Pemex needs to "grow up" about gasoline quality. Ever since USA gasoline was introduced in the form of 100% USA fuel for the northern Baja state (because Pemex lacked infrastructure to get fuel from the tank farm in Guaymas to Mexicali and Tijuana)...
And not being able to refine gasoline with a quality higher than Magna Sin, they were "encouraged" to import 100% USA refined premium. But the fuel PEMEX imports has MDA metal deactivator (electrolytic) and separate MBTE which is selectively added for sales in high emissions areas mostly based on seasonal weather quirks.
Presently USA gasoline stations are opening in northern Mexico and they are importing their own fuel. They are specifically not using Pemex refined base gasoline. Chevron Stations are touting TECHRON on their signage and diesel fuel sold in foreign flagged stations is guaranteed to be ULSD "Monikered Diesel UBA"
The only fuel I have found that actually helps that cursedly finicky engine in my toad is that which contains polyurea additive. Shell calls it "nitrogen additive" while Shell calls it Techron. I have been using straight BP gasoline for 5 months with no ill-effects and last week tested my theory by adding 16 ounces of Techron which did absolutely nothing. So with BP I do not need Techron. Yay!
With fuel prices at the moment being equal between California and Mexico I am not going to suffer a 10% loss of economy (forty US cents per gallon down the drain) by filling up inside California. Repeated fillups at one Chevron station then going straight to a BP station six or seven times has made my verification irrefutable. USA gasoline with alcohol sucks. Some folks may drive a WC Fields vehicle that thrives on alcohol. Mine doesn't.
