I just read the recent Panorama (753) and there was a topic on the Tech Q&A on ethanol in fuel. Tony Callas recommended the regular use of Joe Gibbs Driven Injector Defender, particularly for infrequently used cars.

What do the rennlist experts recommend because my 993 is driven irregularly.

Thanks

I'd recommend finding Ethanol free gas.

Your vehicle was engineered for fuel blended with up to 10% ethanol. That said, ethanol has a shelf-life and over time ethanol blends can phase-separate if the vehicle just sits. So if you never drive it I recommend fuel without ethanol. If you drive it pretty regularly, it will run just fine with up to 10% ethanol blends.

I have been adding some (about an ounce per 10 gal) of Sta-Bil Marine formula to the tank every time I fill up with gas. The Marine formula is supposed to "neutralize" the potential problems that may be caused by ethanol.

Thank you tstafford, your search tool helped me find a local source of etoh free gas in my area I had no idea.

I want to get the benefits of this fuel asap, but my car is stored for the winter with the standard fuel containing etoh and marine stabilizer. With that in mind, would it make any sense to siphon out the bad stuff, use it in my DD and then fill via canisters with the good stuff? The rub is, I can't run it to burn off all the bad stuff already in the system beyond the tank.

Also, would I need to add stabilizer to the etoh free fuel?

Is this overkill?

tstafford

If it has the stabilizer in it, I’d leave it be. And once you start using the non-etho gas, you’re good to go w/o any additive IMHO.

JasonAndreas

No, it would not make sense. Just leave it and don't worry about it.

Thanks for all responses. Getting ethanol free gas resolves the issue at the root for me, particularly with the occasional use.

Paolo1

Thx. I see from your sig you live in the USVI where these problems probably do not even exist!

Have anyone actually had any fuelproblems after a six month winter lay up in h heated garage?

mine is always stored seven months each winter with the standard 10% ethanol fuel or whatever the filling station offered last time and it always start as if I drove it yesterday!

abiazis

Never an issue for me when I stored the car for several years..

JasonAndreas

I think we have it down here too. But I have a hundred gallons or so of E10 sitting in cars that are (now) parked for winters in the berkshires of New England. Where we've been using ethanol since the early 2000s because of MTBE leaks that were detected in the groundwater.

Cactus

Likely no. I used to get caught up in the hype early on into ownership. I use an ounce of Star Tron ethanol treatment at each fill up and thats it. If it sits 5 days or 5 months it starts and runs the same.

Sta-Bil Marine per Steve W. and company instructions, should be added to a near-empty tank, prior to fill up.
Ethanol in fuel is problematic in smaller and older engines like yard equipment, where carburetors and older rubber are negatively affected.
The ethanol "issue:largely revolves around the Department of Agriculture and the corn-sucking lobbies that impact decision making,
