Why does my oil light come on in my 2003 dodge durango even after getting tune up and oil changed?

Greetings:

What engine does your Durango have? Your tune up interval for spark plugs is every 30K. When was the last time that was done?

The 2003 was the last year of the Generation 1 Durango, and is considered the best of the 98-03 years.

Low on oil or bad conection at sending unit. Maybe even a bad sending unit. Make sure the engine is off when checking oil.Not trying to be rude.

Did you change the oil yourself, or was it at one of those quick lube places. If you had it done by someone else, you really don't know what they put in your engine. Their oil is bought in bulk, by the barrel, and it's the cheapest stuff in the world. Some of it is even recycled oil. If I were you, I would change the oil again, using premium oil from an auto parts store. Some of those lube places even clean up the old filters and reuse them. 5w30 is the correct oil viscosity. I would go for the full synthetic oil. It lubes better and lasts longer.

it may be consumeing it pull a spark plug and see if it is oily fowled or very white it may be using oil do to bad rings

4 and a half to 5

tune up time change plugs wires pour injector cleaner into gas tank change fuel filter

sounds fuel or fire related.you can go to autozone and they can diag it for free.if you havent had a tune up in a while you can try to replace spark plugs,plug wires,fuel filter,air filter, oil change ect.

It might be faulty oil pressure sensor or bad oil pump, but might be adressed to recent oil change. Sometimes oil get viscouse in winter and cause oil light to come on. For winter the recommended one is 5W-30
Oil light should come on for less then a second during starting the car. If it comes longer or when you push the brake it might be the sign of bad oil (sometimes), faulty oil pressure sensor (mosty), bad oil pump (often) or internal engine problem (very rare).
Good Luck

Replace the Plugs, Plug Wires, Air Filter, PCV Valve, Change the oil and Filter, Grease the Fittings on the Front end and if there are any in other Locations. That is the Basic Tune up Procedure. Please Rate My Response! Thanks!
