Default Holiday Gas And L67 *Fallow Up*

Everyone tells me that Holiday'* Blue Planet gasoline in hard on cars because of high amounts of ethonal used in it. I've heard of injectors getting clogged and big drops in performance due to gummed up fuel systems and carbon build up. However, those vehicles were pre 1990. I want to know if this holds true for the ser 2 L67. I want to sart using it because they are the only ones in town that sell 93 octane and they have a sweet car wash. Another one in town has 104 octane. So, do you think the Blue Planet gasoline is an adequate fuel for the L67?

Ethanol doesn't clog up anything really. It burns cleaner, and is made from corn.

ALL MN gas is required to have 10% i believe. There is that Holiday on ipava that seems to make my car run better... Plus it'* a nice, clean, new store, etc.

Ethanol doesn't "clog" anything....It tears up the injectors and kills them...And there'* something with GM cars and Holiday and Super America/Speedway fuels that chews the hell out of the injectors......I've seen lots of GM cars and trucks that have had bad injectors that was usually contributed to fuel quality....Once in a while isn't bad...but 91 is plenty sufficient for our */C'd motors. I on'y use Kwik Trip and Sinclair fuel in my truck and Bonne.....Because I've never haerd anything bad about them.

I think you would be hard pressed to find information that would contribute early injector failure to the use of ethanol blended fuels. Ethanol, although it has a lower energy release than gasoline, does not have any side effects in newer engines. The only down side of ethanol was that it would eat away at some older gasket and o-ring materials, but that is not an issue on anything 1970+ or anything that has had fuel system gaskets/o-rings replaced recently as newer materials are used. In newer engines, it will actually work at keeping the fuel system and pistons/valves/injectors cleaner longer than just using straight gasoline will.

Fuel quality has nothing to do with the prescense of ethanol. Ethanol by itself is 100 times cleaner than gasoline (wrt contaminants in the fuel itself). By far the dirtiest part of an ethanol blended fuel is the gasoline. Fuel quality does have a very significant effect on injector life, but by no means can you blame fuel quality on the basis that if it has ethanol in it, it is a poor quality fuel.

My B'ville runs great on Sunoco gas which in NY is a 10% blend. I have found that the Tops brand gas doesn't yeild great mileage and have since stayed away from it. The quality of the gas definitely depends on the chain (sometimes just the station) that you get it from. If you've had a bad experience on ethanol blended fuels, I'd bet the experience was the fault of faulty management of the station that you purchased the fuel from and not the result of ethanol being in the fuel.

Here'* some links to a few sites that have some pretty good information.... Just google'd "Ethanol Blended Fuels"...
Ethanol - Blended Fuels: Questions and Answers - by CA-OEE
Ethanol and Engine Performance - by RFA
Ethanol and the Environment - by RFA
Questions & Answers on Ethanol - by CA-RFA
Ethanol and Your Car - by NCGA
I particularly like this quote about half way down the page from the link above:
Quote:
MYTH: Most auto mechanics tell people not to use E-10 Unleaded.
FACT: A mechanic who says not to use E-10 Unleaded simply does not have correct information—particularly since every major automaker in the world approves the use of E-10 Unleaded. Unfortunately, there has been little information for mechanics on fuel formulation, so when a problem appears to be fuel related, some mechanics will immediately ask if E-10 Unleaded has been used. In some states, E-10 Unleaded advocates have offered a substantial reward to any customer who can document damage from E-10 Unleaded to his or her car—and so far, no one has ever collected.
I'll stop with those links as they already pretty much overlap in the information given. If you can find some reputable sources saying that ethanol destroys fuel injectors, then by all means post away.

Well, I just filled the tank with Holiday'* gas and it seems to run even better. It is 93 oct vs. 91 or 92 so that proly helps as well.

Does 1 to 2 points in octane really make that big of a difference?? Because I don't notice a difference between 89-93.....I only notice a performance gain when I run 110?

Kyle-

Good links and articles about ethanol.....I think maybe it wasn't ethanol causing the problems.....but maybe quality of fuel??? Or maybe GM just had some shitty injectors for a lil bit???I worked in a shop for a while and had seen lots of inj. jobs done...with SA'* and Holiday'* fuels being run as a primary fuel....So I dunno?

I stay away from Holiday'*. I've known 5 cars, all different makes that died when they filled up there.
I say find a station you like and stick to it.

Another thing to note is that if a car is run for a long time on crappy fuel, it will tend to get build up on the inside of the lines between the fuel filter and the injectors. Ethanol is a much better cleaner than even the detergents that they put in fuels nowadays. Ethanol will loosen this buildup and may cause it to get caught in the injector screens.

Over time, the ethanol will completely dissolve the buildup, but if you base your opinion of ethanol blended fuels on 1 or 2 tank fulls then switch back to non-blended, then you will have a poor opinion of ethanol. If you really want to give ethanol a chance, try it for a month or longer. You may experience some poor performance over the first 2-3 tank fulls, but after that, it'll be very nice.

Did I mention that you will never have problems with condensation buildup in your tank with ethanol! There really isn't a downside to using ethanol, unless you can notice the 2% difference in mileage or the fact that a 10% Ethanol blend carries 97% of the energy that 100% gasoline has... But both of those are very small differences and probably wouldn't be noticed by even a team of experts running experiments with different cars.

I do find sticking with one station works best.

Coincidentally Mankato also forces 89 to 87 prices...

Don't run a SC'd car on anything less then 91, especially in warmer months. ESPECIALLY Modded cars.
