Secolube 500 question

Not to mention the cost savings. Buying Rarus 827 for a Yong Heng is like buying 127 octane gasoline for a go kart. Overkill, overpriced, unnecessary, and uneconomical. Secolube 500 is not only a good choice for a Yong Heng but for most dive quality compressors. The Yong Heng manuals went from recommending #46 hydraulic fluid to Rarus 827. One extremely cheap, smelly improper useage fluid to an extremely expensive, smelly lubricant made for precision applications far beyond the requirements of a Yong Heng.
