Don't use unleaded unless you know for sure that it is the slightly later 18rg with the updated heads (with the hardened valve seats. I am also running an 18RG, it is the earliest 18rg, withthe toyota head, so i use LRP, if you aren't sure of whether yours can use premium unleaded, then take it to a mechanic who works with the old toyota twin cams, he should be able to tell you.
