switched to T-6
Just switched to Rotella T-6 5w40, truck loves it. Its been a lot cooler here the last week and it starts right up like a champ in the morning, but I did notice a little white smoke.. very little and it clears up within a few seconds. You can barley even see it. Is this normal? FICM at 48 on start and back up to 48.5 while driving.
Seems like my EOT and ECT are always 15* apart until the truck is fully warm, is this normal, even creeps over 15* but only durring warm up. ECT is always higher.
When the truck sits all night 12+ hours the numbers are always the same or off by 1 or 2 between EOT, ECT, and TFT.

Depending on weather but there is often condensation in the exhaust. Ever notice a car with water slobbering out of the tailpipe at a traffic light?
As daddykitty said above, temp spread isn't a concern until your truck is fully up to operating temp. Check it like this:
TSB 09-8-3

Yeah I should have mentioned its almost like condensation, nothing like a car on a cold day. Just had the radiator flushed too and no leaks or coolant loss. Degas cap looks good too. Next project is to replace the heater core.

My truck seemed to like the Rotella T6 also. Smoothed it out a lot in the mornings. In my case the FICM is good, the ICP/IPR is good and RevX helped a lot with idle quality on cold starts so I'm sure it's stiction. I may try cleaning my spool valves on the injectors this fall before the temps start dropping. But for now the Rotella seems to be working noticeably better than the Motorcraft Dino I was using before.

I'm not sure if they turned it on or not. It's not his first rodeo but I wasnt't here either lol.
The heater works fine, but I have that sweet coolant smell in the cab, and have had that for a while now. Before I did the flush.

Sounds like your good to go. Just keep an eye on the deltas after the engine is totally heat soaked. Usually about 20 miles at highway speeds. Could be longer with colder ambients.

This says the coolant runs 15 degrees warmer, is this correct or a misprint?

While the truck is warming up, coolant will heat up faster than the oil. The difference between ECT and EOT only matters once you're up to operating temperature of ECT>=190*. So any difference, 15* or greater, where the ECT is GREATER than oil temp while LESS than 190* doesn't matter. If you're seeing ECT never get to 190* but EOT climbing up to 190*+, it's probably a thermostat issue.
