gasoline

If I'm not mistaken, isn't the corvette (C6) supposed to take premium
gasoline? Anyone ever run it on regular gas? Will that harm the
engine in the LONG run? Please no flames on this, just asking for the
health of my future C6 and thanks.

REPLY: When on a trip, sometimes ive only been able to find 91 octane
instead of the 93 i can get around home. On 91 it runs fine for non
aggresive driving . Since a corvette is a non-average/ desirable car,
I wouldnt routinely run anything less than 91.

The above reply is incorrect and the engine command module is the same
as average automobiles that say they require premium fuel. The ECM
will adjust to run regular fuel unnoticed by the driver. I have run 3
consecutive tanks of regular fuel, 87 octane, through my C6 with no
detectable difference in performance and about 1 mile per gallon
difference in usage. That fuel was used in a very fast run through the
Smoky Mountains in 70° rain and the sun for a mixed weather run.

Actually ran a tank of regular through my '64 this summer in the heat
to see what it did and I could detect no pre-ignition on the engine.
Not sure why but wanted to know what would happen on a trip to be
ready in case today's fuel in premium was unavailable.

Earlier this year, we lost two west-coast
refineries and had spotty supply of 91 and 89.

My L98's electronics are slow and the difference
between 91 and 87 is obvious. I've heard that
first ping or two before the spark control
module responds. 87 is a 1/2 throttle operation
-- particularly on a hot day.

The C5 doesn't measure up to what the C6 can do
on regular. I've never heard anything on either
87 or 89 but high-altitude hill climbing is
definitely sick on 87.

REPLY: The above reply is incorrect ; he wouldnt be able to detect
pre-ignition using 87 octane because the knock sensor would pull back
ignition timing as an engine safety concern . Further, not all pre-
ignition can be heard in an automobile. Lastly, the owners manual for
a 2006 C6 says PREMIUM fuel only because the Designer of the LS2
engine demanded it for the various engine parameters including a
10.9-1 compression ratio. I would trust the Engines Designer before
the whimsical answer of this NG regular.

Wrong again, but that's to be expected. Spark knock and or
pre-ignition is seldom heard in an LSX engine and then the adjustment
it is so minor for 4 to 6 points in octane rating that it is about the
same as was used on the vacuum advance on the old mechanically
activated engines ignition. GMs designers put the air dam on them for
a reason also, but you said "REPLY: I took the air dam off of my 2006
C6 and it made no difference in engine temp at any speed . In fact,
the underside of the engine and exhaust gets cooled better now." Now
how does it, make no difference in engine temperature but runs cooler,
with no readings to prove your double speak? You use them as a crutch
on the fuel used but discard them on the air dam, make up your mind.

Actually the manual recommends 91 octane or higher for "best
performance", they did not demand it. You may also use middle grade or
regular unleaded gasoline rated at 87 octane or higher, but your
vehicles acceleration may be slightly reduced. If the octane is less
than 87, you may get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher as soon as
possible. Otherwise you might damage your engine. Page 5-5 in your
owners manual.

By the way dave, if you make another statement about me as you did in
another group on April 15th you will get a chance to meet me and my
lawyer in person. Want me to post it so everyone can see what type of
person you are?

As long as we don't need to pray to get you to do it.

(most already know what type of person dave is)
