DF40 Gasoline

[rwarren3171]

I want to Know if the gas I bought at RaceTrac today is ok to use in my Suzuki DF40 outboard. I think it is a 2005 or 2006. The gas is E-85. Thanks

I would suggest not. E85 means it can have up to 85% ethanol. Suziki recommends 10% or less ethanol in the fuel. Octane difference?

e85

Ditto what Murray said, if you already put it in your tank I would suggest siphoning it back out! Personally I wouldn't put it in my car either unless that is what the manufacturer requires.

Your fuel question got me thinking, from a 2008 Hotrod article.

While the stoichiometric (chemically ideal) air/fuel mixture ratio for gasoline is approximately 14.7:1, with ethanol it is around 9.79:1. In carbureted applications you will usually need higher-flowing metering blocks calibrated for E85, while in fuel-injected applications you may need to upgrade the injectors to a greater lb/hr rating. In all cases, Ksiazkiewsicz notes, “You need to look over your entire fuel delivery system, including the pump and lines, to ensure it can deliver the additional fuel mass.” And while you’re there, here is another issue to consider: materials compatibility. Ethanol can be downright unfriendly to some traditional fuel-system materials-cork, for example. On late-model cars it’s not a big problem since they are already designed for fuel blends up to E20 (20 percent ethanol). But on older cars in particular, gaskets, seals, and hoses will need to be updated to ethanol-compatible materials, as in the long term the exposure will shorten their service lives. Also, aluminum fuel lines must be fabricated from standard anodized tubing. Naked aluminum corrodes when exposed to ethanol. However, ethanol presents no hazard whatsoever to oxygen sensors and catalytic converters-a definite plus

just about everyone recognizes the ethanol laced fuel has no place in the boating world

it is bad on the fuel lines. it attracts water and other undesirable attributes
as suggested. run it through your car
