Sorry Yogi, I forgot to mention the price. In bulk from Caltex with my own drum the methanol is a bit over $1 per litre (I think my last one was about $1.20). Shell is a bit more expensive because they'll only sell in their own 20 litre drums.

Mobil have both the second and third generation oils still. I've never seen the latest one but I'd assume it's labelled as 3rd generation. A guy tried it and wrote to me telling me it wouldn't mix. One of our club members sells the Jet Oil for around $18 per litre.

That's interesting about the methanol being used to clean out the Quantas tanks. It could only be used to remove any moisture from the tank and I suspect it'd be the normal methanol like I buy. Sure worth a try!
