Spend a day at the docks and the gas storage places. You'll see all sorts
of truck getting the same gas for different brand stations.
It may be possible that the truck responded to a different gas, but there
may be other reasons. Why was it sluggish? Is there some mechanical reason
that it was not running properly?
Unless something was different than normal (he may have changed computers
for all I know) there is no difference in 99% of the cars designed for 87
I drive about 30,000 miles a year, sometimes as much as 50,000. I've tried
different brands, different octanes, and if the car is running properly I've
not see any difference. This is in a half dozen cars I've driven over the
past 15 or 20 years.
I go for cheap and have no problems. My older car has 139,000 miles (the
plugs were changed at 75,000) and it starts, runs, and gets the same gas
mileage as the day it was new. My new car has 90,000 miles, original plugs,
Try the 76 and report back. Chances are thee will be no difference except a
few $ out of your wallet.

My 1983 Honda Civic manual says "use regular gas," but when I do, my
car runs rough, stalls, and gets low fuel-miles. Auto mechanics say
that if your car runs better with premium, use it. I've even heard
recommendations of occasionally using premium, perhaps every 4th fill
up, which helps clear out injectors, plugs, and exhaust.
Is your friend buying his gas accross the border in Nevada?
This is a common practice for some folks who live near the border and
live in Cali..................It's cheaper and it's better gas too,
with less additive crap in it. I read recently that California is
fairly PO'd about Truckers doing that before they drive into Theor
state to avoid the cost, so They are going to ( may have already done
so) make it where there is a cost per mile to operate vehicles in
California..........although I don't think they have yet.

one small step for man,.....
One giant leap for attorneys.
Don't know about CA or other western states, but here in the east, truckers
must have fuel use permits for each state. They report the miles driven and
pay the fuel tax accordingly. You get a credit for fuel purchased in that

the full price, like chevron, 76, etc.
the discounters, like costco, sams, vons
the unknown mom n pop places.
the discounters have a reputation to uphold, so their stations are
generally clean, and they still have a good price. i just dont trust the
unknowns. yes, they all get gas from the same sources. but who knows
when the mom n pop places replace their gas pump fuel filters, etc.
I found that premium BP, Amoco or Shell makes my car run smooth and
efficiently. If I buy Racetrack or Direct premium gas, my car tends
to run rough and stalls. My car is a 1983 model and it is very
sensitive. Some gas stations will have higher water content which
will cause rough idling, especially during the winter months. I've
heard truckers say that 76 gas is all they buy.

One of my cars is an '83, too. It doesn't run as smoothly as it used to.
Thing is, I rarely use that car. It's a Chrysler Town and Country
mini-wagon, and I only use it for Home Depot runs for big sheets of
plywood and stuff like that. Since I don't do that too frequently, most
of the time I use it is to give it a spin just to keep it running OK. My
mechanic said I should think about keeping the gas tank topped up to
minimize the effect of water condensing from the air in the tank, so I
try to keep it pretty near full. I guess I'll try the 76 in that car and
see if it runs better. My other car's running better. It's my "every
day" car, although I often go a couple of weeks or more without using
In Australia it seems we have different octane ratings to you. Ordinary unleaded gas
(we call it petrol) is 91
octane. Premium is 95 or 96. There are some super premiums at 98 octane.
I have an 89 Ford Telstar (which is a rebadged Mazda 626, made by Mazda in Japan).
It has about 100k miles on
My mechanic recommended Shell Premium (96 Octane) as he said while it costs more
(approx 10%), the
decreased fuel consumption will often make up the difference, plus the engine will
I thought it was hogwash until one day when we were on a long trip in summer (when it
was 95-100 degrees F air
temperature), the engine was getting very hot (almost at the top of the gauge) so the
next lot of fuel we put in was
preimum. The engine immediately went back to normal temperature. Plus we have found
the lower fuel
consumption more than makes up for the extra cost, so we have stuck with premium.
91 octane fuel is below the common octane levels in many other countries, but usually
high-selling imported cars
sold here are modified to run ok on 91. However some cars (sporty cars e.g. Mazda
RX8, or low selling models
like VW Polo) are not modified so they require 95 octane.
Here we also get coupons for Caltex and Shell from the two major supermarkets. Spend
$30 AUD or more and
gets 4c AUD / litre off the next petrol purchase - that's about 4% off.
Petrol here is about $1.00 AUD / litre - that's about $2.95 USD per US gallon.
Premium is about 10% dearer.
This is Turtle.
I have been down this road on gas for my company trucks for years and came up
with two things to do and you will do fine with fuel.
1) look in the book that come with the auto and get the Octane Rated gas your
suppose to be burning. Then when going to gas up Get that octane rated fuel only
for your auto is designed to burn that octane fuel. The ratings will be from 86
to 93 octane ratings. Us the one the auto maker say for your computor on the
auto is set to burn that octane fuel. I have my truck that are to be burninmg 87
octane fuel. I can put 93 octane fuel and it seems I get worst mileage than with
87 octane fuel. Now the newer model have a sencer to adjust the fuel flow rate
to the engine to take care of 93 in a 87 octane car but it will take a 1/2 tank
or so for your computor to get use to the higher octane fuel. Pick out the
octane rating your auto should be using from the book in the auto and use it.
2) Alway buy your gas at stations that move a lot of fuel to not get old gas
sitting in the tanks for too long and start to degrade. Gas will be very poor if
left in a tank for 18 months and need rerefining of it.
Tell your Mechanic to go read his book for his auto on what octane fuel he
should be burning and he will solve his problem with fuel.
Now 20+ years ago Amoco had White Gas and others has regular leaded gas. This
white gas was better but when regulation and unleaded gas come along. The white
gas was history. Your Mechanic has these left over thoughts of this era and I
still have them but they are just thoughts now a days.
When all else fails Read the instructions.
I see in another post that you're from CA. So am I. This makes a
The 76 station near my house has a HUGE sign that advertises "NO MTBE."
Don't know if all 76 stations are MTBE-free, but most of the others
haven't gotten rid of it yet. That probably accounts for the difference
in mileage. I don't know about the running smoother thing, though.
I heard that newer cars/trucks need the octane they're designed for even
though they run fine (no knocks) w/ lower octane gases. The computers
adjust to make them run ok, but the performance and efficiency go down.
So I think it just depends on the car.
