  What is the difference between gasoline and diesel performances, and do the benefits outweigh the higher price?

More Bang For Your Buck

If you’re going to be towing big weights, diesel is hands-down the answer for you.  Big hobbies such as boating, RVing, or car restoration, or simply requiring large payloads or equipment for your job, pull tremendous loads behind your vehicle.  Diesel’s higher compression ratio within an engine’s cylinders gives greater torque and power at lower rpms, supplying a 17:1 feedback compared to gasoline’s 9:1 ratio.  While a gasoline engine may suffice for the weights your chores or job might demand of your vehicle, they aren’t designed to constantly take the strain towing large loads takes on the powertrain.  According to our technical sources at Rochester Hills Chrysler Jeep Ram (Rochester Hills, MI), demanding such performances out of a gasoline engine will significantly reduce your engine’s durability and life expectancy.  It also uses a substantially greater amount of fuel to tow with gas compared to with diesel, bringing us to our second point:

More Miles For Your Money

A diesel engine, on average, runs thirty to thirty-five percent more efficiently compared to a gasoline engine, well balancing out that initial hike in cost while fueling up.  Consistently, diesel trucks provide greater EPA rated miles per gallon city/highway driving. This is also because of diesels higher compression rate, using less fuel to generate the same amount of power outputted by gasoline combustion.  This is referred to the fuel’s energy density, with diesel measuring in at thirty-five to forty megajoules per liter and gas measuring thirty to thirty-five megajoules per liter. Engines burn leaner and cleaner, too, resulting in less emissions.

More Sense For Your Cents

An SUV or truck is always an important investment in your life, taking into account your job needs, family needs, and power needs now and into the future.  So you want a vehicle that will last a long time, as well as retains good value for years to come should you ever need to trade in for a power upgrade. Diesel engines deal with greater forces compared to their gasoline counterparts, and so their parts are engineered sturdier to take a lot more strain.  Not only that, the delivery of higher torque numbers at lower rpms make for less wear and tear through the rigors you might normally put your vehicle through. Diesel is also less corrosive compared to gasoline, ensuring that your fuel lines and exhaust systems will remain in good condition for longer. Thus, a properly maintained diesel engine will last for, on average, 100,000 more miles compared to a gasoline fueled powertrain.  These reliable systems, therefore, resale for a higher price even with a large 100,000-plus amount of miles compared to gas trucks and SUVs.

It’s an easy matter of assessing your needs now and in the future on whether you should opt to go diesel on your next vehicle.  Gasoline engines are perfectly reliable and fuel friendly for those who have a more casual way of living life, but if you love to haul around a bunch of big toys or you need an extra edge of performance and towing prowess for your business, then diesel will dutifully pay you the extra fuel costs with unbridled power and lifelong durability.
