Some will say that you should wait 3 - 5K miles to let the engine seal up properly. However, I put syn in mine at about 100 miles.
Syn and E85 are fine. The oil system and the fuel system don't mix...if they do you've got bigger problems than deciding which oil to use.

If you run E85 more than %50 of the time the maintenance schedule says to change the oil every 3000 miles rather than 5000. However, running synthetic I only change the oil after assessing the oil condition...I look at it and if it looks real dirty I change it.

Ethanol is very harsh on engines and the oiling systems. Running E85 causes the oil to rapidy shear and drop the TBN and use up all the acid neutralizers in a very short time frame. Try talking to Paul or Jeff in the engineering dept at royal purple. They will also tell you to do oil sampling and judge how bad the fuel contamination rate is before going over 3,000 miles on E85.

This is from a manufacturer of E85 conversion kits.

Scroll down to Bold heading #5 ("Do I need to run special oil or change it more frequently?") and read the 1st paragraph.
