I drained the oil at 1500 miles and put the 50/50 rotella mix back in. The engine cranked like a full synthetic was installed. I have 6000 miles on it presently. I plan on continuing with this mixture. On another site A shell lube engineer stated that these two oils are completly compatible. He gave his name and phone number to boot. He said that a 50/50 mix of 5w40 sythetic and 15w 40 dino will give you a semi blend of 5w40.
I would say it's more like 10w40...
