Fuel Question - Info Needed

[Cubacheski]

Curious what everyone uses in their Tige. Do you use regular no ethanol, premium no ethanol, do you add any fuel additives, Stabil in each tank.. etc etc.. Just curious what everyone puts in their boat to keep it running smooth. Thanks for your information.

I use the middle grade and try to add Marine Stabil to every tank or every other one.

I am guessing you are going to get lots of different answers.

Grab the popcorn, cause this topic will be good

Your engine is designed for 87 octane, so no need or advantage to run higher. If you fuel up on the water, most marinas have 89 oct in the tanks, so you are stuck paying more for less.

Your 08 fuel system should not suffer any ill effects due to ethanol blended fuels. Its nothing new and has been around for years. The only side effect of ethanol to be concerned with is water absorption and phase separation. During the normal boating season, this should not be a problem. When storing for the off season, adding some fuel stabilizer designed to fight the effects of ethanol should be all you need.

I dont think running a shot of additive in each tank will hurt anything, but its overkill IMO.

The 350 Merc in my boat needs nothing more than 87. I ran the same in my 496 Mag Merc motor.

87 and fuel stabilizer only when storing for the winter.

I run 87 octane and put stabilizer in the winter for storage.Use the blue marine fuel stabilizer . As mentioned above other gas additives while your using the boat are overkill.

I use regular 87 with 10% ethanol and add marine stabil on every fill up. In my job I can be sent on a business trip or stuff just happens in life and I like to have some protection in the fuel incase the boat sits for a month or two.

I too use 87 octane with 10% ethanol. I also add marine stabil with each fill up as we're not able to use our boat every weekend.

I guess I should have clarified 87 octane which is mid grade for us.

Thats right, CO has 85... don't use it. ECM's are programmed for 87 and any higher octane tends to leave soot on the transom from an incomplete burn, worse economy etc... IF you can find non-ethanol fuel USE IT!!!!!! Ethanol is garbage and has caused numerous fuel system problems in boats.

87 and sta-bil, at least towards the end of the season.

chpthril was right, get out the popcorn! 85 is just fine for use in your boat in Colorado. Since there is less oxygen up here, there is also less chance of knock and hence the reason we have 85 here in the first place.

[What she said]

I run premium, stabil in the winter, and one tank of B-12 in the spring. There are advantages to premium fuels!

1. Premium fuels have more additives (cleaners)
2. High octane will burn more efficient
3. Better fuel consumption (very little increase)
4. More power (very little)

I see it as money well spent, and other will not!

[Timmy!]

4. More power (very little)

Common myth. You will ONLY get more power if you increase the timing. If you are running EFI, it doesn't do that automatically. There is more energy content in lower octane fuel but higher octane allows you to run more timing which would potentially give you more horsepower. If you are in fact running more timing, you probably will get more power but I doubt you increased your timing. Don't believe me? Go research high octane fuels.
