I'm running e-85 in a sbc and was doing a tare down after having the engine together for 3 years. No oil would come out of the pan. When I flipped it over on the stand after having the intake and heads off, goo started to come out. I pulled the pan and had jelly like goo everywhere. I've been running Brad Penn 10-30. Has anyone else seen this with BP oil before? (or others?)
I'm looking for an oil that will not do this with e-85.
The oil had about 200 miles on it then sat for 3 months before the tare down.
Thanks..
have a pic but can't get it to post...

I've ran e-85 for about a yr now and have never drained oil out of my car that looks like what your describing. Even after setting 3 mo. Just changed it before the last race after setting that long and it looked pretty much like the day I put it in (maybe a little darker)but looked like oil and not jelly! By the way if you haven't hit the newbie thread ya might want to go there and introduce yourself before all hell breaks loose. I run valvoline race 20-50.

Is it black and more like tar? I'm really just curious now since jelly has me wondering if it's the normal broken-down oil?

I'm guessing you had a shit ton of water in your oil? Or alot of fuel?


I've allways ran Brad Penn 10W30 with alky and never had anything like that. Oil might smell like my fragrance additive or like alky but never any goo.

Come to think of it I had a cylinder filling up with water ( pin hole in cylinder wall ) and never had any goo build up. The Brad Penn oil wouldn't mix with it. Pull the drain plug and nothing but water until it was all gone, then oil would drain.



Maybe your E-85 mixes up with the Brad Penn?

if in fact it is from fuel or water in the oil i would strongly recommend you check ALL bearings in that motor. im surprised it didnt start knocking before it gelled up

Trust me after I seen the jelly gooo I pulled it completely apart. The bearings didn't look very good but not as bad as I was expecting after seeing the oil. I feel pretty lucky to tell you the truth.
Some new bearings and a little cleaning it will be good as new.
The only reason I was opening up the engine was just to look for anything funny due to the e-85.

OMG....I thought I was the only one seeing green JELLY in the oil pan with the BP oil! I had an oil pump quit working on me while the engine was running last year....cleaned out the pan after replacing the pump thinking it was bad and there was a 1/4" thick layer of green jelly in the bottom. Tore pump apart and didn't find anything wrong with it. I think the layer of goo kept the pump from pumping. Never seen that before this last year and been running BP oil for 2-3 yrs now. I run Q16 fuel. Its either the fuel / oil mix or most likely condensation in the oil causing it. Been thinking about calling Brad Penn about it....or sending a sample off to have analyzed.

WOW...never seen that with the Lucas in mine. I run the synthetic version though.....I don't have two hours to fill a quart of additive:eek:


I do change my oil and filter after every race also.

I have seen it a few times in diesel engine. It is due to lots of moisture in the oil. You stated your engine temp was 180, well what was your oil temp. Coolant temp and oil temp are two different things. Oil temp is very crucial on any engine, especially alky engines, and I can imagine e85 is no different

Yup....the oil has to get hot enough to "boil" the water out of it. Pop a set of valve covers off of an engine that's been started and shut off after about 5 minutes several times. Lots of milky, nasty looking oil....and that's on gasoline. Alcohol/Ethanol just makes it worse.

I can't see the pics now (office firewall)

Last time I went to empty my catch can I got a light brown/tan colored sludge in the bottom of the can that stopped up the drain flow. It was not as think as jelly - more like a light peanut butter both in consistency and color.

As to my oil - I changed it twice on short intervals after the motor was built (Sept 2010) and the oil looked fine. I've not changed it since March/April of 2011 (Amsoil Synt - only 2000 miles on it)

From all the readings I've done about E85 and oil - it's my conclusion that you must let the motor get to good operating temps for 20-30 mins to get the moisture that the fuel is absorbing (natural process of the alcohol) to evap out of the oil.
