My 2007 3.8L V 6 Kia Sedona is now out of warranty . Previously I was running PP 5W20 from WM but looking to try something else since the PP change to Pure Plus technology . I'm not too keen on Castrol or regular M1 5W20 / 5W30 and undecided on QSUD 5W20 / 5W30 ... The M1 AFE 0W20 & 0W30 get good reviews yet as most know Hyundai / Kia only spec 5W20 as preferred and 5W30 as acceptable ... What specifically would POTENTIALLY happen using M1 AFE 0W oil in that engine ? Also if you were to use a M1 AFE 0W oil in that engine - would you use a 0W20 or 0W30 (engine has 109K miles now on it) ? Thanks in advance ...WM has PLENTY of M1 AFE 0W20 / 0W30 on the shelf and I want to give it an honest look !
