- 2014 Mazda CX-5 GT AWD w/Tech
I had used the Mazda Moly oil in my CX-5 from new until I learned on here that the Idemitsu Zepro Eco Medalist was actually the exact same oil. I started using that instead because it was available in a 5 quart jug for around the same price (and sometimes less) that the Mazda branded individual quarts and one jug is more convenient that 5 individual bottles. I changed my oil yesterday which got me thinking about oil. I recently read that there is a new specification out for motor oils: SP/GF-6 which supersedes SN/GF-5. Since the Zepro is SN/GF-5, I wondered if there would be an upgraded version coming out. I went to the Idemitsu web site and saw all of their products. Their regular oils were all showing the new SP/GF-6 versions, but the Zepro was still showing the current SN/GF-5 version. So I reached out via email to Idemitsu and got an answer right away. There are no plans to upgrade the Zepro to SP/GF-6 and in fact, they are discontinuing the whole Zepro line. So, if you like that oil with the extra moly you should probably get some while it's still available. I know I'll be ordering some more right away.
