So I went to a Take 5 to get my oil done (2,000 miles behind). Service man walks up and tells me that due to the engine ticking that he would have to turn me away due to liability. I agreed and understood but asked if he could check my oil level anyways. I explained to him that I experienced the ticking problem before and it turned out to be because of low oil. He agreed and told me if it was low that he could take me in and add a couple quarts if need be. Dude checks my dipstick, tells me I'm good on oil and recommended me to a "full service" shop.
Later that day I got ahold of a friend who agreed to help me change my oil. Turns out the car was barely holding all of 2 quarts. Changed it out and the ticking went away. Well my CEL is still on, should I take it to a shop and have them erase the code to see if it comes back? He also suggested I clean my valve cover due to the oil buildup.
