Ford F-150 2008 116 miles
My truck got an oil change, and they used thin oil, and the enging started vibrating really badly. I took it to the mechanic and he said I should use thicker oil, and they changed it. It worked somewhat alright. But after I drive 6 miles and make a stop, the engine starts vibrating badly again, and I have to leave it to cool down for 30 minutes. They told me to change the timing belt, but I did it and it still does the same
