Gasoline

Post by Gone Fishin » Tue Jun 24, 2008 10:10 pm

So should I be running premium gasoline in my 2 stroke outboard instead of regular? Is it good for it? Are there any benefits? The cost wouldn't be much different considering it would only be like a 1.25 a tank and would last a while

We have had this discussion before, and I would suggest that if you want the entire argument about fuel types, additives, etc., etc., that you do a search..................... but................

just my 2 cents worth. Check your owners manual for fuel requirements. I have never seen a 2 cycle that calls for premium, and if you use premium on any motor that is not designed for it, at best it is wasted money, at worse, it can cause delayed ignition.

People think that Premium fuel has "more" energy, and yes, but so does diesel and we don't put diesel in a gas engine. What premium fuel is is high octane fuel. Octane ignites at a higher temperature/pressure than regular fuel, so it delays the ignition timing. If an engine is designed for high compression and you use regular fuel, than the fuel can ignite too soon. If the engine is designed for a lower pressure range, premium can delay the ignition point, causing timing issues.

Now, if you have a new engine with a computer that adjust timing, than it may be a non issue. That is why most modern cars can run on any fuel at the pump, but, just to make sure, see the owners manual.
