Your Opinion Of Your Vehicle's Performance Using Pemex Gasolines


Includes Magna and Premium Gasolines

Does your vehicle "ping" on Magna but not on Premium?

How is your gas mileage compared to US fuel?

How many miles at a time does your vehicle operate on Mexican gasoline?

Do you use an additive? If so, which one and what do you believe it does for the fuel, the vehicle?

Have you recently had a fuel filter clog on you? Do you believe you know which station was at fault?

Have you recently found (verified) water in your gasoline? If it was the fault of the station which one was it?

When and where was the last time you encountered a gasolinera "out of fuel"?

The above is meant to allow me to learn from other folks experiences. Thank you.

I always mention to people that while in Asuncion, one should maintain the tank with enough gas to get to Vizcaino because the station here is often out of gas. We use additives every couple weeks and if we have to go through a mountain pass to get to Sta.Rosalia or Ensenada...we use either half magna half premium or all premium...Juan's engine does ping without the premium going uphill.

We use Magna with our new Outback, and used it with our Tundra and no problems

How is your gas mileage compared to US fuel?

We get less milage in Baja then on a highway in the US, but we also drive differently

How many miles at a time does your vehicle operate on Mexican gasoline?

1200 +

Do you use an additive? If so, which one and what do you believe it does for the fuel, the vehicle?

no

Have you recently had a fuel filter clog on you? Do you believe you know which station was at fault?

More than a year ago and it was in the US on the way to Baja at an intersection and after about 120,000 on the Tundra---didn't blame anyone -- just happened.

Have you recently found (verified) water in your gasoline? If it was the fault of the station which one was it?

no

When and where was the last time you encountered a gasolinera "out of fuel"?

San Ignacio last year - they run out at times.

My 02 Yukon with 5.8l engine and 33 gal tank gets me a range of 600 miles on the highwy so I never have buy US gas when going back and forth. Around town I still get 15-16 mpg, so have no complaints about PEMEX.

My current vehicles never burn anything but Magna when we go to San Diego we fill up in Ensenada and on rare occasion we may have to add some in the U.S. but only enough to get back over the border. I have never had a problem with Filter's Water or Pinging If it it pings on Magna you need to adjust the timing.

In both my 04 Tacoma and the 04 GMC I use Magna and I can not tell the difference in performance. Some say the Mexican gas gives better mileage than CA because of no ethanol in it but I really can't say one way or the other since converting liters to gallons would take a calculator etc and I usually just do a quick divide by 4 and it comes close. Beside with the Mexican price being lower I'm happy.

Never, ever, had any problems with Pemex fuel. I understand that it's also a higher octane than what we buy here in California.

I get better mileage with Pemex than California gas for the simple reason that it is real gasoline and not diluted with ethanol which is counter productive to mileage.

Been getting about 10% better mileage on Pemex Premium than Chevron Premium (Calif CARB). No pinging, no additives (used to use toluene and/or xylene many years ago), and no recent fuel filter and/or water issues.

Never had any problems with Pemex gas. Drove F250's, Suburbans and now a Camry. As far as milage goes, hard to determine, since you seldom get the correct measure.

Ford Explorer runs just fine on Magna. Ford F250 with 460 runs fine on regular gas in US but pings badly on Magna on steep hills. Usually put premium in one tank and Magna in the other. Then run on the Magna tank and hit the switch for the premium tank just before the hill. After 50,000 Baja miles I know which hills need premium.

Milage is the same as in US.

Never have had a problem with water. Have only had one clogged fuel filter. ABout 15 years ago in San Quitin. As I was filling up I noticed the Pemex tanker on the other side of the station filling the underground tanks and thought to myself "Uh Oh". About an hour later I was changing the filter on the side of the road!

Compare to California gas?? Bad comparison


Wall Street Journal had a piece a while back
said there were over 250 different "formulations" for gas in the U.S.
Can you guess which state has the most "stuff" in the formula???

Anyway, the question I would like answered, is simple.
Where does Baja Norte get its gas?

I would bet it comes from Long Beach, since Pemex and the US have an exchange program to swap it back and forth across the entire border states, with priority to whichever country has the facilities close at hand.

My guess- it is US gas without all the California crapola

(And by the way- wonder why Cal gas is more expensive? Simple, it is all the stuff they have to add in)

The Jeep requires 87 octane, so we use Magna. I detect no difference in performance and no pinging. BUT............my check engine light comes on about every 8th tankful, and the code always points the finger at the fuel.

Yet it runs fine................
