I think Mobil 1 is the most popular synthetic, but I would like to switch to Amsoil b/c I've heard so many good things about, but I don't want have to order it and pay s/h charges every time I need it changed. So I'm thinking Royal Purple since they sell it at Wal-Mart. What would you suggest?

I have so been neglecting my car and I need to be reported to CPS! No oil changes for the last 20,000+ miles! When I change the oil I'm going to have a used oil analysis done with Blackstone Labs. The car currently has 117,000 miles and hasn't really been driven for 2 years b/c I need a Ca approved catalytic converter(P0430 error code). I've been driving my 92 ES 300 all this time, but I'm now in the mood to getting my Is back on track. I bought some Mobil Clean 5000, but I'm thinking maybe I should have got mobil 1? I also got Denso OEM iridium spark plugs and oil filter.
