Oil color E85

This is my 2nd oil change since switching to E85 and I noticed it's a reddish brown color. Is this normal? I wasn't really paying attention last time so I have no comparison. Car runs fine, but the oil color threw me off. I use Amsoil Z-Rod 10W30 and change every 3k. I'm thinking about getting an oil analysis. Any thoughts? Thanks

BTW I run E85 full time, I haven't put 91 in my tank since January.

You have any pics? Sounds like used oil color when your looking at the stream out of the drain as it gets smaller.

When I used to run E-85 full time my oil did not turn black like it did when I ran straight 91. Since I ran 10W-30 Mobil 1 it would maintain a straw color on E-85. I would change around ~ every 3 - 4 K.

Does Z-Rod normally have a red tint to it?

whtrice it's normally an amber color. I'll get some pictures of it.


This just occurred to me, the motor had a few thousand miles on it before going full E85 ( new motor ) and I used Amsoil break in oil which is red. Do you think it's still getting cleaned out?
