Does ethanol (10%) make a small engine run better or worse

These charts say otherwise.

The rubber chemical resistance charts do not speak very well about common chemicals found in gasoline, like benzene, xylene, or toluene. Ethanol looks much, much better.

Ethanol has less energy and is bad for rubber parts in small engines. Also, the life of this fuel is now about 45 days before it goes bad according to my Stihl dealer.

I still have not had any problems with my mowers due to using gasohol. I do have to sharpen the blade occasionally.

Ethanol is NOT beneficial in any engine, especially small engines.
Here's a little info I found about ethanol in small engines.

"Ethanol turns to gum residual if sat for too long. Small engines are venerable due this to this"

Actually this is a false statement. It is gasoline that leaves a gummy residue after evaporation.

"Many later products are probably made with parts which are ethanol tolerant materials but older engines may suffer." That is funny as my 22 year old mower runs just fine on ethanol fuels and has for over 12 years.

Whatever the benefits (small at best) or disadvantages (higher fuel consumption, damage to unprepared older engines) to engines, ethanol is a boondoggle lousy for the world: higher corn [food] prices and probably carbon positive when one takes everything into consideration.

Hi CORNHICK. I just purchased a commercial grade chipper/shredder on Thursday ($2054), after two weeks of reading about products and calling virtually every company. The three best selling companies (note: they sell many units under multiple brand names) have had to "modify" their engines after experiencing problems with E10. This was not rhetoric from a sales person, but information from two service departments and one Engineer.

My own experience validates that issue. One Honda engine and one Briggs & Straton Engine experience metal damage to the carburetors requiring replacement. The Honda carb was $75 and the Briggs & Straton was $50. I now have a source of EO and don't use E10. Yes, I did put fuel shutoffs on all of my engines and did run them empty, but the damage to the metal carbs was during normal use. You can purchase a lot of E0 for the $125 spent on those two carburetors. I should note that I've used Stabilit for years. Take care :-).

I work in dealership parts sales and thats the nature of auto parts . We saw lots of fuel injector problems as ethanol percentages increased and not so many issues in later years. Would hope manufacturers would make things with future fuels in consideration .

Actually ethanol in small engines is better. I just fired up my wood splitter this week and it had set for about 7 months with a tank of ethanol fuel, and it works just fine.

If you could keep the "correct fuel" out of wide usage, your lousy machinery would not matter much.

I was a National service manager for a Commercial Lawnmower Manufacturing Co.
In my ten (10) years that I was handling problems and going to Dealers open houses ethanol was NEVER the Main issue "FACT" you do NOT store ANY small engine with the fuel in it! You want junk the next year ignore the manufactures suggestion on this, store the equipment in a non heated dirt floor enclosed building and you get RUST WATER = junk. Ethanol does NOT have to be anywhere NEAR the Equipment.

Ethanol has been around here for 36years seem like the lies just keep getting bigger.
Also Acetone (it is one of the main additives in REGULAR GAS)eats your plastic fuel lines just go to the paint store and READ the warnings on the container.

Also some of you need to do some research before making FOOLS of yourselves.

My personal experience is that I have not had any problems what so ever running e-10 in my lawnmower. THis includes when it sits for the winter, although living in the Houston area we don't have a whole lot of winter. I have had problems with my smaller engines that use 50 to 1 or 40 to 1 gas oil mixes. These would include my weedeater/edger (interchangable heads), my chainsaw, and my gas powered blower. On the chainsaw I have had to rerun fuel lines several times because they turn to a gel. The weedeater/ blower I seem to get a new one every three years. I take it to the shop and the estimate for repair to the carb/ fuel lines almost always exceeds the cost of a new one. I can get a powerhead for my attachments for $69.99. The blower has been in the shop several times as well. Now I am no expert and don't believe everything people tell me but I know this. I don't have these problems with straight e-10. I only have issues with the ones that use the gas/oil mixes. I can't honestly say if its the ethanol, or the oil, or the combination of the two. I have started draining all the gas out of the engines if I will not be using it within a week or two and the problems have eased up.

But from my own personal experience something aint right because when I blended e-0 and oil for small engines I never had these issues. I have had outboard motors for over 40 years and that oil/gas mix never gave me any problems either till ethanol got added to the mix. Again I am making no accusations one way or another, just stating my actual experience.

The problem with ethanol in small engines is those engines that are not run very often. I have a DOA chain saw because it had some E10 put into it and I had forgotten to drain the tank before putting it away. I have tried to re-start it with fresh E0, but no joy. Time to take the carb apart and clean the whole thing.

1-3 hours of my time, vs. whatever false benefit is claimed by those who are restricting my freedom to purchase the correct fuel for my machinery.

Once it gets fixed, I am transitioning to the pre-mix fuel that is now available.

Yet, the Plastic Chemical Resistance do not agree with you mr. mechanic.

Plastic Chemical Resistance

or

Plastic Chemical Resistance

I suggest you check how plastics handle the common chemicals found in gasoline like benzene, xylene, or toluene compared to Ethanol.

Do you have something else to add, mr. mechanic? Do you need my help with understanding these charts?

Check you manual. If the engine is older than 15 years, they might not place a spec on the original manual, but good repair shops might be able to tell you.

Some older units that powered stationary systems (generator, pumps...) had some plastic seals that turned hard and cracked when ethanol hit them. Keeping up with maintenance can offset that, but more of a pain than good, I think.

Hey krzysiek_ck, someone spoke their thoughts so why don't you state someting of value here? All you do is poke at everyone else, but you still are a Bear's fan? pphhhhh

I find it funny that you still fail to post your personal experience when using Ethanol. How are your car, lawn mover, maybe snow blower engines doing while you use Ethanol in them?

Been using ethanol for years, my brother owns a lawn moWing service in Wi and has for over 10 yrs. He has several mowers and weed wackers and they all run on at least a 10% ethanol mix. He does 25 lawns per week and he reports no problems from ethanol.

there are many instances if ethanol gas damaging small engines. Recreational products may be very prone to damage due to them sitting for longer storage times. If i can find gas with little or no ethanol thats good.

After buying a new leaf blower today, the owners manual says that ethanol is not gasoline and should not be used. It specifically states that E-15 and E-85 and all blends in between should not be used but does not address E-10.

Minnesota has required 10% ethanol in gas since 2003. I have not heard of any reports about engines running better or worse and no reports about maintanance issues or exploding engines. My 30 year old lawnmower has been running just fine.

It definitely isn't good for small engines. One of my mowers says to not run more than 10 percent ethanol, and I don't know what we are going to do if they start putting 15 percent into this crap. I have already blown up one small engine this year and I am believing that it was ethanol because it had plenty of oil in it at the time. This engine literally blew apart through the crankcase. I can't afford to keep buying lawnmowers because of this stupid ethanol.

follow your manufacturer's engine guidelines. Most small engine mechanics will tell you to burn regular gas and not ethanol blends in small engines, becuse of potential dangers to small engines which are not manufactured for ethanol.
