My wife's car has been sitting for a long time, due to her being ill. I wanted to syphon out about five gallons of old fuel and replace it with fresh fuel. The syphon hose would not reach the fuel.

Most newer cars have multiple obstructions to prevent this. Not sure how the best way is for the optima.. if the fuel pump is accessible from the back seat that might be the best way...

Drive it - then treat the empty tank with some Premium fuel and a half-quart bottle of Marvel Mystery Oil.
Then on the next fill-up, use a bottle of Techron Concentrate fuel line cleaner and a tank of mid-grade fuel.

That should fix your concerns..... which may not be anything to worry about anyways. My wife can't drive for a month. But that doesn't stop me from grabbing her keys and driving her vehicle twice a week back & forth to work.
I don't understand why you are seeing that vehicle sit for a long spell and not drive it once in a while?

How long has the gas been sitting? I bet the gas will be OK still. You can always add more fresh gas, or I wonder if there is a chemical treatment. But I think even if the gas sat for a year or more it would still run.

The reason it sits, is my wife can not drive do to her health issues. She has just came out of the hospital for the second time. We have three vehicles that are street legal. My 14 year old four legged son only rides in the back of our four door Jeep. He is not long for this world, and I need to have him comfortable when we travel anywhere. He does not do well in the Optima nor our pickup. his hind legs do not work very well, and he has many other old age issues. I can not put him down right now, because my wife could not handle it in her present condition. So, when we go anywhere we have to take our dog who can only ride in our Jeep. So the truck and the Kia sit. Our 2019 Kia just turned 3,011 miles. Our 2012 pickup has a little over 30,000 miles The Kia has been sitting for near one year. It still starts, and I did take it to the gas station today and filled it up with 92 octane fuel. It was near half tank.
Due to our dog being incontinent and senile he rides with us. We have diapers for him. If my wife could handle it, I would have put our dog down weeks ago, but she is very fragile physically and emotionally at this time. So I pray that our dog hangs on a little longer until my wife can handle it.
Things are not going well here. I have told you way more than I really wanted to, but that is why the Kia sits.

Sorry to hear of that - that's great you're strong for everyone.

If storing any engine, here's a very cost effective tool to use ($20 treats 160 gls):

Thanks, I will give it a try.

Use this it works great. Use Sta-Bil Fuel Stabilizer in any gasoline-powered vehicle or equipment you plan to store for 30-days or longer. It keeps the fuel fresh for up to 12 months during storage, eliminating the need to drain your tank. Works effectively in all gasoline blends, including Ethanol-blended fuel, up to E-85.

Thanks

Don't get me wrong Stabil is great but not near as cost-effective as Startron, which is just as if not more product effective in my experience.

I should have mentioned one does not pour the whole bottle in, far, far less which makes it far cheaper than any other product out there.

Here is the 'cost effective' math.

So there is a diesel version (basically more concentrated than the gas version) that treats 1024 gallons of fuel. Its costs $33.02 on Amazon, with my taxes $35.74. The container has 946ml. When I fill up my 26 gal tank, just after the yellow light, it takes about 20 gals (Once the first tankful is treated with say a Whole ounce we only want to treat what we're adding in, right?). Per the instructions the amount needed to treat 20 gals is 18.5ml. Dividing that into 946 gets us 51+ tanks of treatment. So $35.74 divided by 51 is $0.70 per fill up!! (and the stuff works as advertised!). Beats the heck out of any other product out there!

Company website: Florida Payday Loans | Cash Advance In FL | Express Cash (has a lot of cool nerd info on decarbonizing, ect.)

In case some are worried about adding a 'diesel' fuel treatment to a gasoline engine (i've been doing this for years on mowers, trimmers, atvs, bmw, 5 toyotas and a kia) from the back of the bottle:

• Super Concentrated Diesel Formula 931XX is economical to use in large applications; safe for use in all engines and fuels, including heating oil.

It is meant to be used continuously, at every fill. Doesn't have to be and doesn't hurt if you stop, sometimes I'm in a hurry and skip a tankful. But I aim to include it every time.

It will make a noticeable difference in the sparkplugs after a few tankfuls, pull one before and after to check them out. It is an enzyme based alcohol fuel treatment that manages to allow gasoline to burn just a bit hotter causing the decarbonization. My quads start up on cold days without even using the choke! Mowers and trimmers start in one pull too.

This one is just too cost effective and product effective to pass up. Luck all.
