Is Cheap Gas Bad for Your Car?


GM Auto Tech is always on the look out to help our customers save money. A question that our customers always ask our technicians is, “Is cheap gas bad for my car?”

Don’t Fear Cheap Gas

You can stop worrying about using cheap gas. Many experts say it’s unlikely to hurt your car. More additives essentially afford more engine protection — but they also cost more.

Gasoline is expensive and you’re looking for every way possible to save money at the pump. You already shy away from premium fuel, knowing that your car doesn’t require it. You’d like to save a few pennies per gallon more by going to an off-brand gas station. But you can’t get rid of the nagging fear: Is the cheap gas going to damage your car’s engine? put this question to experts in several fields, including an automotive engineer at a major carmaker, gasoline manufacturers and two engineers with the American Automobile Association (AAA). It boils down to this: You can stop worrying about cheap gas. You’re unlikely to hurt your car by using it.

Because of the advances in engine technology, a car’s onboard computer is able to adjust for the inevitable variations in fuel, so most drivers won’t notice a drop off in performance between different brands of fuel, from the most additive-rich gas sold by the major brands to the bare-bones stuff at your corner quickie mart.

Still, spending a few extra pennies per gallon might provide peace of mind to someone who just purchased a new car and wants to keep it as long as possible. People with older cars might not be as concerned about their engine’s longevity. They can buy the less expensive gas and still be OK.

Steve Mazor, chief automotive engineer with the Automobile Club of Southern California, summed it up this way: “Buy the cheapest gas that is closest to you.”


Why is Tire Alignment Important?

alignment, auto tires, miami mechanic, little havana mechanic,At GM Auto Tech, in Little Havana, our certified mechanics understand how important it is to reduce gas consumption and tire wear, and prevent damage to other parts of the drive train. Learn more about correct tire and wheel alignment from the tips below.

Benefits of a Tire Alignment

Proper tire alignment helps the car travel more smoothly down the road with less steering correction. This reduces tire wear and improves gas mileage due to reduced friction against the road surface. Alignment also helps your car stop in a straighter line, reducing the stopping time and distance.

Symptoms of Alignment Problems

Your car’s steering will show possible alignment problems first. You will find it hard to keep the car traveling in a straight line. The steering wheel may also vibrate at high speed. The tires will show a noticeable slope on the tread, either inward or outward from the wheel well.

How to Correct Alignment Problems

If you see tire wear as described, take your vehicle in immediately for a wheel alignment. You will have to buy new tires, as the worn ones cannot be safely rotated to another position on the car. Alignment adjusts the wheels to travel at a precise 90-degree angle to a flat, level road surface, and exactly parallel to the long axis of the vehicle.

Our 4 Wheel Alignment system will help you keep your tires working properly and help save you money. Visit our mechanic shop in Miami, today for more information.

Oil Changes: How Often?

Do you really need to change your oil every 3 months/3000 miles?

miami, gm auto tech, miami, mechanic, little havana, oil changeAt GM Auto Tech, a Miami Auto Repair company, we tell our patrons that they should be proactive with regularly scheduled oil changes. Why? Well, regularly scheduled oil changes are one of the most basic and economic ways to maintain your automobile.

For years the accepted oil change interval (as per the carmakers) has been every 3 months or 3 thousand miles, whichever comes first. Why? Because the oils of yesterday degraded and broke down when left in the crankcase environment for longer than the prescribed interval. The combination of heat, friction, and the oil oxidizing over time resulted in an unholy clothing of the engine’s internal parts called sludge. As an automotive machinist for a good part of my career, I can tell you that sludge is an engine killer. Sludge takes a greasy, cake-like oily form and plugs oil return passages and acts like a sponge and soaks up good oil to grow its grotesque form starving the engine of vital lubricants. Once established, engine heat crystallizes it to a hardened rock of ughhhhhh, I have spent many an hour scraping and yes, sometimes chiseling established sludge from the inside of an engine before performing a machining operation on it! As the machinist prepares to perform a machine operation on a cylinder head, crankshaft, engine block or the likes he/she must clean their work meticulously before performing the prescribed operation. If the sludge is not cleaned properly, the result will be a failed engine.
