What would you recommend?

I've got about a half tank of gas that's nine months old. In that time I've gone from storage to servicing and back a couple times and exercised the genset each month and both are running well on it.

My question is, would you fill the tank now with fresh and have a 50/50 mix or run the current gas down to 1/4 or so, and then fill up?

Just writing this, I don't know that it would be good to run below a 1/4 tank and I'm feeling it wouldn't make much difference either way. What do you think?

As always, you all are very helpful, and your responses are appreciated.


Bob

Bob,
Our boat sits for up to 6-7 months at a time in the winter months. I've done it that way for a few years now and, upon time for boating season, whatever fuel has sat in there for that duration, has always ran that 250HP 5.7L 350 just fine. It may be sitting with a 1/2 tank, 1/4 tank or, possibly even close to full for that duration. It's (the boat) never failed me yet.

Our gas coaches, when we had those types, might sit for up to 2-3 months between uses. And they never failed us either, upon entering in to another trip or vacation. I'm no chemist or, fuel composition specialist but, I'm kinda under the impression that fuel made today, is better than it was years ago. I remember when I was younger, (a few hundred decades ago) I could easily tell BAD FUEL when I smelled it.

But, I could smell the stuff in boat fuel tank after sitting for the duration mentioned above and, to me, it smells exactly like it did, the day I put it in there. So, if your situation was mine, I'd have no problem taking either route out. That is, I'd add enough fuel for to make it a full tank or, run it as is. Your engine's been running fine with what's in there so, I'd just about bet the farm it will keep on running fine with what's left, either as is or, with a 1/2 tank of additional new fuel inserted.
Scott

I have often been warned about the dangers of "Old Gas".

Several years ago an Old Man moved from his RV which was in a campground I was planning on visiting to a hospital and then Senior Residense (Assisted living). His rv sat, and Sat, and Sat, and Sat, and Sat, for years.. Batteries wer FLAT, i mean would not even take a charge, Converter not powerful enough to retract slides I teamed up with Office Worker and park maintenance man and while OW pressed the button (to release the brake) MM and I pushed and we got the slides in. Old HWH jacks needed help coming up as well but that's way easier.

Put a new chassis battery in and tha big 8.1 Liter Chevy ran like it was brand new while I drove th RV around the CG and into the storage spot the boss man picked out. What can I say.

For the O/P.. I'd just fill it up and add a can (Read the label for how much Sea Foam to add) I sat for 3 years and I added Sea foam when I parked, then addd some fresh gas as needed due to running Generator for monthly exercise and the odd Hurricane. (Matthew) and finally when I got the engine replaced (Long story posted elesewhere) well.. Ran like new. These 8.1's are darn near bullet proof. in fact that's about the only thing that will kill 'em.

Ethanol in fuel(most of ours in North america have it) can begin Phase Separation in as little as 30 days if un-treated.

PetroClear - Understanding the Dangers of Phase Separation in Ethanol Blends

Before storage always treat the fuel with a Ethanol 'killer' like Sea Foam, Stabil, etc. Because once the fuel Phase separates, it's too late to treat it and it must be drained or pumped out.

In nine months most likely you're fuel has separated if it was not treated, so I would consider pumping it out or risk future engine problems.
