You can buy Indemitsu 0-20 oil from AutohausAz gallon for about $18. Not a bad price for all of us with a 0-20 oil need for Subaru, Honda etc. Have no specs on what this oil is vs knowing what the Mazda specs are. Either way price is good. They ship for free orders over $50. 3 gallons would give me 2 oil changes with my Subaru Forester 2012. Beats the heck out of $81 for a oc at the stealer and most important I know it was done right!!
