no more than my wife drive her truck,im thinking that i am getting a build up of some sort,on a sensor.
this sensor is the one that apparently reads the oil some how some way,im not sure.
but i change the oil in her truck pretty religiously,way before the 3k mark.
just because my truck sees 3k WAY before hers,and when i buy the oil i just buy it by the case (5w30 valvoline)and i figure what the hell just change hers anyways,no big deal,(clean oil cant hurt anything)
so the oil has always been real good and clean.
but i cant ever get the change oil to reset and it is always telling me to change the oil.
i am assuming that the ecm calculates how many starts and stops keys on and key offs etc. then tells you when to change the oil.
but the last road trip i took the change oil light did not come on,due to the fact (i think) because the truck really got heated up and ran for 6hrs non stop on the highway.
so my theory,is that the motor internally needs some sort cleaning.

 

need alittle more info on said vehicle, to give you a good answer!

 

It sounds like she drives it harder then you do. The computer calculates many factors on when you should change the oil.

Like said above more information on the truck would be great also.

 

So have you reset the change oil light? turn key on and floor the gas peddle 3 times and the light should be blinking and turn the key off.

 

^^ I bet $1 that's it

 

yes,i have gone thorough all the procedures to reset it, but every time i change the oil,but it doesnt ever reset..
the last road trip i took,i didnt change the oil(because i knew it was still good) but i changed it when i got back, i then reset it,and it reset for the firs time sense i have owned the truck,and it never came on till way later as expected.
i called the dealership (friend works in svc dept) and we went through all the damn steps on resetting the light etc.....
i have owned and changed oil in more than 1 LS based vehicle.
her truck is a 2002 2500hd 6.0 4l80 4.10 trailer tow pack extcab pewter in color.
you have lost a $1 homey!
i try to reset the hell out of it but it will not reset for some reason,i turn the key on and step on the pedal 3 times and it will not reset.
it has reset 1 time by following the standard resetting procedures.
but i had taken a road trip and when i got back it was due the oil change(i keep a mileage chart for my out of town work).
it then let me reset,but sense the road trip,i have had the light come on and tell me to change the oil shortly after,but the truck was not even close to a oil change.
my truck was due so i changed my wifes oil at the same time as i did mine,i reset my truck, but hers will not allow me to reset.

 

Nothing should be wrong with the oil then. Its just not resetting. Do you have any floor mattes or anything that could possibly blocking the peddle from going all the way down? I dont know how much the TPS has to read for it to reset, maybe get a scan tool and make sure the computer is reading 98%-100% from the TPS sensor, just an idea.. You didnt mention how you reset it but theres people out there that just think the computer knows you put fresh oil in and resets.

 

see, i won $1....though no fault of yours, it isn't resetting. PM me for my PayPal address

 

i try to reset the hell out of it but it will not reset for some reason,i turn the key on and step on the pedal 3 times and it will not reset.

 

iirc it has to see 0-100 TPS% 3times within 5seconds, sure your doing it fast enough? if so i would maybe investigate into why its not seeing that like mentioned before..
