Greetings, this is my first post in this forum, I have a concern and a couple of questions, I tell you, I have a 2007 Hyundai Sonata 3.3l V6 engine, with 120k miles, I have noticed that when starting the vehicle in the morning, or after After driving it for a period of time, the oil light takes 2 to 3 seconds to disappear after the engine starts, I would like to know if it is normal for that model of Sonatas? On the other hand, I have read that perhaps the oil filter which goes in the upper part is emptying very quickly, I recently changed the oil 5w 20, and I used the original filter that Hyundai sells, the other question is, this model Does the vehicle have an anti-drainage valve near the oil filter? The car feels excellent and without any noise out of the ordinary. I have read that these cars have a noise that is "common and normal" when starting it cold and the cause is the position of the oil filter or its brand.
Oil light keep on 2-3 seconds after startup

It is difficult to diagnose any potential problems. Here are a couple of guesses.
Is your oil level to full? Correct oil?
Are you losing oil between oil changes?
If you are losing oil then worn piston rings are a possibility, as is a failed head gasket. This could also show up with lost coolant or oil mixing with the coolant to produce a milky colored fluid.
You can pull a spark plug and see if it is carboned up and oily, which would indicate worn rings.
The oil pump could be weak, also. Don't know if the oil pump on the 3.3 is accessory belt driven, but you can easily check the belt for tightness.
Could also be a bad oil sending unit.
Might be worth a visit to a good independent mechanic. Check out the consumer reviews online and use a good one. Considering the age of the car, if it is running well and keeping its oil you might keep driving it and keep an eye on any oil loss. Hard choice.
I'd double check your filter. If it is Hyundai OEM and correct for your car, that shouldn't be a problem.
Good luck.

The car does not lose oil, it is always at its point, even when it is my turn to change the oil, it is full, there is no loss of power or smoke coming out of the exhaust or the oil dipstick, I have seen videos of some Sonatas that when turned on do what Same, it takes a couple of seconds for the oil light to go off after the engine is running. there is no milky substance in the coolant or oil.

If there are no unusual engine noises then all seems well.
Except the psychological component. I had a 1963 Dodge Dart where the engine light remained on for several seconds. Drove me crazy looking at it every morning.
May be worth an hour of time by a good mechanic to confirm all is well.

Yes, the psychological factor is what leads you to ask these questions, but the truth is that the car has no faults, just that delay in the oil light that takes two or three seconds to disappear after starting the car, however in that period of time there is no strange noise.

I see this thread is several months old, but your questions sparks a memory. I had a buddy with a similar car and oil pressure issues. The way I recall, someone had replaced the oil filter and thrown away that cage that sits inside the filter, with the small o-ring on the end of it. This thought is worth about what you paid for it, but something to consider. Did the problem start suddenly or has it been this way all along?
