The vette has been sitting for 3 years. I have added stabilizer each year, any thoughts if the stabilizer is working on the seccond gas tank.

Thanks

Curious myself if stabilizer needs to be added each year.
But, the thing I would say, even though you will probably say you don't want to hear it; either drive or sell the car! 3 years!!?? Why?
And are you asking because you want to sell it, drive it, or store it more?

Drive it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'd say your best bet is to put the stabilizer at the gas pump when the tank is near empty. That will make sure it gets distributed to both tanks. then drive home and park it.

But if the car has been sitting for three years with the same gas in it, I doubt the stabilizer was distributed to the passenger side tank - it really needs to be put in when the tank is near empty and then fill with gas to distribute the stabilizer.

I'd take the car for a long drive, burn out the old gas, then put in some Techron and if you're not going to drive it for a while, some fresh Sta-Bil.

You definitely should get that old gas out of there as soon as possible. Especially if it has ethanol in it. You may just gum up the works leading to major expense.

"Some is good, more is better" doesn't work for fuel stabilizer. Besides reducing octane the ethanol will separate from the gas at some point and make a mess. As previously stated, run it, use it up ASAP. If you ever find the need to leave a vehicle a long time with a full tank I would fill it with ethanol free marine gas and add stabilizer to that. Add Techron, it's magic!

There is no way for the added stabilizer to effectively make it to the passenger tank unless the tanks were near empty when stabilizer was added and the tanks filled. There is some transfer when the engine is run long enough to lower the passenger tank, then the engine shut off, and the tanks equalize again. This will be relatively minor transfer though.

If you added sufficient stabilizer to begin with, adding more will not really help either. If the gas continues to degrade, it is time to replace the gas.

My brother bought a new 2004 convertible, put 534 miles on it filled the tank & did not drive the car again until 2014. I put in a new battery, changed the oil, & hard to believe but the gas/pre ethanol was good, he drove it all summer with no issues.

Lucky so far. He could still have issues down the road.
