I put STA BIL in my gas all season. It helps get rid of the water that the new Ethanol gas attracks. I get no ping and the motor runs sweet.

 

LOL, just don't do what this guy did. It turned into an epic thread . . .

Well that is a hell of a read, 2 million hits and 148 pages long, it has even surfaces on the Honda civic forum. I registered just to be part of the Gunness record

Try a little seafoam every now and then, just a few ounces will clean out teh fuel system

 

Just a little reminder because there are still loads of people who don't seem to get this...

High octane fuel isn't "the good stuff". It doesn't have more go or generate more power, especially for engines not designed for it. A lot of people think that because it has a bigger number and costs more then it must be best - wrong.

High octane fuel simply contains more anti-knock chemicals, which lengthens the time it takes for the fuel to burn after the spark and prevents it starting to burn due to just compression.

If you have a high compression engine then you need more octane. Otherwise you don't. If you put high octane fuel in an engine not designed for it then you can, in fact, rob the engine of power because its harder for the engine to get an efficient burn.

If an engine that is specified in the owners manual as requiring normal fuel and you haven't modified the compression and get pinging then you need to fix the reason for the pinging, not just throw high octane fuel at the problem.

 

I've used this for years

+1 Exactly so. Octane is NOT a performance enhancer. It merely retards the fuel from detonation due to increased compression!

 

Marvel mystery oil, great stuff, used it for years

 

It's still growing.

 

Octane boost...you have your answers above....waste of money.
Injector cleaner....in the early 70's it helped at times, just like stabilizers. But these days, they put so many detergents, cleaners, water removers, and other crap in gas....you're really just pissing money away adding that stuff.

Decades ago, whenever I was winterizing an engine, yeah I'd put storage stuff in the gas..else the engine was a pain to start the next spring and often required cleaning the carbs. But these days.....all that stuff is already in the gas, and then some. Has a tremendous shelf life now. I don't do anything special to store engines now, and in the spring they fire right up!

 

What is considered high compression. I think my SB stock was 9.2:1`,

After the build, 103" w Andrews 54h cams I think it is about 9.9:1. Is that high? or would you say greater than 10:1?

just curious.

Also, i use 92 or 93 octane depending on availability as the manual called for 92 octane or greater with the stock set-up.
