I had an oil change done at Meineke muffler. To my surprise it cost $71.00 and when I questioned the price, they said they used synthetic oil, despite knowing it took 7.5 quarts of 5w30 conventional oil. I complained so they took $10.00 off. Ironically, the next day "my service engine soon" light came on and has not gone off. Could this have anything to do with the synthetic oil in my engine and should I have it drained and the correct oil put in? Thank you.
I asked this question earlier today and I got a response in spam, but it would not open sorry.
