Meets requirements for API SN and ILSAC GF-5 Includes high levels of MOLYBDENUM (Moly) which reduces wear, especially at low temperatures where the anti wear agents are inactiveĪlways follow original equipment manufacture's fluid recommendations Provided superior protection in all temperatures " Formulated for use in Mazda automobiles especially those with SKYACTIV technology The back label on Genuine Mazda 0W-20 GF-5 with Moly Engine Oil says: " Molybdenum compounds, for example, not only provide frictional benefits, but also have been shown to decrease LSPI when used at high levels." MoS 2 is an inorganic compound composed of molybdenum and sulfur.Ĭhevron Oronite, who develops and markets additives that improve the performance of fuels and lubricants, has made the following comment from the link posted earlier:
Secondly, as piotrek91 pointed out, Mazda moly oil contains molybdenum which is different from "molybdenum disulfide", MoS 2. Knows his way around addpacks.Ĭlick to expand.Firstly, Castrol Syntec mentioned was US market only synthetic oil a while ago offered by Castrol, but it doesn't exist anymore and got replaced by different Castrol Edge synthetic oil which is available worldwide. Guy works in the lubricant industry and fills government contracts, etc. Take care Jon and always good to hear from you brother. No EP but still the best for the performance and longevity! The synthetic base oil is more highly stable at high temps and the additive packages are superior. Go with Castrol Syntec as I have recommended it for years but one step up is Amsoil. That's such a huge falsity but sells donuts, if you know what I mean bro. It was originally designed as a dry film lubricant but like graphite, some "know it all" genius (NOT) decided it would be a good addition to oils. Hardly any difference between the Castro Syntec and Mobil 1, but the Mazda has way too much MoS2 (moly disulfide) which will break down under heat and pressure and become Mo2S3 (moly trisulfide) which is abrasive and causes abrasive wear. I know I REFUSE to use moly in a gun oil. Some of the additives (especially Moly) are off the scale compared to these other oils. A high Viscosity Index indicates less viscosity change when temperature increases, indicating better resistance to thinning, for a given oil and, likely better film strength retention under heat duress. Viscosity Index (VI) is an arbitrary scalar value that indicates the change in an oil’s viscosity withĬhanges in its temperature. Kinematic Viscosity at 40 degrees C (cSt) 35.0 Kinematic Viscosity at 100 degrees C (cSt) 8.3 Mazda's new oil is light but has a very impressive VI:Ĭompare this to the recommended high moly Mazda 0W-20: Source - Bobistheoilguy Oil Analysis postings. I'm up to 40,000 miles with no issues at all, always used Mazda filter and moly oil. Temperature for Viscosity of 150,000 cP Min.

The moly content is off the charts compared to other oils. TABLE 2 SAE J306 Viscosity Grades for Axle and Manual Transmission Lubricants (2) SAE Viscosity Grade Max. Agreed, some may argue it's a waste on money, but I'm going to stick with OEM moly oil that came with the CX-5.
