Americans Crossing Border For Cheap Gas.

What about the quality of the Mexican fuel?
Hansen spoke with a variety of San Diego mechanics who have shops by the border and they said they haven't seen any unique problems from cars that get their gas from Mexico.

Cars that are built to be sold and driven in Mexico are designed for the junk fuel that is sold there. Cars designed and built for the American market are meant for 87-93 octane fuel with detergent.......they can tolerate Mexican fuel for short periods if they have knock sensors, but clearly are not designed for it.

After hearing that people are crossing the northern border into Canada to receive medical treatment because in America health care is too much of a luxury , this doesn't surprise me.

Actually no, this is completely untrue. An engine will destroy itself in seconds if it detonates and has no means of changing tune to save itself. SECONDS. How do I know? I've done it. More than once. Why? Because sometimes the only way to find the limit is to go past it.

Wish this reporter had lived south of the border running his vehicle for 6 years and paying the interior of the Republic price, not the border prices that are cheaper to compete with the U.S. (at least until now).
Many of you read my commentary for years about the quality of gas in Mexico. If you do go across the border make sure you fill up a full tank before going across.
However, if you have to go futher south, only use the Premium 92 octane UBA (Ultra Baja Azufre), ultra low sulfur. Still higher than U.S., but an improvement over many years ago. Only nice thing about sulfur was that I found the engine ran a bit cooler. By 2009, Pemex is expected to introduce a low sulfur version of their 87 octane gasoline known as Magna.
There really is a quality difference. My uncle and I would fix an inordinate number of fuel filters compared to what I knew of in the U.S. and injector issues were common. It opened me up to a whole new world about what I knew could go wrong with a motor vehicle.
My RX300 was quite happy to fill up at Chevron station when it came across the border for the first time in almost 3 years.

Holing a piston can easily happen in seconds, again, I've seen it (when you get the squish wrong on a two stroke, bad things happen very quickly.) The link here explains detonation exceptionally well and dispels quite a few myths I've seen posted here on CL about pinging and detonation.
