Changed to Mobil1 synthetic in Differential yesterday - drove 35 miles, no leaks this morning. So far so good. Previous oil was in good condition - yellowish and cloudy - can't say if that is real good, good or other, but nothing drained with it (metal). 117,848 miles prior to the change. Had considered Royal Purple but $40 vs. $20 for two bottles with no known advantage was a deterrent.
Today is Motor Oil, also Mobil1; considered Royal Purple but Mobil1 is readily available, recommended by Benz and going from Dino to Synthetic was a step-up as well. Tranny next month.
Likely could have stayed with natural but thought the added benefits of synthetic on cold starts (Chicago) would be beneficial.
