Six Tips For Diesel Engine Beginners

Modern diesel engines are a feat of engineering, combining impressive power with fuel efficiency. Their environmental friendliness and fairly low maintenance have been the cause of their long-time popularity in Europe, and they are recently beginning to become more common in the U.S. Given the slew of benefits they carry, diesel engines may quite possibly become more popular than gas engines someday. If you're like most U.S. drivers, you're probably not very familiar with diesel engines. Here are some tips to get you introduced.

1) Nearly all new diesel engines come equipped with a turbo-charger. Think of a turbo-charger as a jet engine - it forces outside air into the engine and increases efficiency and performance. Turbo-chargers are very powerful, so great care must be taken to make sure the air entering the turbo-charger is clean and clear of debris. Therefore, it's important that the air filter on your diesel is clean and changed often. Most manufacturers equip their vehicles with electronic sensors that will tell you to check or replace your air filter, and when this sensor tells you to change the air filter, do so immediately. If you ignore this warning, you could damage your engine.

2) Diesel fuel isn't as clean and pure as gasoline, so the fuel filter in a diesel engine is very important. Again, your car has sensors that will warn you if the fuel filter becomes clogged, and you should react to these warnings quickly. If you fail to change a clogged diesel fuel filter, it could leave you stranded on the side of the road. Also, keep in mind that diesel fuel filters need to be changed a little more often than gas fuel filters, so don't be surprised if you have to replace your diesel's fuel filter ahead of schedule. That's perfectly normal.

3) Here's some shocking news for new diesel owners -- in addition to being less pure than gasoline, diesel fuel also contains water. Even though small amounts of water will not hurt your diesel engine, nearly all modern diesels are equipped with water/fuel separators. Depending upon your vehicle, you may need to purge the water from your diesel's fuel system manually. Check your owner's manual for instructions on how to do this and to find out how often it should be done. The good news is that many service facilities will perform this task for you at little or no charge, and will also dispose of the water/fuel mixture in an environmentally friendly way.

4) Diesel engines generally burn some of the engine's lubricating oil during normal function. This is why they've earned the nickname "oil burners", and why it's important to check your engine's oil level between oil changes. Let the engine cool for at least 30 minutes before checking the oil, and make sure the vehicle is level. Refer to your owner's manual to know when you need to add more oil, based on your dipstick reading.

5) Diesel engines don't like cold temperatures. At low temperatures, diesel engines tend to start harshly and warm-up very slowly. At extremely low temperatures (below -10 F) diesel engines may not function at all. Thus, it's very important to remember to use your diesel's block heater if outside temps ever dip below zero. The block heater is nothing more than an electrical plug on your car that uses your home's electricity to keep your engine warm, and it's as simple as plugging your car in at night. If you can afford the electricity, you can plug-in your block heater any time the outside temperature dips below freezing. This will protect your engine and make for quick and smooth start-ups, and it will help your engine warm-up quickly. Check your owner's manual for your block heater's location.

6) While all new engines have a short break-in period, new diesel engines usually have a break-in period that lasts 500 or 1000 miles. (Check your manual to find out.) Usually, the manufacturer recommends that you avoid driving at sustained speeds (i.e. long trips on the highway) during this period. Additionally, most manufacturers suggest that you not tow or haul anything during this period. Once the initial break-in period is over, it's not uncommon for your diesel to continue to improve in power and efficiency for the first 20k or 30k miles. Unlike gas motors, which often stop improving in power and efficiency after 3k to 5k miles, diesels need lots of time and use to reach their peak efficiency and performance. In fact, most long-time diesel owners will tell you that their engine didn't really start to truly perform until a year or two after they bought it.

To summarize, it's very important that new or first-time diesel owners review their engine manual. In addition to normal vehicle maintenance, diesel owners should keep a close eye on their air and fuel filter warnings, they should always check engine oil between oil changes, purge water from the fuel system as required, and remember to plug in the block heater any time outside temperatures drop below zero degrees Fahrenheit. When you do all these extra tasks, your diesel engine will reward you with power, great fuel economy, and 200,000+ miles of good service.
