So, are you pre-mixing both or are you just making up for the alcohol premix by adding a little extra in a e85?

No I am mixing both, I don't want the meth system eating itself.

7-8oz pre-mix per tank of pump gas...... So I'd go a little more for e85.

i think that if gas can mix with alch. then regular premix will mix with e 85.

mix it in a bottle, and leave it for a month and see if it breaks down or sags.

6 years, but what about the milage?

Fuel contains some lubrication, but 100% it needs some extra combustion lubrication.


Your turbo was leaking oil, or your oil seals were leaking, maybe?

Blume recomended a specific oil on C2C the other night for 2 stroke engines running ethanol. Chances are it might cross over for rotaries. I forgot the brand, but did order the "big book" so as soon as I get it - I will update.

But yes, in many other cars, you just pump it in and forget about it.

hey to all im new to this rotary engine thing lol
i have a 87 rx7 non turbo that runs premixx and i have know idea what im doing so can you guys get me back on my feet!!!
plus anytips on just wat to look out for and wat not to do would be great

Silkolene pro Castor oil R50. Has someone used that before?
Dumb q, but if it mix with meth it will mix with E85? It is made for meth and petrol bikes.

Dane

I would think so since Ethanol is very similar to Methanol...yet non-corrosive.

If it is intended for alcohol fuels than yes it will mix with E-85.

There is a whole chapter on two-stroke lubricants (being used with Ethanol) in "Alcohol Can Be A Gas", but since my scanner is no longer working, I cannot scan it. But when speaking of Redline Synthetic 2 cycle oil, the author says, "Although the bottle is market for methanol only, the oil is equally soluble in ethanol" (p.427).

That would likely apply to others. One thing I did find interesting is that the only problem they ran into using this in a chain saw is that the ethanol actually cleaned the combustion chamber up to the point where the motor had to be re-tuned.

Another interesting thing I read just now in the book (that I didn't know) is that one can actually add 2 stroke oil to a 4 stroke piston engine *if running ethanol* to "extend piston ring and valve life".

id like to see something thats E85 compatible that isn't 7-9$ per small bottle. I'm all for paying for the high end parts/fluids when necessary but this is a bit ridiculous! There's got to be a cheaper one out there that is alky compatible. we should all test some and see if we come up with an inexpensive premix that is soluble in the E85. I would imagine non racing/performance brands wouldnt take the time to proclaim they can be used in alcohol fuels or not.

I have been buying Klotz Benol by the gallon and transferring it to smaller injector cleaner bottles. The injector bottles get me close to the amount I want to pre-mix 12 oz/12 gal and have a long and skinny enough neck to open the gas filler valve at the top of the neck. A gallon (128 oz) is basically 10 fillups and cost $45. Compatible with alcohol and $4.50 a fillup is fine by me.

Dane

Whatever research they did was likely years before the availability of ethanol fuel to the general public. This being the case, I doubt they see the market to go back re-research everything.

exactly, id be willing to bet there's a cheap wal mart style premix out there that's like 7-8$ per gallon that will mix with methanol, but wed have to find it on our own.

I've started an oil separation test using E85 and Pennzoil Multi Purpose 2 stroke oil. See the following link for visual progress.

As expected, major league FAIL. Oddly, the dye stays dissolved, the oil does not. Could be misleading on casual inspection. I don't think the dye is a very good lubricant... To those who use castor based products - have you seen any excessive carbon deposits in the exhaust or gummed up seals? Way back when I competed in MX, the Castrol R50 we used in the 2 strokes mandated a top end teardown every 10 hours or so due to the above problems. Every 20-30 hours or so you'd have to take the expansion chamber off and heat it with a torch to get the castor oil residue to ignite and burn off so the chamber would do it's job. I do miss the smell though!

OK another question, if i use an OMP adapter to meter in premix, regular TCW-3 should work fine, since it isn't mixing in with the fuel... correct?

Dane

This shouldn't be a problem using E85...as it has a cleaning effect...well beyond the rate of (potential) deposit, I would think.

pmrobert

Good point - and the castor oils of today are apparently "degummed" as well to decrease carbon deposition, so they say. Thanks for the input...

Hey Mike,
Did you happen to do this test with any "alcohol compatible" lubricant?

ill have to pay attention to this one.

I'll be doing the time lapse photo thing on Benol next, starting Wednesday. Many people say it works just fine, just want to see with my own two eyes...
