Posted by "TQ" in reference to the claims that the Spectro GL5 can do damage to yellow metals in Harley transmissions.
I wrote to Spectro asking them the exact same question as that asked on the Mobil site. Here is their response:
Our Platinum synthetic gear oils are GL-5, however the additive contains a component which mitigates against the yellow metal corrosion you mention. John
