Fuel

Everywhere in town is out of ethanol free!!

I need fuel tomorrow. What do y’all think of 5 gallons or so of ethanol gas with mercury additives (which I use anyways). Regular, mid, or super?

2020 mercury pro xs 150 with 53 hours.

Regular is recommended, not really that big of issue. Put gas in it and go fishing.

regular gas and 1 ounce per gallon of B-12. Just as good as non-ethanol

No its not. If your running a newer 4 stoke I wouldn't sweat putting E-10 gas in it, now for the older 2 stokes I won't let them touch ethanol fuel

I only run regular gas, Yamalube Ring Free, and Lucas Oil Fuel Treatment and never have any trouble.

If you fish all year ethanol shouldn't really hurt you

I agree with Bradnitro175. If you burn it off real soon it shouldn't be a problem. It's not so much the ethanol that does damage but ethanol + time sitting in the tank and fuel system.

Thanks all

So much mis-information and old wives tales in this post.

I haven't used ethanol free since they mandated E-10. I've never had a problem... I always follow Mercury's recommendation of Quickare and Quickleen with each fill up... Ethanol free is just a money make for the gas station... Dan

just had to replace powerhead on 250 HPDI. have ALWAYS RUN RINGFREE, STABIL 360.Needless to say it's been an expensive adventure, leaving me paranoid. Now I drive 20 miles for ethanol free gas
hoping it will help avoid repeat. One more of these will probably put me on the bank with cane pole and bobber. By the way thought about repowering with 4 stroke but none available.

I run 89 ethanol in my 2014 250 SHO with Yamalube and have zero issues.

Fill us in.

Well, it's clear the fear of ethanol is over-hyped. It is ethanol SITTING that does the damage. If you run your motor consistently and often, ethanol doesn't really have a chance to do much damage. If you run ethanol with an ethanol "buster" fuel treatment there isn't much to worry about really. All the new fuel lines are not prone to ethanol degradation anymore, they fixed that issue. That's straight from one of the best Merc Mechanics in Texas. Now days, if you use an ethanol treatment and run your motor a lot, then ethanol isn't really a concern. Now, the HPDI's do struggle some with ethanol gas sitting in the tank/block and then being run hard out. They had the #2 cylinder in the big blocks blow sometimes. Others blew, but for some reason #2 blew more than most. Just did, that's why they came out with the series 2, to fix that issue. The smaller blocks like 175's didn't really struggle with this, the bigger the block, the more trouble they had - 250's and 300's. Still does happen, saw a guy yesterday at Fork who's HPDI popped. Don't really know why that was. Now, running 5 gallons of ethanol gas for a day of fishing ..... NO PROBLEM AT ALL, go fishing and have fun. Run that motor hard. Don't believe all the internet chatter about ethanol now days.

Thank you!
