What about blinker fluid? And how often do I need to rotate my muffler? I think it may need new bearings.
Speaking of blinker fluid. I remember when i was little and was living back in russia lots of car had liquid in the headlights. Russian auto makers could not make headlights that were sealed well so they put liquid in there so when the lights get foggy the liquid mashes the foggyness away when you take turns and go over bumps.
CRANKCASE---I use Royal Purple with a Purolator Pure 1 oil filter. True, I started it with a fresh motor that didn't burn anything, but I believe the majority of people who care use Mobil 1 or some other high-end synthetic, and change it every 2-5k, depending on conditions. Winter I change more often because of the longer time spent warming the car up. TRANSMISSION---Scotty's coctail. Search this one. Great stuff. DIFF---75w90 or 80w90 non-synthetic, I added limited slip additive because it was easily available. Plus I change mine often. 15-30k; again, depending on conditions. Anything else in specific?
