I never just reset any message light. You sure they actually changed the oil at all? Maybe they just reset the message, thinking you wouldn't look at the stick.....Check and see if the oil is dirty. The sensor might actually be working and letting you know it is dirty.
Ya never know these days.... I always change my own oil and always put a date/mileage on the filter. I always tear off the oil filter box top and write the mileage and date on that and throw it into the glove box as a reminder too.

Ok there is no sensor for oil, at least not directly. The vehicle infers engine oil condition by using an algorithm that tracks total engine run time, engine starts, ambient temperatures, engine loads, vehicle distance traveled and probably 78 other factors. It is like if you are making a delicate baked dish that will collapse if you open the oven too soon so you cannot observe it directly, you take into account oven temperature size of dish and time and if you have a good enough algorithm you get perfectly cooked food.
Again no sensor.
Also it is not about the oil being dirty, it is about the additives breaking down and viscocity changing due to long hydrocarbon chains being chopped up by your motor and heat into short chains...
I've noticed their oil change guy is kind of incompetent. They couldn't even find the location of the oil filter for the truck that went in before me. (don't know the year , but sure is a 4th gen) When they do the oil change for my truck , the guy dropped a plug on the ground and couldn't find it. When the other guy add the oil to the engine, I asked is this 5w20 , first he hesitated a bit , then say yes .
All of this above, make me have a weird thought regarding to this engine light thing. what happen if he didn't put 5w20 to my truck ? will this be possible ? does Chrysler use 5w20 for all the model they made ? I mean will the dealership use 1 grade to fit all ? or that depends on different car comes in and they will check the spec then add different grade of oil ( which they didn't do it obviously) .
Last, can anyone tell me what if my weird guess is right, what's the damage to my truck ? or how can i find out if the engine oil in my truck is 5w20 or not ? I never do oil change my self , does anybody know what is that plug for ? I thought only thing they need to replace is the oil filter, is that a plug for the front differential ??why they need to unplug that ??
Many thanks!

As to suspecting your oil is the wrong weight... well there you do have a problem. Next time bring your own oil. As for now, you might have MDS malfunction in the short term or break in the longer term. If you really are that worried, rechange your oil and have all work done at the dealership that way they have it documented when your engine blows.

LMAO... dude, I needed that.

Plug was probably the oil drain plug... it is how you get the old oil out of the motor. I used to drop mine every time I changed the oil.
