Wow thats a big statement. first of all nobody is going to use pump gas in there Warner engine. Most pilots are not that dumb. And there is no STC. for it. and as for your statement above I received my schooling from NASA. Aerospace research and development as a Liquid Fuels specialist 63130 and pass top of class and top 3% of all government employees. I went on to work for Aztec oil exploration sub company of shell oil as a top seismograph driller and over saw the drilling and exploration of 13 drill rigs and 111 people and took seismograph readings through out a 5 state area. I was also employed by are goverment and still on a yearly retainer. Good luck on finding that more knowledgrable person. chances are if he went to school he used the books I wrote. One more thing I will never use pump gas in my 1938 warner powered 24. But that coming from a person that has so little knoledge in the field. NOW THATS FUNNY LOL.

If so, I'd like to hear from you." If you aren't using auto fuel in your Warner, or can't put me onto someone who does or has, no need to respond, thanks. --- In

Using less lead is better for the environment But not your engine. The lead is there for the lubrication and cooling and also acts as a rust inhibitor. The higher oct. is there to help slow down the burn/flash time and stop distortion. There are a couple dozen additives that are in avgas.

Subject: [fairchildclub] RE: Auto Fuel in Warners So Cy -- Maybe lubrication is not the right word. So whatever the terminology, then, using less lead is better, right? Wonder why we still have TEL in avgas -- probably not solely for octane rating improvement, as it is clear desired octane levels are being achieved without it in gasolines formulated for ground vehicles with much higher anti-knock requirements than the naturally aspirated, low compression engines in our small aircraft. Wonder why engines intended for unleaded fuels use exhaust valve seats made of material of higher hardness (actually toughness) at given temperatures -- and no, head temps are not higher with unleaded fuels. Why do engine designers tell us such materials are necessary to combat valve recession in engines using unleaded fuels. Is it just a scam to promote the use of more exotic materials? Let us know. Read this:
http://en.wikipedia.org/wiki/Tetra-ethyl_lead Is this just more disinformation? So, are you using auto fuel in a Warner or any other aircraft engine? Thanks.--- In

Subject: [fairchildclub] Auto Fuel in Warners Anybody out there using auto fuel in a Warner, particularly a 165, or can put me in contact with someone who does, or has? If so, I'd like to hear from you. Petersen STC's are available for my 24W and Warner 165 combination. I am contemplating using a mixture of 75% non-oxygenated (zero alcohol) premium auto fuel, and 25% 100LL avgas. This combination will have the same amount of lead contained in 80/87, the recommended fuel (proper valve seat lube), and be unlikely to have less than the 73 octane minimum specified for the engine. Thanks.'
