Using Castor oil in scale gasoline engines
« on: April 09, 2019, 07:57:23 pm »
I was remembering afternoons by the motocross track, and the smell of hot castor oil wafting through the breeze- and I wondered if castor oil would be an efficient lubricant to mix with your naptha. I know of the benefits and detriments when used in high compression 2 stroke engines. Would the same apply with these low compression engines? My main reason for wanting to use it is the smell...that's just an awesome smell.

If they made 2 stroke racing oil air freshener, I'd buy it by the case!
Good idea by the way.

Only huge downfall I see is the tendency it has to gunk up- but if you are cleaning regularly, deposits shouldn't be an issue, right?

I would be interested in the answer as well, if anyone knows.

It should not hurt anything to try it that can't be cleaned up.


Remember these hit and miss engines tend to run cool and most of the oil is just pushed through rather than burned.
My point is simply that it might smell different getting partially atomized instead of burning well.
I have no idea if it would smell any different or not?

Thanks, Mr. Gil. I'm working on the video of the Vaughn so we can straighten that out. My laptop went south(disc read error) after I knocked it off my table, so I had to figure out another way to transfer files from the camcorder. Got it now, just need time to fiddle

I remember mixing castor oil into the fuel for model airplane engines back in my control line days.

A distinctive smell no doubt, and were I to catch a whiff of it today it would certainly open the floodgates on some fond old memories!

Here is a video from 2015 of an engine built by the same fellow that built my 2 Briggs FH conversions to side shaft hit and miss engines.


He mentions in the video running it on Coleman Fuel with Castor Oil.

I used to put 1/2 teaspoonfull, into my lawnmower's petrol tank.

Briggs & Stratton, never smelt so good.

Even the neighbours approved!  ;)

Think I'll try and source some Castor oil, perhaps a small bottle at the drugstore, and give it a try if a hit n miss ever shows up at my door. Heck, I still have some old model airplane engines lost in storage that I may try and drag out and give a spin one of these days, just for memories sake.

Benol is still available and smells the same! And claims to have reduced "gunking" on the bottle now.

Update on tests using Castor oil-

I've used Benol, still readily available, in both the Vaughn and Microcosm M90, for around 3 refills. I mixed 4 oz to 1 gallon white gas(camp fuel). For comparison, I have run Zippo fuel with a bit of Marvel in the M90 and Camp fuel with wd40 in the Vaughn.
 I can't see any difference in performance using either. Wear will need more run time to determine.

Oooh, but the Benol smells so good. I might go a bit heavier on the mix- just to be safe but it runs good now.

Hi
In Switzerland I use Rubin G8 Neoval Oil; good results on the Eachine little Miss engine.

One last note on using Castor oil- it will sour your fuel after about a month of being mixed. Don't mix large amounts, only small volumes.
