Mazda "Moly" oil revisited
Hi all. Apologies if this has already been mentioned, but having just completed another "Mazda moly" oil change yesterday on my 2014 Mazda 6 bought new in late March 2013, I was surfing on-line and noticed that Idemitsu (the maker of this "OEM" branded oil) now markets this same oil under a new name (Idemitsu Zepro 0W-20 with Advanced Molybdenum - their spelling BTW). They also put out a press release that all their "once OEM oil" is more easily available and now available for purchase on Amazon. I checked it out and sure enough, there they were on Amazon (5 variants). The Moly variant was just shy of $30 for a 5 quart jug. I ordered a couple since I plan on continuing to use it.
Just a "heads up" for those of you that use this oil (being a constant reader of this great forum I know there are some fans out there that swear by this stuff). I've been using it since day one along with the Mazda factory oil filters (which is unlike me, normally I just buy local but the internet can be a wonderful place)! Never had an issue. I average 30 MPG in maybe 65/35 city to highway driving over the 5 years I've had the car (Minnesota, so numbers change some with the seasons up here).
Another heads up that I believe I HAVE seen mentioned here is that the Mazda OEM oil filter spec'ed for this car has changed part numbers and suppliers recently, the filter is now sourced from a Thailand supplier and not Japan. I have both versions of this Mazda branded filter along with a few Wix 57002's (which was designed specifically for Skyactiv) and compared them all side-by-side (did not cut into them however). Generally speaking, I'd say the Japan made one (Toyo-Roki PE01-14-302) is definitely heavier and feels better constructed (but appears to be no longer available), with the Thailand one (1WPE-14-302) and the Wix lighter but similar in shape/size/appearance. The Thailand variant still comes with shrink wrap on the open end like the Japan one did too. I'm sure any variant of these three are fine, but these are the only one's I will use personally. The Mazda oil filter "cap" wrench I bought for the Japan sourced one appears like it will work with all three variants, as well.
