1990 Toyota Land Cruiser Question: hy-lube

Toyota as a manufacture do not recommend the use of any oil additives or modifiers. I have no experience with Hyper lube additives I would send them an email or look for recommendations on there website.
I see the additive on there web page that is a Zinc additive, this definitely should not be used in your Toyota as it damages catalytic converters. ZDDP was taken out of oils to maintain cat convt life.
