I recently had my oil & filter changed. Less than 2000 miles later, the engine began running slightly rough and shifting was erratic. I took my car to the dealer and, after computer diagnostic, the service rep informed me the onboard computer said the oil change business had put in the wrong oil. Because I didn't have any paper work on me, I paid $353 to have the engine drained and flushed and refilled.
When I returned home, I checked the service invoice and found the oil used at the previous oil change was 5W-20, exactly as specified in my owner's manual, the same type I've always used.
How does the computer measure oil viscosity during engine operation? Does this part fail frequently? No one I have talked to has ever heard of an "oil viscosity sensor, " but I get lots of chuckles when I ask.
have the same problem?
