I posted on the forum in a different discussion a problem I am having with my truck. Last Thursday I got my oil changed at the local Ford dealership. they had asked me if I wanted the regualr oil or ful synthetic oil. I choose the cheaper regular change. I suspect it wasn't "full synthetic". Well a few days later I am having P0022 issues. I have changed my cam sensors and the truck runs a little smoother but still wants to stall sometimes. I am wondering if putting the wrong oil is affecting my VCT selonoid and causing it to throw a P0022 code? Just thinking out loud guys.... PLEASE HELP!

 

no, regular oil isn't gonna have anything to do with your truck running different.

 

Even if they put 5w40 by accident?

 

oh, well, you didn't mention that. That might have a chance of messing with the sensor, but if its summer and you change it out for the correct 5-20 it shouldn't do any permanent damage. I've always had 5-30 in mine up to this point and everything is good. sure 5-40 is a lil thicker but not a whole lot.

 

I pretty sure a Ford dealership knows what oil to put into your truck.
