    Hello I recently purchased and installed the new add w1 version 3 which has two inlets and a single outlet for my 2013 Kia Optima SXL with the 2.0 turbo. Morning after the install I had a check engine light pop which came back with codes “P0106 + P0605”. I understand I do not have the correct...
  4. Engine and Technical Discussion
    I took my 2013 Kia Optima in for the engine recall test to determine if the rod bearings have been damaged by manufacturing debris. They changed the dipstick from yellow to an orange one and filled the engine with 5.2 quarts instead of the 4.86 quarts in my owners manual. They did not know...

    Hello everyone, new Optima owner here. Bought the car at 44 miles in December and currently have 7500 miles on it.

    Hey guys, A couple of days ago my oil light flickered on an "on ramp" for the highway, which prompted me to check the oil and I found that the oil in the car was well below the "L" line. I last changed the oil in Dec/18 and use synthetic oil 5W-20 probably only having driven the car about 4/5k...
  11. 4th Generation Optima (2016 - 2020)
    Hey gang, haven't posted in a while since it's my wife's car. I bought it new for her, and it only has 16,900 miles in 2 years. I don't remember it using oil initially, but now it's burning about 1/2 the difference from min to max on the dipstick (about 1/2-qt???) every 2K miles. I know it's...

    Just had the oil changed on my car and when I can home I checked the level ( after letting it sit for 10 mins) and the level seems to be above the "F". Is this a concern?

    What's going on everyone, my Optima is ready for its first oil change and I'm curious what type of oil to use, we're entering the winter months here in Ohio so I was curious what weight of oil to use and do you use different weight oils for the winter and summer months? I tried searching this...

    My '12 Optima SX turbo oil feed line started leaking under the foil where the flex portion is. Hard to tell where it's coming from as the entire bottom of the passenger engine bay is covered in oil, but pretty sure that's what it is as squeezing the foil portion yields oil. It's leaking right on...

    I'm at 93k and replaced the spark plugs today on my 2.4L EX. I examined the boots and noted that each one of them have a ring of oil about half way up the boot (see below pics); I was expecting them to come out clean so I was curious if this was normal? I assume it's normal because each boot had...
