Its going to be:
AmazonBasics Euro 5W40
AmazonBasics HDEO 5W40 or Mag1 version or Supertech
Castrol 5W40
Valvoline 5W40 Euro
Once thats done my experimentation will be complete on the Walmart/Amazon sourced 5W40s.
IMHO 5W40 is great for severe service like towing or taxi style work or for those turbo Subaru guys....
How exactly did you test the oil? What parameters of the oils aren't adequately represented by the approvals or certifications and the grade designation?
