Fuel Economy

Clean your EGR

new-tires-vs-old-tires

Benton Harbor drivers realize it is pretty amazing how auto makers have been able to consistently build more powerful engines in vehicles that get better fuel economy while at the same meeting increasing environmental standards. One of the little miracles that helps make this happen is the Exhaust Gas Recirculation (EGR) Valve. The EGR valve routes some exhaust back into the air intake system in both gasoline and diesel engines. The exhaust gas takes up some space in the engine cylinders, replacing some of the oxygen-rich air that would otherwise be in there. This means that the fuel burning event is cooler. Cooler combustion means fewer harmful nitrous oxides are produced.

Your EGR valve can get gummed up, messing up the timing and amount of exhaust that is supposed to be recirculated in the engine. Symptoms of EGR valve problems are rough idle and poor engine performance. Performance can be restored by cleaning or replacing the EGR valve, depending on how dirty it is.

EGR valves in diesel engines are particularly susceptible to becoming clogged because of the high soot content in diesel exhaust. (Note: the soot is ultimately filtered out of the exhaust further down the exhaust system, but not before it passes through the EGR valve.)

There are a couple of things you can do to lengthen the life of the EGR valve in your diesel engine. First, extended idling allows for more soot buildup because the engine operating temperature is reduced as it idles; the valve is not opening and closing, allowing particulates to accumulate in the valve. Next is fuel quality. Diesel fuel has a cetane rating: the higher the rating, the better the combustion will be. Unfortunately, the cetane rating is rarely posted on the pump and can vary from location to location. Adding a cetane booster to the fuel tank can help with this.

So, if you are experiencing rough idling or poor performance in your gas or diesel vehicle, have one of our Pro Muffler & Brake Shop expert technicians diagnose the problem. They can set things right and restore your vehicle’s performance.

Is it time to check your fuel pump?

Pro Muffler Anti-Lock Brakes
Pro Muffler & Brake Shop Inc Tech Question:
Is it time to check your fuel pump?

Pro Muffler & Brake Shop Inc Tech Answer:

Your fuel pump sends fuel from the fuel tank to the engine. Fuel pumps just wear out over time: it might be the electric motor, a sensor, a valve, or a relay or some other electrical component. Whatever the exact cause for the fuel pump failure may be, the solution to getting you back on the Benton Harbor road is to replace the pump assembly. When one component has failed, another one is probably just around the corner so it makes sense to replace everything at once and save the future labor costs.

The fuel pump is inside the fuel tank on most vehicles, and for many cars, trucks, and SUVs, the fuel tank must be removed to replace the fuel pump. As you can imagine, that is pretty labor intensive: removing heat shields, retaining straps, all of the EVAP lines, fuel lines, and electrical connections. And of course, there is properly and safely handling the fuel that must be drained from the tank.

Some vehicles have an external fuel filter that should be replaced at the same time. The fuel tank may need to be replaced on some vehicles because of design specifications or if the fuel tank is corroded or otherwise damaged.

Now there are a couple of things you can do to help your fuel pump last longer. One pump killer is contamination in the fuel tank. Sometimes this comes from the fuel itself. Buying fuel at a reputable station will help make sure you are putting clean fuel into the tank. Older vehicles tend to have more sediment in the tank from years of rust or corrosion from the tank itself. The tank may need a thorough cleaning or replacement.

Another thing you can do is refill your tank when it gets down to about a quarter full. The fuel pump is submerged in the fuel which cools and lubricates it. When the tank runs low, the pump has to work harder to suck up the fuel from the bottom and there is no fuel to cool it. This can lead to premature wear.

When the day comes that your fuel pump needs to be replaced, Pro Muffler & Brake Shop Inc in Benton Harbor will use a quality replacement pump that meets or exceeds your vehicle manufacturer’s specifications. The entire assembly should be replaced. We’ll be sure to install a replacement pump that is compatible with your fuel type. For example, if you have a FlexFuel vehicle that can run on gasoline with up to 85% ethanol content, your fuel system components – including the fuel pump – must be able to withstand the corrosive effects of high alcohol content fuel.

PCV Valve Replacement

Pro Muffler PCV Valve Testing
Pro Muffler & Brake Shop Inc Tech Question:
What is a PCV Valve and should I test it?

Pro Muffler & Brake Shop Inc Tech Answer:

The PCV valve is a little, inexpensive part that does a big job for Benton Harbor and our environment here in Michigan. PCV stands for Positive Crankcase Ventilation. The crankcase is the bottom area of the engine that holds the oil. When the engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause engine corrosion. At high speeds, the pressure can build up to the point that gaskets and seals start to leak. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and reduced .

Fortunately, it’s very easy to test the PCV valve and quick and inexpensive to replace at Pro Muffler & Brake in Benton Harbor. Even so, it’s often overlooked because many people in Benton Harbor don’t know about it. Check your owner’s manual or ask our friendly and knowledgeable technicians at Pro Muffler & Brake. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

Please ask us at Pro Muffler & Brake about your PCV valve. For the price of a couple of burger combo meals at your favorite Benton Harbor drive-up window, you can avoid some very expensive deep engine repairs.

Improve Fuel Economy

fuel_gauge_01
The US government has a website dedicated to helping use less fuel. It presents the cost savings in a way we can all relate to, no matter what kind of vehicle we drive. Here’s an example: Having your engine properly tuned, can save up to 4%. If you’re paying one-fifty for a litre of gas, you could save six cents a litre.

Replacing a faulty oxygen sensor can improve fuel economy by up to forty percent. That’s a huge savings per litre.

Chances are that if your oxygen sensor is kaput, your check engine light will come on. Now, there’s any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it’s on, it’s to get it checked out as soon as you can. Talk to your friendly and knowledgeable Pro Muffler & Brake Shop Inc .

Here’s an easy one – inflate your tires to the recommended pressure. That could save three percent of a litre. Even a little drop in pressure will hurt so check your tires every week.

Your vehicle manufacturer has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced fuel efficiency, or up to six cents a litre.

Here are some free gas saving tips from Pro Muffler & Brake Shop Inc: Don’t drive aggressively, drive within the speed limit and remove excess weight (junk in the trunk) from your vehicle. These can add up to quite a bit per litre.
