what synthetic oils are out their, how much are they, and where could i order some?
im hopeing for stuff in the 25 buck per gallon range im not sure if they make anything that cheap
i know there is klotz but its expensive
im planning on mixing this 50-50 with castor so if its not the best oil i dont really care, also if their is something cheap that you have to buy in bulk, like 5 gallons for 100 bucks, im fine with that as well.
out of random curisoty i mixed valovoline 5w40 synthetic motor into some methanol and it mixed just fine and has stayed in solution for more than a month, i dont know if i could run my engines with that stuff mixed 50-50 with castor.....is it worth a shot?? i have a few old bushing engines i could try it on. its cheap....like 20 bucks a gallon....who knows if it will carbon like crazy though.
If you're just looking for cheap oil to mix your own fuel, the best thing you can use is Castor oil. Synthetics work well, but when they vaporize and fly out the exhaust port, there's not much left to protect the engine. Running a 50/50 castor/syn mix is a good way to go, but the synthetics are expensive. You could use the automotive oils, but they are of a higher viscosity and may make fuel draw a problem. If it were me just experimenting, I'd try 0W synthetic oil (Thats Zero weight) instead of the 5W40. Theory being when the oil is cold its 5W and when warm its 40W but I think that multiviscosity stuff to be joke, really. (I may have it backwards but either way it may still be problematic..)
Why not just run all castor? Its $23 a gallon from SIG. You might even find it cheaper elsewhere. It does make a bit more of a mess, but engine longevity is key here. Model engines started running on all castor oil. Doesnt hurt a thing!
Just my readily available $.02
