didn't want to start a new thread, but i had a question about lamp and candle oil. i found a (not quite full) half gal container of the stuff in my new house and was wondering if i could use it in my car or mower. thoughts?
I would not use it in an engine. It may contain small amounts of paraffin dissolved in it. This may lead to nasty deposits on valves and fuel injectors, and possibly fouling plugs, O2 sensors, and catalytic converters.
Ever since the 70's, in the old thunker 100 gal 2 piston compressor, to the modern 10 gal portable shop compressor, I have always used non detergent 30 wt oil. Never had a problem, just change it when it looks funky.
I dont know about using it in a car. I still use 90% multigrade synthetic, with 10% 30 wt oil to protect the bearings during start up.
