I was thinking which sometimes isn’t a good thing.
Back when I was a kid pumping fuel at gas stations (16,17,18) I remember Amoco was selling the only unleaded fuel at the time. But also around this time most of our engines were in the neighborhood of 9.8 – 11.1 compression ratios and there wasn’t a lot of pinging and banging going on running the stuff. So now I am wondering what were they putting in that fuel to prevent pre-ignition and why we can’t have that today?
Also, it’s been a rumor I guess for a long time but I worked a Sunoco station for a bit and if you remember there was a dial on the side of the pump that would allow you pick the octane level you wanted. Sorta foggy now but I think the pumps ran from 140-260? Anyway, the whole deal was two tanks of fuel (one hi-test and one regular) that were being mixed right there at the pump. I worked this station mostly on Thursday – Sunday nights and on Friday and Saturday night I would lock out the outer pump to pure hi-test or 280 as it was referred to; no lower octane fuel was mixed with it. I would charge an extra $1.00 per 5 gallons that was pumped and had guys lined up in and out of the gas station. I made a little extra spending money and the guy that owned the station was impressed with how many gallons of gas I pumped every weekend once the word got around. And again, why doesn’t somebody do this now?
Lastly, I was wondering what happened to all of the gasoline, motor oil, battery and anti-freeze commercials that used to be on television? I think the last thing I can remember now is Shell running some commercials about the amount of detergents their fuels contained and their cleaning ability. Other than that one, it seems like its been a very long time since these type of commercials were out there. So the question I have is have the vendors of these products simply decided that either the motoring public isn’t really all that interested in any difference between manufacturers of these products or do they simply sell so much of their product that there is no gain in advertising it anymore?
