Non Ethanol Gas (Boat)
- Thread starter skeeter2010
- Start date
You will not hurt the motors by running with old fuel. Use sea foam in tank. Maybe throw in 10-20 gallons fresh gas. Get it running. Fill with new fuel as soon as possible. I wouldnt even clean the carbs unless it runs like crap. Carbs will clean themselves with new gas and sea foam. Put in new fuel filter after tank has ran through old gas. If thing doesnt start then trouble shoot and go from there. Grew up around junk yard. I have never seen a carb get pulled from a car that sat. A little new gas and once they fire away they go. Just test the engine for a good amount of time before you leave dock, obviously.

I am gonna throw a few thing out there...and you all see if its a good idea then
SEAFOAM is for maintenance....not RESURECTIONS
I would not use it in a boat because of the high load the engine is under but for lawn equipment it will not harm it
Adding a fuel system treatment to 5 year old gas does not make it new gas -- it is still stale
Gasoline is a highly refined product brewed to a certain chemical composition with very specific characteristics, including, for example, volatility — a term used to describe how easily (and under what conditions) the gas vaporizes so it can be efficiently burned in your car’s engine. But the most highly volatile components in gasoline also tend to evaporate over time. As they do, the fuel’s volatility degrades
Condensation from heat cycling can form inside your vehicle’s gas tank and fuel lines, especially if the tank is not completely full.
Another problem is ethanol alcohol, which now comprises as much as 10 percent of all “gasoline” sold in this country. Alcohol likes to draw moisture out of the surrounding air. And water does not work too well as a fuel in an internal combustion engine.
These deposits and impurities can coat surfaces, clog up fuel lines and filters, as well the small orifices in a carburetor (jets) and the even smaller orifices in a modern car’s fuel injectors.
PS....Run an AD in Craigslist and sate that it's "free fuel...just come and get it". Be sure to sate that it's 2-3 year old fuel out of your boat.....that way they are informed ahead of time.
this is only a fraction of what it will do....good luck....and I see we will have a Darwin award contestant maybe...I hope its not a DONZI or COBALT....my bud races a triple motor DONZI with 500s and i make him parts sometimes...you want i should ask him what he thinks....ROTFLMAO

Well thanks there Tracker, you just explained what everyone in this thread already knew. We are not debating that fuel degrades over time. My specific question to you was : please explain how trying to start a 4 stroke motor on NON ETHANOL, possibly stale gas, will cause catastrophic engine failure. To the tune of a $30,000 overhaul bill as you suggested. I'm still waiting for an answer.
P.s. you should talk in complete sentences more often. YOu....aRE....muCh.....MoRE....CoMPrehenSible.......THAt WaY! Rolomolofolo.......

Try to get the boat started, I think you can, A four stroke on older fuel will run especially NON ethanol. My old car and truck have 3 4 maybe 5 year old gas station gas in them and I drive them around the block once a year, They run fine, a little hard to start, Your not going to blow the motor up in a four stroke, they just won't run proper, you'll know right away, A 2 stroke yes they will detonate and burn a hole in the piston. My thoughts. been working with two and four stroke engines for 27 years.

If this thing is in harbor get it fired up and then wait til MMSD does a sewer dump in beautiful Lake Mitch and join in...that way the fuel dump will just be a drop in the bucket along side what they get away dumping with every deep tunnel overflowing heavy rain in Milwaukee. While the DNR and EPA ignores all.

BILLIONS of gallons of raw crude naturally enter the oceans.....and billions of gallons of oil/gas runoff enters the "fresh" water through street drains. In Milwaukee it is combined with raw sewage as well.
Drop in the bucket....LOL.... get over yurself!....BILLIONS....LOL ...his fuel might dillute the chit that Milwaukee gets away with dumping!

Get over yurself, even if as much as you claim is getting into water. And a hundred gallons is a drop in the bucket. It still doesn't make it right.
Never said seafoam will ressurect old fuel. It will however help clean fuel system and revitalize some of the seals that may be dry. Old fuel is not going to destroy the motor. Just make it under perform. Just giving him some real world experience with old fuel.

Of course, and it was just sarcasm.....you serious guys keep giving professional advise....LOL...I say pump and dump in my nytro, she'll burn anything.

ok....how much do you think a 502 costs....short or long block...and not some rebuilt junkyard one either...now times 2....and having blown a lot of motors on carbed or efi and using seafoam and all that CRAP everyone suggests that doenst work and causes more damage...I have learnt....that ya don't sacrifice 3 months downtime....100s of hours of labor...and engine rebuilds....for the chance....that the gas might not have particles in it...the water problem is secondary...and it will wash by the piston rings and destroy the motors...dual in this case....obviously you have never tried to do this with a vehicle that sat or you would know....he doesn't know yet...that's why hes asking...heres the reason why it will damage the engine and no amount of any marvel mystery oil or peefoam will save it OR CLEAN THE CARBS OR ORIFICES OUT.....any engine guy knows this...its basic 101....the particle will glog...overheating wil occur....and knocking will begin...and seizure will follow....yes its a chance...an 80,000 dolla one....as I said...ALCOA,YOU MAKE THE CALL....LOL
Water is a polar molecule and has far stronger intermolecular forces than oil which mostly has Van der Waals interactions, but it has far smaller molecules than oil, so the molecules in water can move easily past each other without transferring much momentum between layers that are moving at different velocity - leading to relatively low viscosity at normal temperature and pressure.
Oil is a mixture of larger and longer molecules than water, they are linear and cyclic multi-carbon/hydrogen chains, so the molecules tend to get tangled up with each other - leading to a larger transfer of momentum between layers having different velocities, and thus to a higher viscosity.

any side bets....LOL....me says they blow if he runs em...
youse guys that use seafoam....you want I should tells ya sumtin' bout dat?

Did you even read my posts? The very first thing I said was check for water...and I never said anything about sea foam. Particles in the fuel are a non issue. Thats why they make fuel filters! A partical will cause overheating, knocking and seizure? I guess I've officially heard it all now!
I've been a mechanic for 22 years so yeah, I've started a vehical or 2 thats been sitting. Never blown one up, never seen one blow up, never heard of one blowing up....ever. Not from stale gas.

I Agree. Sea foam isn't going to resurrect an engine but it can clean up internal parts. If tanks half full then top off to bring old gas back to life. But then run the engines as much as possible to get rid of the gas. Also agree with snoluver. Do some tests first before dumping all the gas and where would you dump it??

That was funny. I can't even understand half of what he says most of the time
I think you've got something there!
I have noticed that you can always tell tracker's writin' vs. his quotations — the latter being perhaps even more distinctive than proper use of the forum's QUOTE feature:
Tracker's writin' is always in "steam of...thought....continuous...run-on....format" with.....randomly interspersed.....bursts of..."Morse code"[SUP]1[/SUP]...like.....this with...absolutely no....punctuation, whereas his quotations are typically well composed complete sentences, with proper spelling, grammar and punctuation!
[SUP]1 "Morse Code": Just a subset though, composed solely of "S (•••), H (••••), I (••) and T (―).
Maybe there's a hidden message there?
Er, correction… oddly enough never a "T", but maybe the numeral 5 (•••••) instead.[/SUP]

I'm not sure why I even engage with him? I guess I feel some kind of civic duty to try and provide factual rebuttals when he spews his nonsense. I try to ignore it usually, but it just keeps popping up everywhere. Like a swarm of black flies buzzing around your head. For the first time in something like 20 years of coming to this site, I'm actually thinking about hitting the "ignore" button.
