Been running E85 in a 4G63 for 12 years plus. I cycle between periods of 91 & E85. The reason for the high carbon deposits on a E85 motor is that E85 is lacking, in percentage, the PIB cleaning solution found in regular high octane gas (PIB = Polyisobutylene). Injector gunk is very common on E85 run motors due to the low percentage of PIB. Learned this from a petroleum engineer.

My uncle bought a 96 dodge Dakota brand new. Changed his oil religiously every 3k miles. He only drove a few miles to work and home every day. I took his valve covers off after around 100k and his engine was pretty sludged up! He was very surprised but I explained to him that the short trips don’t evaporate the moisture out of his oil and that causes buildup. I think that truck is still running but definitely had some sludge issues. Short trip driving is the worst no matter what fuel you use!
The way you explain things, slowly, precisely makes it easier to understand, atleast for me.
Thank you for making this video, I feel like this is something that really doesn’t get talked about with e85
Thanks for this video! That's horrible and is an E85 nightmare. My E85 rules: - Don't let it sit for long periods. - Do oil more frequent oil changes. - Don't do lots of short journeys, cold starts will also contaminate the oil way faster. - Do longer trips to let oil come up to temperature and evaporate any water contamination. - Use flex sensor if possible and run some 93/98 petrol through from time to time. - Use a decent Ethanol stabilizer/additive to help protect against corrosion.

We typically drain the oil and fuel after a race. Fuel goes in a steel barrel and we swap gasoline back in and the oil goes into a modified water heater. It cooks the oil for 4hrs at 240f before shut off. Then ready for next race day. Obviously not much in common with street cars. A dual fuel system based on temperature would probably work best

Another great video Mike! Love all the detailed explanations.
I have a 2013 impala, I rarely run E85 in it, but I do drive city all the time, so it’s definitely going to cause more frequent oil changes. I was happy to see on my most recent oil change, my oil life meter was at 0% with 1800 miles left to go according to the oil change sticker which was set at 5000 miles. I run mobile one synthetic 5W30 but I always change mine at around 3000 miles due to my frequent short trips around town. Normally my oil life monitoring system seems to run me to about 5K before indicating a need for an oil change. This time it was around 3K at 0% life left. I guess the oil life monitoring systems are coming along because when these first came out, it would run people to 10k at times or more before indicating the need to change the oil. Thank you for this amazing video, and for sharing your knowledge with the world!

Very interesting.... never had it explained so well. The moisture build up sure makes a lot of sense.
On my older vehicles I still run conventional oil for this reason. handles moisture better. I did a video about converting my old cars over to 0-w40 synthetic but I dont think they make enough oil temperature to burn off the moisture. My modern cars oil temps go over 220F easy so there is no problems. Im going to monitor my Hondas oil temps this summer and see what I got and go from there.

My experience with small engine powersports has taught me even regular pump gas containing 10-15% ethanol will cause similar results with nasty oily gunk on pistons from PCV/crankcase evaporation & oil wash. Carbureted applications it's extremely noticeable, especially if you tune a little rich for safety. Not the worst part but more of a PITA is how fuel will evaporate inside the carb and the ethanol won't leaving a gummy residue that'll clog jet needle chambers, choke jets, pilot/slow jets etc.. Few reasons I run Non Ethanol premium in my bikes all the time and cars when I can.

For my Evo, I only use E85 during track days and go straight back to 98 after that, otherwise it fouls spark plugs, injectors and even rusts the exhaust. The condensation issue with E85 can't really be fixed unless you use it up regularly and drive decent distances weekly, it needs heat to boil away the condensation. C16 race fuel is the best I've used - clean and zero detonation, but E85 is much cheaper.

good to hear, thanks for your experience! I'm very happy to never run for any less than 15 minutes, but generally nothing less than 30 minutes. My engines are always properly warmed any time they're fired up.
This is why I have a flex tune for my car. My commute is sometimes short, and I try to at least let the engine run for a while to get rid of moisture. I try not to run e85 all the time because of the need for more frequent oil changes and the build up of moisture. I try to run 93 every 3rd to 4th tank of e85 because from my understanding it eats up the gunk that can form from the e85.
I'm curious how many total miles on the engine? I was surprised when you said it had oil changes every 2000 miles, this video was a major eye opener for me. I will pay even closer attention to the oil of my occasionally-driven cars.
I never even thought about this happening and makes sense too! Thank you
Excellent demonstration. Thank you guys.
We run E100 here in Brazil. Ethanol delivers better power due to higher octane rating. But we know it is harsher on the engine, it needs to be ready to deal with ethanol. It is recommended here to run a full gasoline (our gas means E25 actually) tank from time to time to help clean the engine. But tuners just change the engine to be E100 only, running more turbo pressure or, if it is a NA engine, modifying the header to run a higher compression ratio.

Good things to know, thanks for the heads up! I don't think I have much to worry about for my track day car since I'm constantly changing the oil, maybe I should look at some of those fuel stabilizers that are suppose to keep the amount of water absorbed in the alcohol to a minimum.
Can confirm this with carbon build on a engine that I built and was running E85, the tuner I used at the time (many years back now before I started tuning myself) tuned it with excessively low lambda/AFR with pretty mediocre timing advance for no good reason and didnt tune anything regarding the transient fueling as intended. Basically washing the oil film off the cylinder walls and all that. The piston crowns were completely covered in sticky carbon crud as well as parts of the piston ring land. That engine was filthy inside after just 5000km with two oil changes and a lot of longer drives. A lot can be avoided with proper tuning and stop using excessive AFRs/lambdas except for those short drives which are the worst and always will be bad. Now doing everything myself I havent experienced this type of carbon build anymore.

