I was driving home from work using my Buick Apollo when suddenly, without warning, the "Check Engine" light went on. What does this mean?

The "Check Engine" signal can be a frustrating circumstance to encounter. It leaves many confused as to what could possibly be wrong with the engine. But here are the most common causes that trigger the light to pop on. First is that the problem may lie in the oxygen sensor. When the oxygen sensor becomes faulty and/or grimy, it would send the wrong signals leading to a decrease in fuel mileage. Another common cause is a loose or broken fuel cap. Yes, this may seem like a minor problem, but it can send the whole fuel system into disarray. The ‘Check Engine' signal is also usually caused by a malfunctioning catalytic converter. The catalytic converter is in charge of converting carbon monoxide into safer compounds. It works together with the spark plugs and the oxygen sensor. When something goes wrong with it, you have to check these other parts as well. Lastly, a faulty Mass Air Flow Sensor may be causing the light to go on. The Mass Air Flow Sensor malfunctions due to an improperly installed air filter. Also, this may also be caused by the air filter being dirty and needing to be replaced.

What are the pros and cons of using synthetic oil for my Buick Apollo?

This would depend on your Apollo's age and mileage. Generally, older cars with higher mileage may not be suitable for full synthetic oil consumption. Perhaps you can try an additive or the semi-synthetic ones. Check your owner's manual, if you have any, or consult the local dealer or local technician regarding this. An advantage of using synthetic oil is that since it is more slippery, the engine becomes better lubricated. This can enhance your engine's longevity and can help prevent metal parts to become worn out. This can also boost fuel economy by 2 to 3 percent. The downside is that synthetic oil is definitely more costly than regular crude oil. However, it is able to last longer.

Saw our old Buick Apollo sitting in the backyard; it's just sitting there and would not start anymore. The last time it was used was more than a decade ago. I want to revive the Apollo again with one of my buddies. What are the first steps in making the Apollo start again?

Reviving an old car may seem like an exciting and fun thing to do. However, its success depends on the car's condition and the extent of damage present. First, make sure that your car is not sitting in soil and dirt. Bring the vehicle inside a dry, cool place such as a concrete garage. This will make it easier to clean all of the dirt and mud. Wash the gas tanks and replenish with a fresh supply of fuel. Change all the fluids as well. That includes the brake fluid, the power steering fluid, the transmission fluid, and the antifreeze. To get an old car running again, or at least being able to start, these are the common parts you should consider replacing: the thermostat, water hoses, alternator, brakes, exhaust, cables, and the lights. Get a brand new battery as well.
