You may have stayed away from diesel cars like the rest of North America, because older models of diesel cars were seen as slow, loud, and strong polluters. Things are starting to change, however, as more car manufacturers are shifting to diesel.
Diesel cars have many different benefits. For people taking to the highway often, you should get a diesel car. Diesel cars boast better fuel economy, give better gas mileage, and provide faster acceleration. Even though your diesel engine may not be as powerful as it looks, you will only need to reach certain low speeds to accelerate smoothly.
Despite these advantages, diesel cars are still dirty. Good thing that new technology has brought a way to remedy that. Automakers have cut down the dangerous nitrogen oxides diesel cars emit using selective catalytic reduction (SCR) systems. SCR uses a fluid called diesel exhaust fluid (DEF) which converts the NOx emissions into harmless nitrogen and water particles.
What is DEF?
DEF consists of urea and deionized water. You will have a separate tank for DEF which you have to fill up every so often. Diesel cars with DEF often have gauges that tell you if DEF levels are low.
DEF does not Last Forever
You can refill your DEF tank at auto shops or truck stops. You can also do it manually at home. Some auto stores sell DEF in small jugs or large containers. When refilling manually at home, you need DEF fluid pumps that you need to buy as well.
Added DEF Benefits
Besides environmental benefits, DEF-fitted cars have been tested to have better power, lower maintenance requirements, less engine wear, and better engine combustion. The only downside you’ll encounter will be the higher price of DEF-fitted cars.
Gasoline may still be king in the U.S. but diesel is starting to rise. Perhaps you should make the switch from gasoline to diesel too if you want to enjoy the benefits of diesel cars with DEF.
