Just made up another batch of 10% ether fuel mix today.

I used both mineral oil and modified olive oil in the fuel mix in equal amounts.

I have no way of measuring viscosity but.......

The modified olive oil was such a beautiful golden colour when poured out, worth using just for the pleasure of seeing the golden liquid going into the fuel mix. It was poured out immediately after doing the mineral oil and I was sure that the modified olive oil was somewhat higher viscosity than the good quality car engine oil I use.

Something that looks as nice as that clear, golden olive oil MUST be good for my engines !
