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.

 

i run e85 all the time.
my oil looks normal.

 

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?

 

Good possibility
