I am also running 300x's and have a concern that 91+ is going to be hard to find in one of the area's I boat. Im under the belief that 89 is out of the question.
Is this TK-7 stuff safe to keep on board or is it highly flammable. I would be interested in keeping a few gallons on board to add if the fuel I was putting in was questionable.
Thoughts?????

Are there any other octane boosters that work?

Any body know a good way to transfer gas from them instead of holding them by hand. Thanks for info.

Where did you see 1 oz./ gallon, on the link Firewalker gave it says 1 oz/6 gallons. that means a gallon will treat 768 gallons of fuel which is only $0.15/ gallon of treated fuel, if the stuff really works it would be cheaper than buying 92 all the time. I just don't know if I trust the stuff????

The maxlead 2000 at $30/gallon comes out to $108 for the same amount of treated fuel their website is http://www.maxlead2000.com/

There is also Octane supreme 130, their website is
http://www.kemcooil.com/product_info.php?pId=61

A friend has used Maxlead 2000 in his 440 that needs 104 octane to not run on at shutdown and it worked in it, that's the only experience I've had with it.

I looked at the Gas caddie but at over 300.00 in the past it wasn't cost effective ...fuel dock 10 mins from my dock is @ 2.42 for 92 octane and 20 mins away I can get 93 for the same price or usually less ....92 at the pump is running almost the same if not more ....plus your looking at over 200lbs for a full caddie ....

I have 200 gallon tanks, got four - 6gallon cans thats 24 gallons. I fill up before I go to the boat dump fuel in. Drive 1/2 mile to the gas station and fill up another 24 gallons. I never run far enough to burn 200 gallons, so I usually only put 48 gallons in at a time depending on weekend usage and how low I run the tanks. It is not bad, especially if it will save your motors. ALso I took off the oil injection for reliability, so I dump a 1/2 gallon of oil between the 4 cans and pump 24 gallons, for a 48:1 mixture. The gas is cheaper on land too, obviously. It may be a little extra labor but it will save your motors and your $$$$. Buy more cans if you dont have a close station. $5 a can is cheap!!

Just got off the phone with the Merc guy and he still reccomended AV in the Havasu heat. He said that losing a motor due to low octane was more of a concern than AV being "dry". He also said to mix 50/50 of 91 and AV unless the motors will be run hard and in that case run straight AV. Everybody has different opinions but I will stick with what Merc says.

Never thought I'd say "those were the days" about $2.42/gal but those were the days. Just goes to show what a porking the American public is getting now.
