Who Sells The Best Gas?

I was wondering if anyone has any information on which company sells the best gas? Has anyone seen a comparison?

If the octane is high enough to not knock in your engine, whoever does a high volume will have the least water/dirt on a regular basis. Everybody has to meet the same Fed. standards. There probably isn't a best or a worst. personally, I buy the cheapest.

This question is comparable to "Who sells the best oil?".

There is no answer that all agree on.

Some people knock mom-n-pop places, but I recently heard a local repair shop owner say he's finding alcohol(excessive amts.) in the fuel distributed by the major fuel companies.

I run 93 octane in my MB and have recently experienced knocking. I'm beginning to suspect that super unleaded and unleaded in some cases are now one in the same.

With the price of fuel going higher, there's no telling what sort of "water down" tactics the oil companies are going to engage in.

You guys are probably right. I agree with your comments.

Have you ever thought of using Acetone to improve mileage?

My BMW tech in Ft. Lauderdale told me in 1990 to only run Amoco. It may just be superstition, but I have followed his advise religiously. After all, Amoco gas is interchangeable with Coleman lantern fuel, also refered to as 'White Gasoline'.

Two years ago the Amoco station by work was bought by a chain which sells Shell. I was lazy and continued to buy gas there. Within a month the check engine light came on and I had to replace the O2 sensor. (This was when I filled up every other day.)

It is also worth noting that when BP merged with Amoco, they stopped selling BP formulated gas in favor of Amoco.

Ha. In the third article it lists tests by manufacturer. Apparently the "Mercedes" Sable fared well....not so sure I want to be putting this stuff in my engine despite the very scientific testing.

A Sable is a Mercury, not a Mercedes.

Makes one wonder what else may be wrong with those articles.

Speedway caused my 300SEL to cut out for no reason. I switched to Shell and it was better. I went back to Speedway and caused more problems and I have not used their gas ever since. I only use Shell 93 or Sunoco's 93/94.

It's all about the additives, and how they clean & lubricate your system.

Heck, even Chevron doesn't make their own gasoline today. They just license their "recipe" for Techron and have it added at the regional distribution center where all the bulk gasoline waits to be delivered.

Also, you want to go to station that has high-turnover. Which hopefully, but not always, means that the station's pump filters are being changed regularly.

Lastly, stay away from a station that is receiving a load/dump of gasoline in the grade you want, for at least 24-hours.

Dumping the fuel causes all the sediment/crap on the bottom of the tanks to mix. Waiting 24-hours allow it all to settle-down again. It's just like dumping water into a pail full of water and mud on the bottom.

I am crazy so I tried the Acetone in my 500 SEL and It didn't make any difference I could see. I believe that if it helped some cars it was because acetone is a good cleaner and it cleaned the fuel system so the mileage went up. My 500 didn't need to be cleaned up so no difference. It didn't hurt anything as I could tell as the car still runs great.

If the station has a high turnover, it might be refilled every 24 hours... Now what?

It is not really that bad. Most tanks have very little 'crap' in them. There can be water in the bottom. The fuel pump pickup is usually placed high enough that the last dregs are never introduced into the pump in any case.

It has happened, but it is rare. I don't worry much about it.

Best Regards,
Jim
