Don't get me wrong, I think it's a great idea for people to be able to go check out any exotic chemicals they want to try in their fuels (and virtually everything has been tried at one time or other) but what I'm saying is that the data should be read carefully to see how dangerous it might be in our use.

Take Mobil Jet Oil 2 which seems to get picked on all the time. Here's a quote from the test that caused the most damage.
"Repeated oral administration of 2 g/kg of a generic jet engine oil containing 3% tricresyl phosphate (TCP) (once/day, 5 days/week for 10 weeks) to hens (60mg/kg/day TCP) inhibited brain neuropathy target esterase (NTE) by 70% and caused ataxia or paralysis in 22 of 30 hens in this treatment group."
Basically this means don't drink it. Other than that, where is this so-called danger??

Yes, I use Mobil sometimes and even George Aldrich said it was the best oil he'd ever come across. No, I don't breathe the exhaust if possible because it smells bad and it's got all this unburnt methanol vapour in it and that's the stuff that worries me.
