Maintenance on E85

[stannypack]

I plan to daily drive my car on E long term, was wondering what should be done for longevity.

I read filling up with a full tank of 93 every maybe 10th fill up for the detergents is a good idea (I fill up once a week usually).

And how about adding Lucas ethanol fuel conditioner for the lubricants every other fillup? Lucas Safeguard™ Ethanol Fuel Conditioner (lucasoil.com)

I would like to know as well. I've been running E85 exclusively since I got the tune and I don't really want to run a full tank of 93 but will if I have too. My daily commute is short (2 miles if that) so E lasts a while for me lol

that stuff is for E10. Myabe Rev-X E-Boost E85 and alcohol additive.
lot of good reviews, I just ordered some Rev-X. LOL

I have been daily driven mine for about a year and a half.

I check ethanol content once a month.
I add Lucas Oil Ethanol Fuel Conditioner every once in a while.
That’s it

Ooh I found this in the F150 manual

seems that 93 every 10th fill up might be a little excessive lol

oh ok, I just looked at the pic. The Lucas is a bit cheaper. Maybe I will cancel and give that a try instead.

UPDATE- cancelled that too after seeing the flounder below. Lol

I use alcohol top lube. Same stuff the methanol racers use. Couple oz's every few tanks.

Is adding lubricants necessary or just a myth?

I like to add it for the fuel pump. Also makes the injectors live longer. Is it necessary? Probably not.

The reason for the regular gas every oil change interval in the F150 is for lubrication. Also, would suggest not using the Lucas based on this:

They recommend MarvelMysteryOil instead. I add a few ounces every couple tanks and havent looked back

 

[K4fxd]

I'm sure Marvel is cheaper than what I use. Anyone try it and see if it mixes with alcohol? Most oils I tried separate out of ethanol.

Put some e85 in a mason jar, add a few oz's of oil, shake it up and wait a day or 2. If it stays mixed , good to go.

I been on pump E85 since summer 2019 without any issues. Just change your oil more frequently if you drive mostly around town. Other than that, I don't use any additives, just send it and don't overthink it.

Also, would suggest not using the Lucas based on this:

I ran from Lucas products years ago when I saw a diff with their additive added. The diff had a clear rear cover. After about 10 seconds of running it was nothing but foam. Trapped a lot of air
