 two stroke on straght gas

Ethanol enriched gasoline is a huge problem for the aviation industry also.

Most ultralight aircraft these days are powered by a Rotax two-stroke engine, ethanol is deadly for these high performance two strokes and I'm told, has been behind several reported engine failures.

A friend of mine who owns 'power sports' store (boats, PWC's & snowmobiles) said they are having the same problem. In fact most manufacturers specifically state in the operator's amnuals for their two strokes not to use any fuel with more than 5% ethanol. He has been told by one manufacturer's rep. that they are to have the fuel tested in any product with a blown engine brought in for warranty work.

If the test is positive, the warranty claim is negative.

Best of luck.

 two stroke on straght gas

I emailed my friend to confirm I had it straight and if there was any change in the situation, here is an exerpt from his reply.

"Here is the official word, quoted directly from the owners manuals for some of the different products we sell.

The 2 strokes seem more susceptible to damage from the use of various oxygenators, but the 4 strokes are also vulnerable in many ways. As I mentioned before, almost every manufacturer has now told us to very carefully inspect and document any serious motor failures or problems BEFORE we do any repairs or even tell the client we will do the job under warranty.

Bombardier - CAUTION: The use of a fuel other than regular unleaded fuel can result in craft performance deterioration and damage to fuel system and engine components. Never experiment with other fuels or fuel ratios. Never use fuel containing alcohol, methanol or similar products including naptha.

Mercury Marine - Alcohol in Gasoline. We do not recommend the use of gasoline
which contains alcohol because of the possible adverse effect the alcohol may have on the fuel system. In general, Gasoline containing alcohol may cause the
following problems to your outboard and fuel system:
• Corrosion of metal parts.
• Deterioration of elastomers and plastic parts.
• Wear and damage of internal engine parts.
• Starting and operating difficulties.
• Vapor lock or fuel starvation.
Some of these adverse effects are due to the tendency of gasoline containing alcohol to absorb moisture from the air, resulting in a phase of water and alcohol which separates from the gasoline in the fuel tank. The adverse effects of alcohol are more severe with methanol and are worse with increasing content of alcohol


Nissan Marine - Note:
(1) Gasoline containing alcohol, methanol (methyl), or ethanol (ethyl), may cause:
• Wear and damage to bearings, cams, piston(s), piston rings.
• Corrosion of metal parts.
• Deterioration of rubber and plastic parts.
• Starting, idling, and other engine performance problems.
(2) Do not use gasoline that contains more than 10% ethanol or more than 5% methanol.
(3) Damage resulting from the use of gasolines that contain alcohol are not covered under the limited warranty

OMC - OMC products have been designed to operate using the above fuel: however, be aware of the following:
• The boat’s fuel system may have different requirements regarding the use of alcohol fuels. Refer to the boat’s owner manual.
• Alcohol attracts and holds moisture that can cause corrosion of metallic parts in the fuel system.
• Alcohol blended fuel can cause engine performance problems.
• All parts in the fuel system should be inspected frequently and replaced if signs
of deterioration or leakage are found. Inspect at least annually.

Suzuki – Suzuki highly recommends that you use alcohol-free unleaded gasoline whenever possible, with a minimum pump octane rating of 87 ((R+M)/2 method). In some areas, the only fuels that are available are oxygenated fuels. Oxygenated fuels which meet the minimum octane rating requirement and the requirements described below may be used in your outboard motor without jeopardizing the New Outboard Motor Limited Warranty.

Basically, the only two manufacturers that say it’s OK to use Gasahol are Honda & Yamaha, but they both qualify that by saying the fuel must contain cosolvents and corrosion inhibitors to protect the fuel system. To date we have been unable to find a gas company who add these products to their fuels since automobiles do not require them, just small engines."

With the cost of small engines, and the products they go in today, I don't think I'll risk it.

Best of luck.
