After trying a variety of 5W20 & 5W30 oils in a '07 Kia Sedona 3.8L (rated for 5W20) I took a chance and am running an OCI with M1 0W20 AFE . The general consensus here is most any modern engine rated for 5W20 can run M1 0W20 AFE . Any way, 1,500 miles into the OCI the engine is quite , smooth and runs more "free" . Gas mileage is up about 0.05 ~ 1.0 MPG as well . At first I thought I was experiencing the placebo effect and a favorable butt dyno reading but the M1 0W20 AFE love continues . Lastly , no leaks or oil consumption to date ...I think I'll be running this oil again in the future . I am tempted to try the 0W20 QSUD (also at WM) but if the M1 0W20 AFE continues to be the best running oil I have tried - then I may not bother to experiment further .
