The oil light that is coming on, is it the change oil light or the oil pressure light?
its the oil level light, I think
What kind of oil are you using? sythenic or regular oil?
Is this the same oil you use everytime? and is it synthetic blend or full synthetic/
I don't know what the dealerships used. full synthetic for local meachanics
Okay,, so the last change was full synthetic? what was the weight? and the prevoius change before the problems started do we know weight and were both done at the same place?
I don't know, but I can ask .. both local facilities
Are you still there...
Okay, the oil level light coming on. Check and make sure the oil level is correct. We have seen the level sensors and pressure switches fail after changing the oil. Nothing was done wrong during the change it just happens. The puff of gray smoke is oil, the weight may be wrong, so we want to check this. Synthetic oils are great lubercants, the don't create leaks but can find the smallest sealing problems so weight is important.
We also want to make sure a synthetic blend was not being used previously, it was you will want to go back to the blend.
So are you saying go back to the dealership & both local mechanics: find out the type & wight of oil used. Then go back to the dealership type & weight?

Is it because what you start with, you have to continue to use (type & weight)
Synthetic oils don't sludge up like regular oils or blended oils. So the weight of the oil is important. It may come to a point that the valve guides or oil rings aren't going to seal completely and a synthetic oil is going to find that and without any repair you might have to change to a regular oil to help that sealing process. When you use a regular oil for any lenght of time in a vehicle you never what to switch to a synthetic oil.
