A few more Questions

[john manning <jlm10@freewwweb.com>]

Thanks to everyone who answered my question about tire jacks. With such
a knowledgeable group I thought I'd ask afew more. With the TR-4 engine
what grade of oil is best ( I live in SW Pa. ). Also do I need to add an
additive if I use 92 octane? Are the bolts withworth or metric or...? I
bought a heavy black rubber mallet to knock off the knock off's. Is this
best. Can I find a manual somewhere? Thanks for now, John
