the ScanGauge doesn't say what the codes are, only that the DTC count =3 at this point. I have ordered the AutoEnginuity but it hasn't arrived yet.

I did try Autozone and O'Reilly and their scanners both said no codes.

The last week or so I'd been having an increasing amount of blue/white smoke on start. It got to where it would take warming all the way over 190 before it would stop smoking, and sitting for a while even then on warm start it would smoke. But, it was intermittent. It DID stop smoking.

I changed my oil and oil & fuel filters Sunday. It smoked a bit Sunday and Monday, less than before, and there was none today. It's also been significantly warmer overnight than last week though, so there could be more things going on.

This is my second T6 oil change, I use Racor filters from DFO. 5,000 miles on the last three oil changes.

I also switched to the white bottle Diesel Fuel Supplement for this tank.
