I have a relative’s vehicle that calls for 0W20 oil - a quick online look at Walmart it would appear M1 0W20 ESP is the best available 0W20 synthetic oil option at Walmart for best base stock , approvals , wear control , keeping an engine clean , full OCI protection or any other yardstick of measure you want to throw at it for a 5K - 7K mile OCI … Do you agree or do you beleve there is a better made 0W20 synthetic off the shelf oil at Walmart that you prefer for typical , less than 10K mile OCI’s ?
