New member here. I have a '99 Red. What octane gas do you people use? Owner's manual says "not to exceed 91 octane", but dealer says to use 93 octane.

What is your preference and why? Thanks fo ryour help.

I use hi-test always.

I have gotten bad gas and heard a little pinging.

Welcome to POA, glad you made it.

Okay let's clear up some of the myths about
gasoline. The octane rating in gasoline is
defined as the fuel's ability to suppress
knock(also known as pinging). Higher octane
gasoline does have better cleaning or more
powerful properties than the lower octane
gasoline. The air & fuel charge in the
combustion chamber must be in a controlled
burn,when too low an octane fuel is used, the
air fuel mixture explodes which cause the
knocking noise especially during acceleration
This can lead to engine damage if prolonged.

There are no substanial differences with
Unbranded gasoline versus the majors, such
as Exxon,Amoco,Shell,etc., because they all
come from the same PIPELINE. The Unbranded
companies usually purchase the excess fuels
from the major companies if they over produce. So any given day an Unbranded station may have Exxon, Amoco or Shell mixed
together in the same tank, but the octane is
still retained. As far as watered down gas,
a station owner will have to be insane to
contaminate over $50,000 dollars worth of
inventory. However sometimes rain water do
get into the fuel, but there are many safeguards to prevent and warn if this occurs. The only suggestion I will make is
not to fill your Kat up at the same time when
there is a tanker delivering gas at the station, because that can stir up sediments
in the fuel that ultimately can end up in your gas tank, even though the fuel is filtered thru the dispenser.

One last thing, using a higher octane fuel
certainly will not hurt the engine, but its
a waste of money. Use the lowest octane fuel
possible as long as the engine DOES NOT PING.

Midlife, thanks for the explaination. I agree with what you have said

BUT

I still like to use AMOCO ULTIMATE or SHELL premium if ay all possible

I guess it is peace of mind that the gas brand is ONLY what the dealer sells not a blend of many.

too many commercials to brain wash us

Owners manual for 2000 recommends minimum 91 octane and purchase of fuels with higher octane is not recommended.

The 2000 Prowler Service Manual, page 0-2
states: Prowler engines require the use of unleaded fuel to reduce exhaust emissions.
Use premium unleaded gasoline having a minimum of 91 octane rating of 91(R+M)/2.
Higher octane premium unleaded gasoline CAN
BE USED IF DESIRED. The service manual
supercedes the owner's manual.
