  1. 90 Octane Ethanol Free or 93 Octane 10% Ethanol for 1.8t?

    Volkswagen Passat B5 Discussion
    Hi all, The Shell gas station down the road has now a brand new 90 Ethanol free pump. Would you buy 90 ethanol free for your 1.8t or 93 with 10% ethanol? Unfortunately, I couldn't find a 93 ethanol free station in whole Atlanta. Almost all of them 87, with few 90. Key words: misfire...
  2. 89 Ethanol Free or 93 %10 Ethanol

    Volkswagen Passat B5 Discussion
    Hi all, I try my best to use ethanol free and the highest octane available as much as I can. The closest one with EF gas has only 89 octane EF. Would you go with 93 %10 ethanol or 89 EF? I have a 98, 1.8t.
  3. No Ethanol Premium = Hard Starts??

    B5 Garage
    Have an 01 AUG. Had this problem with my 02 AWP as well. When I put non-ethanol premium in my tank, it takes 2-4 cranks before the car starts when cold. When I switch back to ethanol, 1st crank. Any thoughts?
  4. Fuel additives to offset Ethanol water effects

    Volkswagen Passat B6 Discussion
    Anyone tried anything in this arena? I always run premium but my non-VW mechanic says it'll make the water mix better w the gas and burn off without staying in the tank. Any thoughts? I'm sure VW does not recommend additives but also may not have taken today's Ethanol usage into account. Thanks

    Hi! I"m new here! I'm from Brazil! I have a Passat 1.8 20v ADR engine 1998/1999. I convert the engine for use 100% ethanol! For ethanol, need a fuel injector with 35% more flow rate, and i have a fuel injector with 50% more flow. I use the ECM2001 for edit the ECU file, but the drive...

  7. Fresh exhaust smells like ethanol?

    Volkswagen Passat B5 Discussion
    Hey all, I noticed my oil was pretty low, probably because it squirted out of the breather hose assembly that's missing. Anyways, I also saw some sludge stuck to the inside of the metal when opening the oil cap. So I added about 1 and a half quarts with some seafoam. What I noticed is that the...
  8. Ethanol Passat?

    B5 Garage
    So, has anyone ever done an ethanol conversion on their Passat?
  9. Is Ethanol the culprit?

    Volkswagen Passat B5 Discussion
    So....talked with Bullit62 about this. Last month....exhaust tailpipe was clean as a whistle. Took a look at it the other day and this is what I see (sorry..HTC pic): It's actually blacker than what it looks like in that pic too....looks like diesel, but it's not a diesel. Jon and another...
  10. how do ethanol blend fuels influence fuel trims?

    Volkswagen Passat B5 Discussion
    So after buying a brand new cone filter, I've almost got my long term trims dialed in with this GT28 program. Both were within 1-2% +/- However, yesterday the trims went back to -5% and as low as -7%. The only difference that I can think of is that maybe filling up with normal old 91 octane did...
  11. Fuel Question: Petro mixed w/ Ethanol????

    Volkswagen Passat B5 Discussion
    I've noticed a few gas stations offer a 93 octane fuel mixed w/ 15% ethanol. Some cars are factory ready to except ethanol fuel like most newer GM's ; But I don't believe our 2001 B5.5 V6's are set up for ethanol. Can running fuel mixed w/ ethanol harm our fuel system, or our engine...
  12. Ethanol

    Volkswagen Passat B5 Discussion
    Rusty recently posted about experimenting with ethanol. Personally I would love to start using/mixing E85 into my gas because I hate supporting Middle East Oil. From his post it seems like the ECU can easily adjust fuel trims on a certain mix... but what im more worried about is the corrosive...
  13. Ethanol: The cure for independence from foreign oil, or panacea?

    The Black Hole
    I'll let the article speak for itself. I find some of the data intriguing.
  14. Ethanol experiments

    B5 Information-Base
    So I posted some thoughts about how the ECU would respond to running on ethanol a while back. Well, I acquired some E98 (not so easy in California) to do some experiments that I'd like to share. I added some to the tank, measured adaptation and did some test runs. This is on my 2001 AUG 1.8T...
  15. Running on ethanol

    Volkswagen Passat B5 Discussion
    So there are a couple of guys around here that want to start a co-op ethanol gas station (hey this is Santa Cruz... ;) ) They claimed that most cars can run maybe not quite E85 but a large fraction of ethanol in the fuel without problems. This made me curious so I started checking it out. At...
  16. Ethanol (alchohol) problems with fuel pumps on European vehicles?

    Anything Auto
    A buddy of mine has a 2000 VW Jetta 2.0L and he has gone through a bunch of fuel pumps and fuel pump relays over the last few weeks. Apparently, they keep burning out and there is no major problems with the vehicle. He called me today to tell me that apparently this is a major problem with...
  17. Ethanol In Passat?

    B5 Garage
    Hi all, has anyone ever used ethanol (E85) in thier Passat? VW's are not listed on the E85 ethanol web site but the site rants on and on about what high octane ethanol has comapred to regular gasoline.
  18. MTBE to Ethanol in our gas (certian states) quick question.

    Anything Auto
    Did anyone notice a change in gas mileage ever since they had to change from MTBE (i think thats what it was) to Ethanol additives? I have had a few friends say that their mileage got worse while others say there has been no change. I could almost swear that my miles per tank have dropped and...
  19. 10% Ethanol in Gas...Will it do any damage?

    Volkswagen Passat B5 Discussion
    On my recent pump, I saw a label that said the gas contains 10% Ethanol. So far, I didn't see any difference yet, but I would like to hear some comments or experience. Will it do any damage to the Turbo? Thanks!!!
  20. is sunoco 92 or 94 gas with up to 10% ethanol (alkohol) good

    Volkswagen Passat B5 Discussion
    is sunoco 92 or 94 gas with up to 10% ethanol (alkohol) good for our cars??? .....I heard that ethanol is no so good for euro motors. Also the cars running on fuel containing ethanol tend to eat up more gas (up to 20%) Is it true? I try to stay away from gas that contains ethanol (sunoco) so I...
