2016 Optima EX
The saga continues..car was serviced in December oil light had been flickering intermittently, i took it in and they marked the dipstick to start a 500 mile oil consumption test. I bought it back after putting the miles on the car and they said that Kia settled the motor dispute and the dealers "advice" was to keep a quart of oil with me at all times. I started checking the oil after an additional 1000 miles and then after an additional 1300 miles. Both times the oil was a quart or more low. Has anyone else experienced this? Should i add an oil treatment Lucas, etc?
