Crappy gas! 850 94

Driving home from Albuquerque yesterday I was getting low (light on) so pulled into A Belen Conoco.......within 5 minutes after leaving the station engine hesitation no power. Check engine light illuminated after another few minutes of driving. Limped on home as I was still able to do the speed limit with no problem (75). Driving with muted power today but no missing.....What should I do? Drain the tank, add some fuel treatment? I get the impression from the back of some of the products out there that alcohol can damage fuel injectors and catalytic converters. Arghghghg!

Haven't got around to opening the hood since the correlation of getting gas and the problem seems so obvious.

Argh!

Re: Crappy gas! 850 94

Before you do anything, get the codes checked.

It's also a good idea (as the others have suggested) to use a fuel system/injector cleaner regularly. I regularly used Chevron's Techron Fuel System Cleaner for a while (probably one of the best widely available fuel system cleaners). Then I switched to Redline's, now I use AMSOIL's. For fuel additives, Redline's is the most concentrated in detergent and ability to clean deposits (and most expensive). To give you an idea, Chevron's has 4% detergent/volume, AMSOIL's 32% and Redline's 34%. Anything stronger and you'll have to run it directly through the fuel rail bypassing the fuel pump (i.e. unplug the fuse for the fuel pump and attach the can directly to the fuel rail as opposed to pouring it into your gas tank). This stuff has about 40-45% detergent/volume. In any case, follow the directions. Leaving a fuel additive in your gas tank longer and in higher concentrations than engineered causes crazy *hit to happen in your car.

And because of the cleaning ability of the AMSOIL, Redline and other fuel additives, they can actually dislodge enough deposits that when they get burned up, they set off warning lights.

But once again, get the codes checked first.

Hi. New to site. Present Audi(s) owner. If you wish to put fuel additive in,I only use Techron. All European mfgs. approve as it doesn't harm anything while cleaning. :won't re-deposit particles on anything "downstream".

Hope this helps. Jeff

While it could be the gas, you may want to find out what code(s) the ECU is displaying.

While methanol is not the best for some rubber type compounds in most fuel systems, ethanol will not harm your fuel system. Not sure either would harm the injectors (some solvents can if they disolve the coatings on the em coil of the injector) or the catalytic converter. BUT, why the concern about alcohol???

I would check the codes, (and remedy those) - add some fuel additive such as Amsoil PI, fill the tank and drive.
