I am running into this problem with our 300CE... a quart at 8-900 miles...runs great, still.

i have the parts ...a little antsy about losing a valve... may or may not do it myself..

i use 20w-50 now..when i get them changed..it will still be 20w-50 dino maybe 15-50 synthetic if i can get it on sale.
