Touareg :: Is 90 Octane Fuel Ok On V8
Apr 25, 2005
Was wondering if there would be any negative effect on the performance (or engine) of my V8 Touareg if I start filling up with 90 Octane instead of the more expensive 93 Octane available locally in Puerto Rico. We only have 87, 90 and 93 Octane to choose from. There is a German warning label on the inside of the filler door that says something about 91 Octane. I don't read German, but I'm assuming that it means not to use anything lower than 91 Octane fuel.

Just filled up with Shell V-Power 91 Octane Fuel for the first time in my MKVI Golf 2.5
I know 91 isn't needed in this car but I like filling up with good fuel every once in a while.
After filling up my check engine light came on right away, also my engine wont allow me to go over 3k RPM.
Why did this happen and what can I do to fix it?

Just got a 2004 1.8T wagon, but it didn't have an owners manual. Do I need 91 octane? Is a VW dealer the only place for a spare key? Can you steer me to a catalog for bling (grille) and other mods?

I own a Lexus IS250 which on the gas cap says you must use high octane gas. My question is, do you REALLY have to use High octane everytime you gas up or can you safely use mid grade? Say every other time without damaging anything?

2006 ranger v6 3.0L mfi .. an I switch to 85 octane? it's not a flex fuel vehicle. would there be any problems doing this? I guess if they use it at high altitudes like Denver then there would not be any harm using it at sea level as long as the engine doesn't ping with predetonation.

I am looking at an 05 Corolla with the 2zzge. I am wondering if can run regular gas in a pinch with octane booster? Some areas where I travel only have regular fuel.

I just recently brought my 2006 subaru outback (v6) to the shop. The men, whom I've know and trust, told me there's too much carbon in the engine - it's got 80k on it - and that I should use Super the next two times I fill the tank. I went to an Irving station and put in Premium Octane. I only put in 3 gallons, and now the gas jerks upon pressing the gas. The check engine light came on, the SPORTS light is blinking fast and the CRUISE light is blinking as well. It sounds bad and when I put it in/out of park, I hear a little bit of grinding. Is this common for putting in new higher quality gas? Am I destroying something?? Should I not have put in premium?

04 V8 Touareg. The switch for both the fuel hatch and rear hatch dont work. They worked the other day. I checked all the fuses and everything looks good there. I had disassemble the right rear interior panel to remove the CD changer to get at the manual release lever for the fuel hatch.

My lid is "stuck" open. It looks like it is missing a part. Looking for a pic of the latch assembly or diagram if they get a chance?

Our recently purchased '04 V8 Touareg is increasingly sounding like a jet turbine engine upon start-up, and especially as winter approaches. We're told it is probably the DC-powered fuel pump. Any way to reduce the aural effect?

I remember reading very recently about someone who found a fix to the strong fuel odor on cold starts. I can't seem to find it anywhere. I think it mentioned something about a bad ignition coil or something.

My Audi has always been at about 2 gallons or so, and usually around 30 miles left on the range meter. The Touareg seems to come on much earlier, around when there is 80 miles left on the range meter. Is the reserve on the Touareg much larger than the standard 2 gallon reserve? Is the range meter accurate at 80 miles?

I was curious as to how ambitious a project this would be and if special tools are needed.

Using fuel additive with V10's in extremely cold weather? If so what are you using?

I notice that not only does the fuel pump primes when the drivers door is opened but also when the rear hatch opens.

About three weeks ago, I started smelling diesel fuel order every time I get off my car. The order gets stronger and stronger, I called the dealer service on Monday, the adviser told me bring the car there right the way. It took them more than two days to find out the cause of the fuel smelling; the fuel filter housing unit leaks the diesel! Today I was told it would take at least ten days to get the part in, and I was politely offered an Exploer as my loaner. The V10 was made on 04/04, delivered on June 3rd 04
I do hope this is the only one problem, not the beginning of the Pandra's box. Still, I don't feel that good for the time frame of the coming part and the difficulty of the trouble shooting.

Having trouble with the fuel level readings in their t-reg? When I fill mine up it shows as full but drops to 3/4 of a tank within 10 miles. Then it reads fine for about 300 or so miles and then drops to empty in about 20 or 30 miles. When I fill it back up it still has 6 or 7 gallons left. And yes, I am using 91 octane gas.

About a week ago I got the fuel cap light on a steep hill in San Francisco. Next fill up it looked like the cap might have been a little loose. Can't remember exactly. A few days after the first warning I got a solid check engine light. I have 110K miles. I've had the coil packs replaced twice and the check engine light flashed when that was the culprit.
I've driven the car 4-5 times about 5 miles and the light hasn't gone off on it's own. It is a real hassle to take it to the dealer and I don't have much time. So:
1. Will it clear itself of the issue goes away, or must it be cleared at the dealer?
2. Any other V8 04' had the same issue?

I have a 1989 GMC suburban V8 350 5.7l that will not start. I have replace the following fuel pump and sending unit, fuel pump relay, ECM computer brand new, new fuel filter. When I go to start it the fuel injectors dont spray fuel into the combustion chambers verified fuel injectors still work by bypassing them and they spray fuel. Fuse's are not blown. I have been told the oil pressure switch might be bad but I'm at my end of sanity on this.
Additional Details : Tried spraying fuel into the throttle body and still no fire, ignition module and ignition coil where replaced 15,000miles ago.

Today, my 1995 E150 suddenly started acting like it was running out of fuel Lucky for me, this happened close to both a parts store and my usual mechanic's shop. Unluckily for me, it happened on Saturday, and my shop can't get to it until Thursday. So here I am, hoping to do a fix in the meantime.
At first, it seemed that it must have been the fuel pump, because I couldn't hear it come on when I turned on the ignition. Then, a guy who said he was a mechanic told me he could hear the pump cycling, and that my problem was the fuel pressure regulator. So he managed to start the vehicle after a few tries, then it crapped out again. He did this twice. Then he went away.
I called every parts store in town, and none of them had a fuel pressure regulator for my vehicle, and the earliest any of them could get one was Monday. But I knew I was due for a fuel filter, and I'd changed filters on this vehicle before, so I got one of those and put it in. To my delight, the van started right up and idled beautifully. In fact, it ran beautifully for about 15 minutes, until I came to a slight rise, then it crapped out again. It still started up and idled smoothly, and even revved up smoothly, until it reached a high idle speed, at which point it crapped out. I did manage to limp into the parking lot of my shop - which, again, can't get to it until Thursday.
So my question is: does this sound like a fuel pressure regulator to you? If so, is that a job which somebody with a reasonable mechanical aptitude (i.e., at least good enough to change the fuel filter) should be able to feel safe doing? If the answer to those two is "yes" (or even if it's "no")....
