Petroil Mix
« on: August 12, 2005, 03:33:10 PM »
I have an old Francis Barnett Cruiser with a Villiers 17A engine (1935 ish).  I know the mix is 16 to 1 but what type of oil should I use? Is modern 2 stroke oil suitable?

No problem at all using a modern two stroke oil that's suitable for petroil mixing, you could probably reduce the ratio of oil to petrol as well, especially with a modern synthetic oil, but of course that's your decision.

Thanks...  
I assume that lead free petrol is OK also?

Using ordinary unleaded petrol should be fine as two strokes don't really need leaded petrol anyway (no valves).
Spark plugs can last longer too!

My 175 Bantam used to overheat on recommended oils at 24:1 I tried MOTUL 800 synthetic oil (same ratio) and she seems to run a bit cooler.
