E85 would be fine as a constant all year round, only in winter if u wanted better starting if u get cold there a bit more petrol will help, just keep track of your oil servicing as u may have to do it more often with ethanol as u dont want it sitting in the oil for too long over time, if u do excess cold starts/runs then change oil more often, if ur doing long full temp trips then can let it go close to normal just monitor it check dipstick in morning now and then and if its looking odd color wise or something is separating in it change it out
Considering full time E85 - How often fill with 93?
I filled up Wednesday with E85 since it was $3.19 and 93 was $4.75 at the same station. Costco is the only local station under $4.00 at 3.95. Most stations are 4.35 to 4.75 for 93. I've been reading posts from 2014 forward and find many different opinions. Some say use 93 after every 3-4 tanks of E85. Another said every 6 months. Others praise additives. These are too many opinions to list. I will continue to research, but is there a fueling routine that has some degree of consensus? For now I'll start with filling every 4th tank with 93. Also, it's probably the recent 70-80 degree weather but the V ran much smoother since filling with E85.

Clean injectors as regular maintenance for full time E85 especially if the car sits alot
If you have the inline filter it will help with the injectors like LT1Z stated. I ran it pretty straight for at least a year while back and one fillup/fuel change and bam injector fail on #6. It wasn't obvious at first, looked like O2 sensor failure etc. Replaced a lot of shit, injectors were last and the cure. Pain in the ass but I got very close to the car. Also be wary that extended usage can also cause your fuel gauge to stick at times, it can screw with the level/float arm in the tank. Oh and e85 feels like a cold front in the heat too. Have fun, be safe!

Also worth mentioning is that with a ~ 50% blend of e85 and 93 you'll still get plenty power gains with the detergents still there.

I’m with BlueCoupe, I rarely if ever fill with an entire tank of 93, just a 1/2 tank a few times a year.
It does get cold here on the shores of Lake Erie. I only run 93 in winter because I don't trust to gas station storage tanks to not absorb a lot of water. Talked to some owners and the demand for E85 is way down in the winter. Some stations even close their pumps.E85 would be fine as a constant all year round, only in winter if u wanted better starting if u get cold there a bit more petrol will help
I've been running straight E since my build (not many miles yet) and my build is effectively NOT a pump gas build..... at least as far as running straight 93 is a bad idea for me (don't get into boost!)
I am wondering though, and I'll need @Lt1z to answer this... what if I have to run, say, 50% 0r 30% due to spot availability or other circumstances... ?
Also, is it possibly a good idea (with MY build) to occasionally run half a tank of pump just for maintenance?

Your recommended method?Clean injectors as regular maintenance for full time E85 especially if the car sits alot
makes sense, I'm in Memphis, we go from a few inches of snow to 70 degrees in a three period in Feb, so not near the cold. Our E85 usually only test out around E70-75 summer or winter.It does get cold here on the shores of Lake Erie.

Elaborate on this? I've been having wonky level readings and signals since the build, erratic stuff.Also be wary that extended usage can also cause your fuel gauge to stick at times, it can screw with the level/float arm in the tank.

once i changed to injectors that were designed for ethanol (stainless internals) i never had any issues with them even sitting for long times but u can take them out check the tips if they are clean ur usually good, i think full affect of ethanol (as a safe knock resistant fuel) is made in the first 25-40% mixture, then after then it just aids more cooling and power, but thats where if u have a timing table dialed in for petrol and ethanol it can blend between them for flex fuel side so u should be good, or u can keep the timing safer with the blending until it get to the over 50% ethanol if u want a super safe tune.
the fuel sender should be kept cleaner with ethanol in the tank as it dosnt contain as much dirt so to speak as petrol only but if u were running petrol for a long time and then changed to ethanol that shift may cause it due to the light cleaning or dislodging of surface contaminates from petrol, but once ur on a constant mix or full e85 it should be fine, i think thats one of the biggest issues is if petrol was used for a very long time and then shifted to e85 it will dislodge the surface buildup from petrol on the tank walls ect but ethanol wont dissolve it so it stays in the tank and can cause issues depending how bad it is make sure u have a good filter but once thats gone and over with the use of both fuels regularly will be fine

just seen this pop should help some with there mixing %
Depends on hp level. With the GTR (1300+whp), I could pick up 200hp from E40 to E85. With my ZR1 (750whp) about 50. Not sure about the caddy yet.
I'd also be interested to see what is recommended for injector cleaning, remove and send out or an additive that is added to the tank and ran through during normal operation?Your recommended method?
