Oil Change 180,000 MILE 1994 Mustang GT AODE
Hey everyone my car has 180,000 miles on my 1994 GT. I have been using 10W30 fully synthetic Mobil 1 Extended life motor oil. I dont think its working that great. I hear more clicking in my valve covers. Should i move up to 10W40 OIL? Whats the difference or should i get like 15W50 or is that to much. I run my car hard at times.