Absolutely right, even the garage kept cars need a long drive every once in a while to burn off the moisture and liquefy the sludge. Motor flushes at each and every oil change would be a wise practice on these low mile, low use engines. I try to take my cars for a long (1 hour plus) freeway drive before doing the oil change to get everything hot and hopefully drained out of the oil pan. I have used routine motor flushes and Seafoam in the crankcase of badly neglected vehicles to un-stick rings and noisy lifters with great results and improvements.

Thanks for sharing your experience with e85.
Sage advice from Saint Mike, patron saint of the gearhead. May the car gods bless you.
Honestly looks to me like the oil never got hot enough to bake off dissolved fuel in the oil. Small amounts of blowby do deposit some fuel into the oil and tend to acidify it over time, but most of that fuel vaporizes and gets sucked up by the PCV system to be burnt again. And as soon as the gummy ethanol rich oil started to gum up and deposit on the rings, the excess blowby accelerated the contamination of the oil dramatically, causing a feedback loop where it just got worse and worse.

Good stuff. I suspect this is one of the reasons Ford recommends running a tank of gasoline at least once per oil change in the flex fuel F-150 5.0 engines. Although this video has me questioning whether that is frequent enough. In my case it's not really a concern because I end up switching fuels more frequently than that just because of variations in cost and availability.

Been using e85 in 4cyl cars for 10 years now. We live by oil changes often. Most these cars make well above 500whp and oil is changed at longest every 1k miles, most even more often, injectors flowed and checked often, anytime the engine starts the car runs up to temp to burn off moisture. Have never had any issues due to being very fussy with what we do.

I love ethanol content, I'll give my experience, here in Brazil i have a fuel injected 125cc street bike that can run on E25 or any blend of ethanol up to E100, the bike has 28k miles and mostly ran on pure ethanol with few times on E25. I use Motul 5100 15w50 and in the last oil change I opened the side engine cover and the oil pan is very clean, only small traces of water mixing with oil, I change the oil every 1300 miles. I'll have to replace the spark plug soon and will take a look at the piston. And here we have E100 and E100 with additives, available, I mostly run the additive variant (they claim to have corrosion inhibitors, friction modifier and detergents).

Insufficient crackcase ventilation is often a factor here as well. Water and other combustion byproducts degrade the oil. When the oil doesnt get hot enough, it can't evaporate the water. And restrictive breather setups will reduce the evaporation rate even when the oil is up to temp.

I love this man. Thank you for sharing your knowledge. Could listen to you teach forever.
This guy is the best!!
Great video....I was told I should go e85 on my hellcat redeye, but I dont drive it that often as its not a primary vehicle....I will still with a 93 tune with boostang additive

I run 93 every now and then. More frequent oil changes too. When I'm on 93 I don't get on it because the car is tuned for E85 only.

If its tuned for E85 then its crazy rich on gas and you are in danger of washing down your cylinders and fouling out everything! Convert to flex fuel before you mess something up!

Surely you just run the tank of e85 emptyish then fill up and run through some high octane petrol before letting it sit. Therefore it sits with petrol in the tank and lines etc not the e85?

@Ben Birch I run 1 gallon of 93 once a week once I'm completely empty on E85. 1 gallon once a week won't do any damage but it will keep things clean
great video , loved how u explained every thing 👏
Wow. Very impressed. I do think this is worse case. I’m hoping the rings on the race driven car on e85 never were glued shut.

I'm sure the heat from the race prevent that. More frequent oil changes are a must on the alcohol cars.
Without resorting to jerk status and bringing up the 'EJ Disclaimer', short trips are the death nail for pretty much any IC engine. I've been round and round with a lot of Toyota folks with short trips eventually leading to oil burning rings, especially in the low tension era. You pretty much nailed it across the board though. Ethanol isn't exactly and every day wonder fuel outside of specific conditions that everyone wants it to be. And that's just covering how hard it is on the fuel system by itself! I've not seen that kind of build-up in the oil system, but there's a first for everything, right?

I was surprised when he said it got frequent oil changes, I wonder if using a motor flush at every oil change would have kept the internals looking good or if the moisture still would have wrecked it?

@@davidparker9676 Honestly I don't think anything short of pulling the pan would have given an advanced notice that that much sludge was down there. Chemical flushes *might help to a small degree (once you're aware of the problem of course), but without added pressure over what the vehicle's oil pump can supply, you're only going to dislodge what a topical rinse would move. Nature of a hygroscopic beast unfortunately.

@@C-M-E I agree that this would have blindsided me as well. He never mentioned how many miles were on the engine, but he did know to change the oil more frequently due to using E85. I think that going forward, a chemical flush at every or every other oil change would be wise in such a scenario. It seems that the rings get gummed up first and accelerate the rest of the problems.
Since both of my primary vehicles are 20yrs old, I let them warm up at every start up (let them idle for 10-15mins) before I drive them and if it's just to move one around on property I still let it warm up (one is a 3rd Gen T4r and the other is a '01 Jeep WJ). With the way gasoline is now 90/10 petrol to ethanol or in some cases 85/15 mixtures, I want things to get up to temp since E can generate moisture.
Thank you so much for sharing and all of the comments. I am going to start balancing E85 and 93 octane pure gas in my ROUSH. Thank you!
Good information to have as I’m planning to move my car to a higher E blend soon. I drive about 5 miles to work every day and take long trips every weekend so I should be okay. Though my plan to do 3k mile oil changes has been changed to 1500 miles

if your oil temps get above 220F that should be enough to burn off any moisture in the oil, but you would be surprised how long it take to get oil in an engine to that temp.

This relates to another comment about detergent additives being in the gasoline, but not the ethanol. E85 is only 15% gasoline.
