There's also "high mileage" oils, in 10W-30, that are probably a good idea. They contain more zinc than other oils, and some contain seal softeners (like stool softeners for old cars :-) Costs a bit more than the cheapest crap oil, but probably worth it. Oil's not a thing to cheap out on. If you can spare a few hundred $$, and are somewhat handy, you can really revive a motor with a valve job, if the rings are any good. If compression is OK and reasonably even you can liven it up and get another 50K miles or more. On an AMC six it's not a hard job. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
