Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
Fuel with a lower rating could cause the emission control system to lose effectiveness. It
could also cause engine knocking and serious engine damage.
Your Mazda will perform best with fuel listed in the table.
Fuel
Octane Rating* (Anti-knock index)
Premium unleaded fuel
91 [ (R+M)/2 method] or above (96 RON or above)
*U.S. federal law requires that octane ratings be posted on gasoline station pumps.
You may use a regular unleaded fuel with Octane Rating from 87 to 90 (91 to 95 RON) but
this will slightly reduce performance.
CAUTION
•
•
•
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
Your vehicle can only use oxygenated fuels containing no more than 10% ethanol by
volume. Damage to your vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline contains any methanol. Stop using gasohol of any
kind if your vehicle engine is performing poorly.
Never add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10%. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".
Vehicle damage and drivability problems resulting from the use of the following may not
be covered by the Mazda warranty.

•
Gasohol containing more than 10% ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

Automotive readers have rated 2003 Mazda MX 5 Miata Owners Manual 1.0 out of 1.0 based on 1 product reviews. No matter what I do this will not download. I have followed all instructions and even the instructions for override because Windows states this software has undesirable problems ( but it makes the same claim for all Mazda Manuals I've found on the net) Now I am also unablre to review pages of the manual. I'm being stopped at the cover. I need access to this manual. Please help.
