Has anyone used an Octane boost additave to their fuel tank and is it safe to use on a first gen big block? I pull a bonehead move and put the worng octange gas when I went to fill up not thinking about the higher comrpession engine needing a higher octane. At first I thought I would need to drain the tank but I thought if the octance boost will work until I refill the tank with premium next time.

Mickey I use octane boost because in Canada the highest I can find is 94 octane (Chevron), for me it does make a difference. Some people would argue it is likely more of a placebo than an actual cure.

This is what I use:

How many gallons of lower octane did you put in? How many gallons of higher octane were already in the tank? Read Kurt's post in the thread that Ed posted, then you can decide how much you've lowered the octane in your tank. Worst case, you might just need to siphon out a five gallon can full and put in five of high test.

Back in the 70's during my racing years I asked Fred Egloff from (Fred's Trick Carbs) what he thought of octane booster. He said it had a bad habit of swelling the gaskets in the carbs. If you know Fred you would pretty much take his word for it, I know I never asked about octane booster again. Hope this helps, RonM.

LOL!

Sonny, there are SOOOOO many additives out on the market today and not ONE of them does any good. Walk into your local auto parts store and look at the chemical isle and you'll see oil additives, power steering additives, fuel additives, everything from seal expanders to stuff you pour into your carbutetor to "renew" your engine! It's ALL crap and just another way for corporations to separate you from your money. This junk generates billions for the manufacturers so why should they stop?!

Fuel additives are the worse in my opinion. They toute "cleaners" you add to the gas tank to clean fuel injectors and show these great pictures of "dirty" injectors and then "clean" injectors after using their product. What a load. Modern formulated fuel already has additives that clean the system. No reason to add anything else, but how many people do you know that pour a 12 dollar pint of that junk in at every fillup!!

Spark plugs are another irritant for me. Dual electrodes, quad electrodes... They perfom NO BETTER than the standard single electrode spark plugs. Electricity takes the path of least resistance and that means the spark jump from the center electrode to the ground electrode will be across ONE, not four! It's like razor blades. 3, 4, 5, 6 blades... when will it end??? I'm sure some day we'll see 24 electrode spark plugs and 24 blaze razors!!!

I'll step of my soapbox now, but hopefully I've saved someone out there a little $$$

Donít stop the soapbox on our account (many similarities on old vs. new). Iíve been using the 2- blade disposable shavers for as long as I can remember. But dad doesnít know what the heck heís doing. Thatís why my youngest son has mom buy him the 6- blade BB. He%#$, I didnít even know he had facial hair (one of those can buy me a years supply).

I put in about 10 gal of 87 on an empty tank. I am not trying to clean the engine, but trying to stop the auto detonation or knock when I turn the key off. I am just hoping not to have to drop or drain the tank.

What's the highest octane rating you can get in your area? If you add 8 gallons of 93, you'll be around 89.666. That might be enough, depending on your compression ratio. You may also have to retard the timing a little until you've had a chance to go through that tank. If you can get higher premium, go for that.

Here is a link using Wayback machine,not sure if you guys can still buy this stuff or not over there(company gone belly up?web page no longer works).
I have a couple of boxes left and still use this stuff sparingly.If you are looking to get your octane level up this this is the stuff Smiley
This stuff has real lead in it and if you put enough in you'll be blowing a gray pipe in no time.

There is a guy out here in OZ who can make this and is currently fighting his way through legislation so he can produce and sell it out here.

Edit:Just done a search and it would appear that you can still get this gear over there Cheesy Just search out Octane Supreme 130

Moroso used to make a good additive that I used in the 80's- nasty stuff though, it was had a carcinogen in it, but it did make a big difference in the car I drag raced back then.  Don't think you can get it any more though.   Personally I would drain/siphone the low octane gas out and put some 91 octane in it, surely that is available around you somewhere?

No need to drop the tank, just listen to what Ed and Sauron327 are saying.  The Sunoco Race Fuel site list dozens of places where you can buy high octane in Florida.  And that way you don't have to drain the whole tank either.
