Peeps running e85 query about stronger blending over time.
Hi all,
I am about to switch to e85 blend to give the engine a bit more headroom with the corky turbo. I just had one scientific question in mind. I could be completely wrong with this, but hey it seemed like a good discussion.
Say I fill up the first time before my tune with lets say at 1/4 of a tank of P98 left....15L of e85 and completely fill the tank to the click with P98. I go for my tune on this mix, all is well. Less knock, more kw.
The next time I fill up again at the 1/4 mark, hell why not, let's fill again with 15L of e85 and completely fill with P98 (45L all up, including 1/4 already in there). However, this time my tank was not straight P98 as it was before the tune. It is now a blend of e85 and P98 in (0.25 : 0.75) ratio.
My levels of e85 are now higher and continually get higher over time if I fill from 1/4 empty as pump blend is now premixed. I call it "shit my cordial is now too strong" theory.
I did get advice to fill it with 12L of e85 and 28L of P98 to combat this on the continual 1/4 tank left fills after tune..
Does this make sense? Oh ...who cares just fill the ****ing thing already?
