Ok I tried my first tank with about 10% wmo (filtered to 5 micron) and noticed a considerable increase in idle smoke and a little reduction in pump noise. Everything was ok no issues.

Tried my second batch at about 25% with no changes.

I filled it up this afternoon with a 50/50 batch and noticed within minutes a 200/300 rpm drop and a very noticeable change in tone under the hood. Definitely quieter running but seems to have intermittent rpm changes of maybe 50/100 rpm's.

Not sure how long its been since it had a fuel filter since I have only had the truck for about 3000 miles but I am planning on changing that 1st thing in the morning.

Anything I need to be watching for or expecting at this mixture?

Once again it has been filtered to 5 microns and the temp here today is about 55 degrees and has been similar thru the 3 tanks of fuel.

Thanks in advance!

I never had any problems with a 50 50 mix

I regularly run up to 90% in mine without any problems though I do filter to 2 microns.

^^what he said^^

Filter to 2 microns, 1 micron is better.

it might not be a bad idea to get a pressure gauge connected between the fuel filter & the injection pump. That way you can tell your having problems with the mix, clogged fuel filter or your fuel pump needs to be rebuilt.
