Gas Grades
I have recently bought a Toyota 4.71l SUV. Has anyone tried to run one on any of the lower octane grades with any success, or am I stuck with using
the premium grade?

What does the owners manuel say? It should give the octane requirement...
My '05 Tacoma with the 4.0 V-6 runs great on 87 octane regular here and Magna in Mexico... no pinging (pre-ignition/ dieseling) which (if happens) is
the reason for using a higher octane/ premium fuel.

magna vs premium
My Ford 460 V8 loves regular 87 Octane in the states-----hates Magnum in Mexico----ditto for my Isuzu Trooper 2.6 liter 4-banger. I always burn
premium in Mex. if I can get it. If not, I add octane booster, and that takes care of it.
I once burned a hole in a piston of my Ford 240 cc 6 cyl. while coming home from BOLA on Magnum-----that was not a fun experience. That was about 25
years ago, tho. Things may have improved by now.

I have a 2005 Tundra TRD with the 4.7 motor. I bought it for a tow vehicle and just returned to Loreto a couple of weeks ago from Florida with a new
boat in tow. A 9,200 mile roundtrip. I burned regular in the States and Magna in Mexico. The 4.7 runs great on 87 octane Magna and did fine on the
86 octane regular some places on US-10.

Barry... 25 years ago may have been NOVA (remember that stuff?)... ?? That tested to about 79 octane and even my Subaru would ping on IT! Octane
booster or retarding the timing was needed.
Nova was dropped and Magna became the 'regular unleaded'... Previously it was the highest octane in Mexico. Now, there is Pemex Premium...

gas is gas...
marketing and urban myths make one gas better than another.
newer cars and trucks use computers to monitor gas usage and flow.
there is no need for higher grade gas unless you are operating an older car (pre 1980) or a high performance engine that specificly is made for higher
octane.
putting gas boosters in your tank is like burning dollar bills
if your car is pinging with regular you have a mechanical or electrical problem and should fix it.

New vehicles with computers will retard the spark automatically so they will run on less octane without pinging. It may effect gas milage and
performance but won't damage the engine. I've never experienced any problems running Magna in my V-8 Dakota other than there have been times when I
wasn't able to buy it or I got cheated on the price (Santa Rosalia).

Why is it then---------
-----that both my 1994 Ford w/ a 460 V8, and my 1989 Isuzu Trooper with a 2.6 -4 cyl., both run fine on 87 oct. in the states, but ping horribly on
Mexican Magna??? and when I switch to Mex. premium, they both run just fine? Both vehicles are kept fine-tuned------- and folks, the Octane booster
works just like advertised, with Magna----i.e. the "ping" disappears.
David K.------you are very right about my truck self-destructing on NOVA, 25 years ago------NOVA left something to be desired. But that experience did
leave me very sensitive to "gas pinging" problems, and I do not want that to ever happen again. My old truck was in the Ford Garage in Ensenada for 7
weeks getting repaired (by the way, that Mexican-repaired engine is still running with no problems, in the same truck, today-----a 1969 Ford)

Years ago in the old country, I ran several test of mileage between the the "Regular" and "Premium" fuels available. While the Premium sometimes
gave a slight increase in miles to the gallon, it NEVER got as many miles to the dollar as the Regular.
I now use mostly diesel and prefer the Mexican diesel even though it's about $.90 a gallon less than in the US.

Your right, Lue--------
-------my response to Judy is a little misleading, and was intended only as a rebuttal to her limited comment.
I would NEVER burn premium if I thought that my engines would run safely on regular, and I NEVER burn premium in the USA.
My only point, and maybe my engines have some problem, is that "pinging" will eventually destroy an engine, and should be avoided.
I have run diesels, also, and I love them, even tho presently I do not have one.

Since most Pemex stations cannot even be trusted to give you the liters that the pump reads, all I was saying was, what makes you think that there is
any difference in the octane. IMHO

Wow, Judy------I see your point-------
-------I had not thought of it that way---and that brings in a whole different aspect.
Baja Cactus may have some comments about that------?
