What are your opinions on using gas that has been sitting around.? For those with built -in tanks, what has your experience been? Do you have any special procedures? Is it not a problem for you? Tell us if you have had any problems that are related to bad gas.

thanks.

How old is the gas ?
Was the gas treated with sta-bil ?

My hydrasports before i take her out of the water for winter, i fill her up (100 gallons) and treat the fuel with sta-bil.
Motor is a 200 hp ficht.
Been doing that since 1998. No problems.

I will put her back into the water around May time frame.

One more question: how full is the tank? (full is good).

Gas will start to brake down after three months. With sta-bil in it, it can last up to a year.

I've tried this with motorcycles... I've let gas sit for 6-8 months, and it hasn't mattered whether it has Sta-Bil or not. Runs about the same, but I still use Sta-Bil. After two years, I've gotten a little missing, and with 3 year old gas, there's quite a bit. Neither with Sta-Bil.

My mechanic for John Deere lawn tractors and the mechanic for our boat motors both say the same thing. Significant changes occur in the gas after as little as 30 days (less if the tank is half empty). Use Sta-bil all the time.

I just spent $200 on my 2HP Honda getting the carb fixed. Reason - forgot to run the gas out of the carb with the gas valve. Probably would have been ok if I had had Sta-bil in the gas. Those jets are so small on that motor that ANY varnish or gum plugs them up.

So, I keep a squirt bottle of Sta-bil on the boat and add it every time. Can't hurt, that's for sure.

wwbach -

We have a monthly housewaste hazardous waste clean-up in town that takes gas.

Also, you can run small amounts though your car or lawn mower. Add a couple of gallons when you fill up - mix the old with the new.

Jim, With regards to adding a couple of gallons to the car, any worries with running 50:1 in the car? I suppose not but thought I should ask.

I mix old gas with oil and put it in the tank of my truck. The Cummins doesnt care as long as it has oil for lube

Wow! Youb wrote "...mix old gas with oil and put it in the tank of my truck...the Cummins <diesel>??? doesn't care as long as it has oil for lube..." Did I read that right - you mix "gasoline" with diesel fuel for your Cummings diesel??!! Is that a good thing to do? I mean, I know the Cummings is TOUGH but...dang!! Now, on a sidenote, I have an old Acura Integra with a bunch of miles on it (runs great, still, the old work car/battlewagon), and I DO run old mixed/2 cycle oil gas through it regularly, no sweat...exhaust has a faint outboard smell to it, and it has the urge to pull a water skiier from time to time.

You might try PRI-G or the new Startron from Starbrite. I think they are both designed to improve old gas. Might check with Pri-G and see how old is old for there product to change it.

I have been running 50.1 in my old briggs powered lawn mower for years...That way I do not get the fuel mixed up...guess what the lawn mower does not smoke at all using the 50.1 and I have not changed the spark plug in 2 years.

First, a brief story...

Last April, I drove down to my Mom's house in FL for a visit. She's moving soon and wants me to take whatever it is I want from all the stuff she's been carting around since I joined the Marines twenty years ago.

Among this stuff is a 1965 USGI Coleman Multi-fuel lantern that my Dad acquired sometime during his 25 years the the Army...

We used it often on camping trips and the like when I was a kid. The last time I remember using it was when I was in 4th or 5th Grade. I'm 39 now.

Anyway, I bring this lantern home, and when I remove it from it's (orginal) carton, I notice it still has some gasoline in it. These lanterns would run on Gasoline, Diesel, White Gas, or Kerosene.

I dumped the gas, about a pint, into a jar and then burned it in my driveway. 30-some-odd years later, it's still flamable.

I don't know that I'd run it through an expensive fuel injection system, but it still burned.

I think you'd be suprised how long untreated gasoline will last.

My Whaler has a 125G tank. I regularly leave ~100 gallons in it with a can or two of SeaFoam to overwinter. Never had a fuel related problem.

Add some SeaFoam to it, and use it...

HOLD IS THAT GAS?
How long does it take :
from the time the oil is refined into gas?
How long is the gas stored in million gal.tanks before it is shipped?
how long is it sitting in your dealers storage tanks before you buy it?
What about all the marine fuel sitting in marina,s now in the northeast waiting for spring to be sold?
How old is your gas? we will probably never know the answer to that....I suspect older than we think.
