2 Stroke oil and Ethanol blended gasoline.

[dingbat]

Blanket statements about E0 or E10 can't be made. According to Hemmings - https://blog.hemmings.com/index.php/...u-might-think/ - only 7 states require ethanol blended gas and Maine has banned ethanol blended fuels.

This map is very misleading because it only reflects State mandates. There are a lot of jurisdictions (most large urban areas) within the States where E-10 is a federal mandate, not State regulations.

It shows Maryland as a non-E10 location, but try finding anything but E-10 anywhere but a few select locations outside the metro areas

CARB should know - http://www.arb.ca.gov/fuels/gasoline/faq.htm

I think the Hemmings article is correct. According to CARB, it's zero ethanol required in Ca. gas, however a percentage of oxygenation is required for winter blends. That's where the since eliminated carcinogenic MTBE came from to be replaced by ethanol.

That is not correct. We have so called E10 fuels year round. Our "summer blend" is actually more expensive than our fuel that is supplied during the winter.

I'm looking for a fence post. LOL

I have a 40 year old mercury v6 outboard and a 40 year old snowmobile. I have run them on E10 for years. I use the el cheapo oil, not the synthetic stuff. I figure the oil that was on the market when these things were designed was nothing fancy like what we have now. Been doing it for years, no problems. I tried changing from premium without ethanol to regular with ethanol. No changes in performance, idle quality, temperature, nothing.

Wimusky - Why the hell would I use premium? its not knocking.

Re Ethanol and oil - "But how do we get two-stroke oil to dissolve in ethanol? It won’t. At least cheap petroleum oil won’t do it. But expensive synthetic oil will."

[h=3]"A high-quality fuel is important. Most stock machines call for a 91-octane non-ethanol fuel to maintain the integrity of that motor. "

And the NMMA - [FONT=&quot]Nicole Vasilaros, the NMMA’s director of federal and legal affairs. “Consumers remain at high risk. We have serious, well-documented and data-driven concerns with the safety of high ethanol fuel blends which have been proven to cause damage to marine engines.

So. As I understand, its the absorbtion of water in the ethanol blended fuel that refuses to allow the oil to blend.

I don't know how many of you are running pre-mixed fuel, and how many have to do that with ethanol blended fuels.
SOOOO. If you are, and if it works (pre-blended) then let me know.. I'll save myself some cash on the full-synthetic stuff. My experience is with snow-machines, and most of that is anecdotal.[/FONT]

Why do you want the oil to dissolve if it does that your oil is garbage. You want the oil to mix with the fuel you need the oil to to NOT dissolve. Your fuel mix is a suspension if it dissolves there will be nothing left of it. I GUARANTEE you I have 6 gallons of of E-10 mixed 50-1 with regular oil and don't have a problem. E-10 is not considered a high ethanol blend. You really need to learn how that mix works.

The higher the octane, the harder that compressed fuel load is to ignite. Higher octane does not create more power unless your engine has a knock sensor and the engine management system adjusts spark timing automatically should it detect knocking. Then and only then does using premium fuel have value and a bit more power. As was pointed out, if the engine doesn't REQUIRE high octane fuel, it is a waste of money using it. As for two stroke oil not mixing with E-10, that is hogwash. By the time you leave the fuel dock or gas station that oil (regular or synthetic, cheap or spendy) is fully mixed.

Personally have 0 issues using premium 95-97 higher octane E fuels over lower ones, find faster throttle response, fuel last longer and combustion chamber forms less carbon build up. It's money well invested. OTOH, it's not same boating all day with say 4 gallons than doing same with 20 or more gallons, worse in frequent outings, costs issues.

Happy Boating

In theory, higher octane would actually give you slower throttle response if anything. Probably not even measurable since BTU content should be identical.

At least down here local minimum E8/90 octane is crap fuel. It's proven that yields less mileage per tank than higher octane same E8 premium fuels. Paying a slight bit more for better performance, engine cleanliness and better milage on my OB's and car it's money well spent for me.

What are they using as an octane booster that increase the BTU of the fuel?

 

[Schtoopid]

Thanks guys. That's the information I needed.
And I'm in BC. So everything has ethanol. Damn hippies hate my 40hp smoker.


Regarding high octane fuel, IF you advance the timing more, you can get more power from highost octane fuels. But with no other changes you'll see no benefit with premium fuel over regular.

If carb/timing synch is spot on, no need to advance timing as there's 0 piston knocking. Buy the fuel you want to pay for if thinking premium fuels are throwing money through the drain.

To get the most out of your motor advance the timing until it starts pinging, then back it down a tad......

I think the real problem comes when the yahoos down at the hardware store tell you the synthetics work better so you need less oil in the mixture ratio. I inherted a dirt bike from my brother as a result of that garbage.
