May 23, 2014 Has your Yucatecan car been running a little pooch-ey this past month? Magna gasoline has caused problems for many Merida cars this past month, as over 2,000 PROFECO complaints have been filed over Magna ruining fuel pumps (recent Milenio report) and over 700 local Toyotas affected.
Our mechanic-friend Eduardo Perez (Mechanico y Llantas Itzimna 999 144 41 23 ) describes having to replace 23 fuel pumps over just a 2½ week span in late-April to early-May, as they seized up from brown gunk.
Note: PEMEX Yucatecan gasoline likely comes from Mexican refineries, while Norteños get their PEMEX gas from Texas & Louisana refineries => not necessarily the same product.
If you doubt the contamination, maybe a few fotos could help:
One tried and true method that ordinary folk can use to check out gasoline is to buy a little and store it in a somewhat transparent container.
I bought 2 liters on about April 29’th, and let it sit in this clean container for just 2 weeks.
a nasty brown thick sticky residue separated out at the bottom.
Imagine this in your fuel tank.
Imagine this brown sticky stuff in your fuel pump…
What’s a car owner to do?
… this latest problem of sticky brown gunk separating-out and damaging our fuel pumps, is just the latest round of PEMEX gasoline quality issues.

… If you want to complain formally – send PROFECO an email at ~ firstname.lastname@example.org ~ or ~ email@example.com ~ .. or Contact their FB inbox ” Consumidor Inteligente ” .
Some gringos tell us to add “alcohol” to “clean out your tank”, but alcohols DO NOT dissolve sticky brown gunk (I tried) – and alcohol simply takes that watery-heavily-sedimented-layer that sits in the bottom of your tank for years (like in the coke bottle) – and SWEEPS it up into the fuel – dumping 2 or 3 years of sediment into your fuel filter and injectors in one shot. …
Better solutions: BG products are the best (but not available here), Chevron Techron products like their “Fuel System Cleaner” or “Injector Cleaner” work excellently and were the first fuel additives approved by Mercedes & BMW. Lucas cleaner (shown below) also works well in our experience. The additives sold by PEMEX have not worked well in our experience.
