Oil light coming on

It comes on on ocassion..but the truck is full..could it be a sensor?

 

Yep could be oil pressure sender, or could be oil pressure problem. Is there any certain conditions it happens? See if you can find some common conditions it happens to duplicate it.

 

Oil warning light is related to pressure NOT level.
What/which oil filter do you use?
What's in it for oil?
What motor is in your truck?
How many miles ore on the truck?
Have you had a shop put a mechanical oil pressure guage on the motor and verify whether or not there is correct oil pressure?

 

Its a 2.4..lol..with 300.000 on it..it doesnt burn any oil at all..but it has a very small leak...so if its low the light would come on?...

 

the indication is only for pressure...although if you have no oil you won't have pressure. So you have oil but pressure is your problem is what your saying. Its exactly what GSRON said.
My buddy blew his engine up on his 93 prelude by always adding oil and never changing his oil filter. While he was driving on the high way his engine blew. his oil light was on for quite some time but its not that he had no oil. Just no pressure because his filter was clogged. CHECK IT OUT!!! lol

 

Well im going to change the oil and filter in it today..and see what happens..

 

Changing oil should not hurt anything, just pay close attention to the color of the oil, use a bright flashlight and look at the color, if you see a metallic looking color to the oil might indicate excessive wear. At 300k if all original you might have some wear issues developing causing oil pressure loss.

But I would look into the pressure sender, I have replaced lots of them on all different makes and models of cars for this very issue. Cheap insurance you could just replace the sender, I think they are cheap enough for you truck. Or you could verify what your actual oil pressure is. Best of luck Keep us posted!

 

I will man..the oil is kinda brownish gold and has been in about 2300 miles....i looked for metallic particles and didnt see any..doesnt mean they arent there...im gonna pick up sending unit also and change that before the oil change..i sure hope i can get some more miles out of it..

 

Yeah color sounds fine, I am talking about oil that drained out and it looks like metallic black paint. Your sounds fine. Try not to stress too much cars pick up the bad vibes Just kidding.

 

Does the light come on at idle when the engine is up to operating temperature? If so you might try a heavier weight oil.

A magnetic drain plug might be a good item for you to install in your truck. That way any steel bits would be attracted to it and it might help you determine the problem.

Another question from me is does the light come on going up a steep hill?

 

No it takes awhile to come on..say about 25 miles after start up...its just blinks and doesnt stay on all the time...changing the oil 2maro...

 

Try a heavier weight oil.

 

Well i changed the oil and filter and the sending unit...and so far so good..ive put about 70 miles on it and no light....thanks for all the help fellas.....i will keep you posted..

 

Not a problem! Glad to help out.

 

You could get a magnet and stir it around inside the used oil next time you change it out, that would give a better indication if there are metal shavings, better than eyeballing anyway.
