i made a version of ed's oil that works great. it's 50/50 ATF dexron3 and kerosene k-1, with 250g of lanolin hydrous added per 2 litres of gun oil mix. lanolin is easily melted in a double boiler first then simply poured into the mix. give it a stir and it's done. will prevent rust on a stored arm for 2 years plus.

Out of curiosity I found CE Harris's notes:

He doesn't mention adding water that I can see.

(Optional up to 1 lb. of Lanolin, Anhydrous, USP per gallon, OK to
substitute Lanolin, Modified, Topical Lubricant, from the drug store)


Mix outdoors, in good ventilation. Use a clean 1 gallon metal,
chemical-resistant, heavy gage PET or PVC plastic container. NFPA
approved plastic gasoline storage containers are also OK. Do NOT use
HDPE, which is permeable, because the acetone will eventually evaporate.
The acetone in ER will also attack HDPE, causing the container to
collapse, making a heck of a mess!

Add the ATF first. Use the empty container to measure the other
components, so that it is thoroughly rinsed. If you incorporate the
lanolin into the mixture, melt this carefully in a double boiler, taking
precautions against fire. Pour the melted lanolin it into a larger
container, rinsing the lanolin container with the bore cleaner mix, and
stirring until it is all dissolved.

I recommend diverting a small quantity, up to 4 ozs. per quart of the
50-50 ATF/kerosene mix for optional use as an "ER-compatible" gun oil.
This can be done without impairing the effectiveness of the remaining
Don't mean to be a pain, but maybe you see it differently...
