10% Ethanol Question

90% Not sure

If I put 10% Ethanol in my bulk tank, should I expect any trouble from my old tractors as far as old dirt and varnish getting loosened up and messing with the carbs? Or stuff in the bulk tank getting loosened up and pumped into the tractor? I've heard others say not to use it on these old tractors as it acts like a detergent and will cause major headaches for awhile. I also fill my lawnmowers, atv, snowmobile, generator, weed eater and other small engines from this tank.

Ever since I have been using 10% ethanol I have had a terrible time with fuel lines. The ethanol seems to eat away rubber fuel line. I have had to replace fuel lines in almost everthing including weed eaters, tractors, trucks and lawn mowers.

Theres some things best not to run any ethanol in.

It takes twice as much ethanol to do the same thing gasoline will do. Gas = 14/1, Eth = 7/1 A/F ratios.

X% ethanol = X/2% lean condition in carbureted engines. Carbureted can't adjust the mixture like EFI engines can. You run E10 in a carbureted air cooled engine without richening it up on a hot day and you can have overheating.

EFIs will make the adjustment fine.... at the peril of your fuel mileage.

Just like above, X% ethanol = X/2% LESS mileage.

I just think all the ethanol promoters are omitting some of the real truths about E85. When I see E85 I really see 42% lower fuel mileage for the same pump price PLUS nearly 50 cents a gallon subsidy our tax dollars are paying for. They never seem to mention that.

I think E85 is BUNK. Its helping the corn farmers and the distillers just fine, but hurting about everyone else.

Hello,
My 530 159 gas engine requires 90.8 octane. I"m assuming all the old case gas engines are similiar. I don"t understand why when the compression ratio is only 7.5 to 1. Checking the octane requirements on all your equipment may be a good idea?
Best wishes, Dennis..... .

I like E10. But I don't burn it in my JD 4020 because it stumbles with it.

Older engines and vehicles often used fuel system parts (pump diaphragms, gauge floats, carburetor floats, gaskets and seals) that didn't stand up to ethanol well. Fewer stood up to methanol (wood alcohol) which some petroleum companies preferred to use. Filtering at the supply tank won't prevent the ethanol from softening cork float varnish not made to handle it and that varnish then plugging up carburetor passages. I have a WW2 surplus generator in the back of the barn that happened to.

Small engines seem to be more of a problem, probaby because of varnish in their fuel systems from sitting there long periods between uses.

I've been running E-10 in my road vehicles ever since it became available in Iowa back in the mid 70s. My '73 Pinto wagon needed a new float for the gas gauge later in life. It was plastic foam, just failed to float. Every vehicle since has run smoother on E-10.

Hey there Not Sure;
I can't say that i'm an expert,
but I would think,if you put a
filter,ahead of the nozzle you,
can eliminate your worries. Bob

Up here in the great white north ( Canada) most of our fuel already has up to 10 percent ethanol. It doesn't cause any problems with my older equipment as long as the fuel system is clean but it DOES swell O rings, causing sediment bowl gaskets not to fit, if they are not new type ones, and it can cause tank sealer - the old yellow stuff- to soften and dislodge. The red sealer seems ok. A family member has an older aircraft with a Continental engine which is approved for auto gas, and we quit using it 'cause the drains wouldn't open and it didn't run as smooth as avgas. The old Gasoline (no ethanol) was no problem.
