Fuel Mixture


Recommended Posts

Just got a Banshee a few days ago, first one ever owned and this may be a dumb question but here goes. Im using Amsoil High Performance Interseptor oil and the guy i got the Banshee from said to mix 1 gallon of gas with 2 ounces of oil but i've read and others say to go with the 32:1 ratio which is 4 ounces to 1 gallon gas. Which is better or which one should i do??

2oz of oil to 1 gallon of gas is 64:1 .. WAAAYYY to lean... mix at 32:1 (4 oz to 1 gallon of gas)... use Klotz Supertechniplate or Klotz Benol ..

Also, when buying premium from the pump for your Banshee, always put 2 or 3 gallons in your car or truck first, then your can, or your gonna get a couple gallons of cheap gas from the last guys purchase. Those gas pumps and hoses hold alot of fuel from where the thing switches fuel grades when you push the "91" button.

Or just go to a different gas station with 3 nozzles

Interceptor is formulated to be mixed at 50:1 which is 2.6 oz. oil per gallon of gas. I would recommend mixing it at 50:1. If you read Amsoil's literature on the product they tell ya right there, mix it at 50:1. If you listen to the other guys who tell ya to mix at 32:1 and you were originally mixing at 64:1(2 oz per gallon), then you are going to create a lean air/fuel ratio and you'll have to re-jet, or at the very least you'll have to fiddle with your air screws and keep a close eye on the main jet.

 

Remember... if you add more oil to the fuel/oil ratio, you lean out the air/fuel mixture.

 

Stick to the 50:1 ratio and keep an eye on your jetting for a little while....

 

Buy a ratio-rite cup with a lid. Hell buy two of em...

I never understood why people have opinions on the mix ratio of a product that it formulated to be mixed at a certain ratio by the manufacturer. The chemists at Amsoil didn't just pick 50:1 out of the air. When guys say stuff like, one ratio is too lean, one ratio is too rich, I don't understand how you come up with that. Lean and rich air/fuel conditions are adjusted by jets, you adjust(re-jet) your air/fuel ratio to accommodate the manufacturer's recommended fuel/oil ratio. Now if the oil manufacture doesn't have a recommended mix ratio, then we can have a conversation about the appropriate mix ratio. Years ago you would have a hard time finding any info about the oil manufacturer's recommended mix ratio information, but now you see more and more oil companies putting their recommended ratios on their oil bottles. Looking at it from a business standpoint, the oil companies would rather see you mixed at 32:1 versus 50:1 because you need to buy more oil at the 32:1 ratio. Klotz Super Techniplate for example, tells you to mix at 20 to 32:1 for air cooled motors,and 32 to 50:1 for water cooled motors. FYI Klotz SuperTech is a blended oil, its not fully synthetic.

 

Here's where I think the confusion started. Years ago, as little as only 10 years ago or so, the majority of oils were petroleum based oils. Guys and companies like Yamaha and Honda would use/recommend mix ratio's of 20:1 or the old standby of 32:1. They did this for two big reasons that I know of, one is the idea that the extra oil is needed because of the lower protection offered by the older, lower tech, 100% petroleum based oils. The second reason is because years ago cast pistons and iron bores were used, so you wanted more oil in the combustion chamber to protect these two parts and help seal 'loose tolerances'. But hell, its 2012... with Nikasil liners and a fancy forged piston, tolerances are closer today than they ever have been so you don't need that heavy coat of oil.

 

TLDR; Someone tell your mix ratio that the year is 2012 not 1986.
