Hey guys - I bought nine 5 qt jugs of MC synblend 5w20 a couple years ago really cheap. They have an API rating of SL and all are sealed. Is there any reason why I shouldn't run this in my wifes 08 Pilot with a Purolater PureOne filer ? The Pilot just turned 21k miles on it and I plan on running 5k on each OC or 20/30% on the OLM. Let me know your thoughts ?
