Freshest diesel in San Felipe.

brewer - 12-22-2012 at 11:07 AM

Which Pemex goes through the most diesel? In order to get the freshest fuel.

Udo - 12-22-2012 at 11:45 AM

The freshest diesel comes from the pump you are looking at when you need it.

I know which stations are the rip-off artists here in Baja, but had to buy gas from them anyway, because I was running out.
Surprising how a crooked pump can put in 72 liters into a 64 liter tank.

Bob and Susan - 12-22-2012 at 12:21 PM

why would anyone want the "freshest" diesel...think how the junk on the bottom of the delivery tank is all mixed up in the fuel

i think i would want diesel thats "settled"

and for udo..."prove it"...
i dont think you know what you are getting

liters throws me off too and i check all the time

remember you can fill the tank fuller in baja because they have different pump handels than in california...smog stuff

Look for the stations the truckers use, they know the stations you can trust and remember to run on the top half of you tank and not the bottom half.

brewer - 12-22-2012 at 04:20 PM

That's what I mean, the station the truckers use. Anyone observed that in San Felipe.

I'm sure once the fuel is pumped into the underground tanks, it starts settling. I just want fuel that constantly delivered. Rather that fuel that's been sitting and collecting condensation.

Its best to find/use a high volume station and the day after their tanks get filled are the best...PS,, to brewer..used to know a guy with that name and he made some fine homemade beer...K&T:cool:

I don't know about truckers but the mine buses use the station about half way between town and El Dorado, I have used it for fuel as have my neighbor and neither of us have had trouble, ?yet?

I am going to throw some thing out there about diesel in

San Felipe

number of years ago, the Premix in San felipe didnt sell diesel

I had to go to the harbor and get it ( no not on the docks)

but at the fuel depot at the marine that sold to the fishing boats and they have drive up pumps, and if I remember back then was not opened on sundays

Memorial Day weekend (OTL Over-the-Line games) San Felipe 1978(or 77?), the town ran out of gasoline on Monday when everyone tried to go home, and the town was crowded with American tourists!

Both stations then were fed from the same tank on the hill.

Remembering my dad once needed fuel, south of Santa Rosalia (in 1966) so bought AvGas at the Santa Rosalia/San Lucas airport (now a military base)...

I went to the AvGas building near the old dirt runway (by today's police station) and purchased enough airplane gasoline to get us to Calexico... and I "flew" out of town! At the border, there was no line... and the inspector wondered where the returning crowds were they had been expecting! We passed two Pemex tankers rushing southbound... and I told him they all would be about an hour or two behind us! :lol::light::cool:

Stop the gas/diesel superstitions. Buy your fuel and get on with your life.

Pumps go out of calibration -- sometimes but not often.

Fresh Diesel? I wouldn't worry about condensation. Water and fuel separates and the water sinks to the bottom of the Underground Storage Tank (UST). The fuel being dispensed into your gas tank is not pumped off the bottom of the UST.

Many statements above are total malarkey. Does anyone have any real experience and evidence to support these claims?

Hola,,Yes ,when I was a young lad was a district soop for USA gas stations,,Then worked at many Service stations as a mechanic..I NOW repair,Service,consult, Boats & Yachts.. and Fuels are A big part of IT !!!!!!!! Thats why in my post I said its better the next day after the tanks gets filled up and stired up the bottom muck..I would RnR the pump filters right after the tanker pulled away and the change the next morn again!! K&T

Ateo - 12-22-2012 at 07:38 PM

Keep in mind, there are tons of gas stations all over the world. They have this fueling system stuff dialed in. Failure to do so would put you out of business.

For the most part, a modern UST system is very reliable.

A pump can go out of calibration +/- from time to time, but not often.

Who complains when the meter gives you 1.1 gallons when you only pay for 1.0?

If a pump is unuaslly slow and weak..go to another station/port if possible !! K&T:cool:

Thanks for the response. USA Gas is really making their presence known lately in SoCal, being involved with the ARCO/BP/Tesoro deal.

In my experience there are rarely issues with contamination of fuel. Usually there are filters on the Turbines that pump the fuel and filters under the dispenser. Some filters can even restrict the flow of gas if water is detected.

captkw - 12-22-2012 at 08:07 PM

I cant say about today but I know in the70s & 80's chevron was the best wth their tanks and moniters and inspections... Being the curious kind would ask the techs alot questions..I know that since 84 tanks are two walled and depending on where/what area are a lot of regs in the USA...I can say with conviction the gas in baja is a far cry from what it was 25 yrs ago !!....K&T:cool:

This is a very astute suggestion. One of the potentially worst times to fill-up is during - or just after - a delivery, as everything in the tank is indeed stirred-up.

And, as noted, it's right after a delivery that dispenser filters need to be replaced, as they get clogged up. One "symptom" of a filter being clogged is slow delivery of the product. While there could be other reasons for slow delivery, this is something to be mindful of.

Regarding condensation and water in the tank.... the water in the tank isn't usually from condensation, it's usually from having leaked in through the fill-pipe. Mostly, right after it rains. That's why even today in the USA, you'll see stations that cover up the fill-pipe area when it's raining. It's also one of the reasons why the fill-areas are raised slightly in the station's parking lot - to keep water from collecting at or near the fill-pipe.

As far as the fuel pickup inside the storage tank, it's usually about 2-3" above the bottom... just enough for a small amount of water to not be too much of a concern - but if there's a lot of water, it's going to get pumped to the dispenser up above.

I have specific experience over a 20 year period in the handling of motor fuels, including many gas station (and wholesale fuel) locations with underground storage tanks.

Perhaps that was anything installed after '84, as single-walled tanks were in existence for quite some time afterwards. Our Norwalk, CA station in '98 still had single-wall tanks. ;)

Tanks

captkw - 12-22-2012 at 08:37 PM

I would guess pre 84 tanks are grandfathererd in..The top's around the fill pipe is called spill bucket and is designed to catch any spill when filling...But if its filled with rainwater would not work too well !!! I'm just glad they got ride mtbe gas..but this ethanol is killing motors with water and phase seperation.......K&T

Very good analysis. Yes, condensation in a UST is rare and water intrusion is mostly from those darn spill buckets (attached to the drop tube/fill tube) which get filled with water during rains. I always suggest floor mats or a sumpguard to cover the fill sump.

The Veeder Root should pick up anything over 1" (actually picks up smaller measurements) of water on the bottom of the tank if properly programmed.

Single walled tanks? Still a few out there. I inspect 7 sites in SoCal with single walled tanks and a few with single walled piping. They are required to run continuous statistical leak detection (CSLD ). Must pass a .2 gallon per hour leak test and .1 GPH annual test.

We need to meet up sometime BajaNomad and talk gas! Ha ha.

Ateo - 12-22-2012 at 08:54 PM

And just to scare everyone more.........

Things I've seen dropped into the drop tube of a UST:

Flashlight, a full set of keys, and a Master Lock. They are sitting on the bottom of the tank in Newport Beach, East LA, and San Diego.

I'm aware of additional similar situations, as well as some that are, unfortunately, far worse.

Ouch. I'm interested. Used Oil? Grenades? Leaves? Towels? Knowing may help me better understand my customers. =)

The old 7-Yeven in SF was famous for doing just that. I used to deal there until my 19 liter fuel can held 22 liters.:O I dealt there cuz I saw all the police cars, fire trucks and military getting their fuel there. No wonder governments go broke.:lol:
As for fresh diesel in SF, all the Pemex stations get deliveries on an almost daily basis. I guess it depends on how fresh the stuff is at the distribution center propr to those daily deliveries.
