How pinching pennies at the pump, could cost you thousands...

If you’re like most of us, chances are you don’t think twice about where you buy your gas, as long as it’s cheap, convenient, and offers super-sized drinks for all of 69 cents. And that’s a big-time problem these days.

Gas stations are all about price and volume, and cheap sells. Unfortunately, when it comes to most modern cars, using cheap off-brand gasoline can also cause expensive problems -- the kind that can be chronic, and deadly for your car's engine.

Here in the United States, engines are now experiencing higher levels of failure -- along with more fuel related issues -- than they were just a few years ago. That means that your reliability is getting worse... but the manufacturers who designed your engines aren't the ones to blame.

The problem is simple, new generations engine are much more complicated now a days due to the GDI Technology.

GDI or, Gasoline Direct Injection is a type of fuel injection used by many modern vehicles. Traditional multi-point fuel injection injects fuel into the intake at low pressure. With GDI engines, a common fuel line injects gasoline at high pressure directly into the combustion chamber of each cylinder. This gives GDI engines precise control of injection timing and the amount of fuel delivered.

GDI engines provide many benefits that conventional fuel injection can’t. With gasoline direct injection technology, you can draw more power from smaller engines. In addition, your car gets improved fuel efficiency and reduced emissions. While great, the power of the GDI engine is a double-edged sword. While you get many benefits from gasoline direct injection, carbon deposits that build up can steal all the positive associated with this type of engine.

A bunch of manufacturers got together and developed a performance standard for gasoline called Top Tier. Dozens of retailers, from Amoco to Valero, get their gasoline additive packages inspected for their ability to keep your engine clean and free of metal contaminants. A recent scientific experiment conducted by the American Automobile Association, yielded some pretty clear-cut results. When comparing Top Tier with non-top tier gasses in a controlled environment, "non-TOP TIER gasoline caused 19 times more engine deposits than TOP TIER brands after just 4,000 miles"

If you use Top Tier gas and follow the maintenance schedule, a direct injection engine can potentially save you well over $1,000 in fuel savings and greatly improve every aspect of your driving experience compared to a non-DI engine. So do yourself and anyone that owns your car after you a favor: invest in your vehicle.

The truth is that these engines can be just as reliable and far better to own than their non-GDI alternatives, provided you use Top Tier gas (more on that in just a second) instead of the cheap stuff. How important is gas quality? I checked with Rebecca Monroe, Senior Fuels Engineer at General Motors, who told me "proper gasoline detergency is necessary for keeping engine components free of deposits in direct injection engines." In other words, Top Tier gas contains a lot of additives and detergents designed specifically to keep a DI engine clean, in good working order, and reduce the quantity of fuel deposits. Direct injection engines are very sensitive to the fuel you use.

Stop yourself from expensive vehicle repairs, and any future problems with your car by simply filling up at Top Tier Gas Stations such as, Exxon, Shell to mention a few.

Make sure you bring your Vehicle for periodically Check-Ups with Auto Clinic International to make sure your vehicle is always running its best.
