service/maintenance
Now that I have secured a blend door actuator for my '89 and have some additional maintenance scheduled with the actuator install. I am torn between synthetic, synthetic blend and conventional 5-30. Been running Mobil 5000-5/30. About to the 160,00 mile mark and no oil leaks. Also, having the rear end fluid changed and had planned on Valvoline 90-140 with a limited slip additive separate . Does this sound right? Also, after the rear fluid change, is it necessary to drive the car in circles to distribute the new fluid? Open for opinions and advice.
thanks
Jim
