Stewart / Reg

I took your advice and heated yesterday’s mixture up and it cooked up like normal BioOil, it lost its extra viscosity. So I capitulated and mixed a new batch of BioOil to test Reg’s mixture as posted on page (4) of this thread. I add a bit extra glycerin and cooked it on the stovetop this time using dishwasher detergent, cooking it until it went to an amber color, then put it into the Pressure Cooker. It came out white again, so back onto the stovetop and I evaporated out the water until it looked like normal BioOil. I can’t see any change at all on either mixtures. So I have to say the pressure cooker idea was invalid.

I can say you could use Laundry detergent or Dishwashing detergent. Other than that I was not successful at increasing the viscosity of Canola oil to any appreciable degree.

This oil will not mix with methanol in any percentage, but it mix with Kerosene fine.

It looks like Olive oil maybe your best choice. I hope these test increased the “Body of Knowledge” regarding BioOils.

Andy,

That’s one fine looking motor. I think the crankshaft and rod look much stronger that my suggestion of using a Ryobi string trimmer motor. The only two good points about the Ryobi are the hemi head and they are often free, but you now have a much nicer engine that a Ryobi.

I have used the cooker/antifreeze method and it works great, you don’t have to have a cooker, just a metal container and a heat source. It will take over night to soften the carbon, but the lighter stains will most likely disappear in about 6 hours. Keep the temp of the antifreeze below 200 F and you’ll be fine. You’ll notice the antifreeze will turn from a light green to very a very dark green indicating that the antifreeze has started to reach it’s cleaning capacity, at this time you can change the antifreeze and it will become much more active at cleaning again.

Any brand of antifreezes will work fine, so buy the cheap stuff. Don’t add any water, use it straight from the jug. It works fantastic. The engine will look like new in about 12 hours of soaking. You may have to use a little bit of mechanical force to lift of large chucks of carbon. I pull my parts every six hours and wash them in hot water and inspect, if the carbon is not soft I keep soaking. Extended soaking will not hurt metal parts, just don’t put any plastic parts into the antifreeze. Rubber is okay, but plastic will dissolve.
