Mikie,
I'd add 5 qts of oil and the bottle of AutoRX ...it will provide more effective cleaning at a slightly stronger concentration.
Don't add AutoRX to the Amsoil - they already use certain types of organic esters in their basestock blend and I don't think it will do much of
anything ....They will not warranty the product if you start doctoring it with additives.
