Solution #1 has a good general approach. He didn't quite explain that when you go to an Autozone or affiliated type car parts supplier they will read the fault code from the car's computer using a "scan tool." They do this so that they can sell you the part. But, some parts are not easy to replace, and you should be very comfortable working on machinery before attempting a repair. I've done every type of car repair for myself for 50 years, and I don't always choose to do a repair myself just because I can. Consider going to the dealer right away as the check engine light comes on the majority of the time for one of two reasons: 1) it is getting an emission system fault often due to something as simple as a loose gas cap in which case you should check your manual to see how long/ or many on/off cycles it will take to clear the code after you retighten it :-), 2) an Oxygen sensor fault that may be covered by the warranty. When an Oxygen sensor fails the computer will go into a default mode that usually causes the car to consume more gas, but will not hurt the engine. Usually these sensors will last at least 100,000 miles or more with the generally clean fuels available today, but my wife's '06 Sonata lost one at 27 k Mi. Fixed under warranty, but took 4 days to get one into stock! Hyundai dealers tend to carry very meager parts inventory even for commonly needed items like fuel filters.

The engine lite comes on due to an input sensor to your cars computer going out of its parameters. it will come on for a hundred or so different reasons. if it is on solid, it is considered safe to drive. it needs to be diagnosed by retrieving a code from the computer. if youre mechanical inclined, go to autozone and get the code read and i/we'll try to help out further. otherwise you will want to see your service shop for repar.

I have a 1996 Dodge Stratus ES 4 door Sedan. It is a 2.4. I had my oil changed in June of 2014. How long does an oil change last and when is it advisable to get it changed again? Thanks

oil change period is every 6 months or 5000 miles or 10000klms
however as the oil collects moisture from incomplete combustion any short runs that do not allow the engine to come to full operating temperature to boil off the moisture will need a more regular oil change
So if the car does runs of at least 1/2 hour the the 6 months will be ok
On the other hand if it is only used to go around the corner to a corner shop then more frequent oil changes will be required
Good policy is oil filter with the oil every 6 months or if more frequent with every second oil change

White smoke out of the exhaust means a coolant leak in the engine. When you accellerate hard and get that it could be the head gasket is leaking. The bad thing is that coolant leaks can ruin the catalytic converter too. You are looking at several thousand in repair bills.

Took my car an 08 Hyundai Sonata for an oil change to the dealer and they told us there was sludge in the engine we have been keeping up with oil changes ,is there a defect with the sonata's engin

There are two main causes for sludge, not changing the oil and filter at regular times, and not running the engine long enough to get it hot.
You might want to get a second opinion from a shop other than the dealer. The dealer may have a sales promotion on engine flushes this month.

Oil change intervals

I personally hold synthetic oil as the high-standard of lubricants. However quality varies. Without completely flushing I would not recommend use in a high mile engine.
"ordinary oils" are far better than they used to be, but begin to break down substantially after about 2500 miles. No dealer wants your car to last beyond the warranty period. They sell new cars! Changing your oil & filter at 3000 miles is reasonable, and not too often. If you are using quite a bit of oil, take care of all external leaks you can. It will help a lot. You can't extend change intervals because of oil consumption. The filter must be serviced regularly or you will cause more internal wear.
