NOTICE:
use only unleaded gasoline. The use of leaded gasoline will cause severe damage

Recommended:
REGULAR UNLEADED GASOLINE ONLY
CAUTION:
use only unleaded gasoline. The use of leaded gasoline will cause severe damage
to internal engine parts, such as the valves and piston rings, as well as to
the exhaust systems.
Note:
Your Yamaha engine has been designed to use REGULAR UNLEADED gasoline with a
Research octane number of 91 or Higher. (If knocking or pinging occurs, use a
gasoline of a different brand or PREMIUM UNLEADED fuel. Use of UNLEADED fuel
will extend spark plug life and reduce maintenance costs.
– YBR125ED and YBR125G, both motorcycle models have the same YBR engine.
Yamaha YBR125G RESEARCH OCTANE NUMBER of 91 or Higher
Petron-Regular Unleaded Gasoline Research Octane Number of 81 only
The Yamaha YBR’s Engine will run smoothly on its recommended RON 91 or
Higher
Yamaha Recommends REGULAR unleaded gasoline. But their recommended
gasoline does not have the required RON for a Yamaha Engine (does Yamaha know
about this?)
Only Premium gasolines offer the recommended RON. L
Gasoline RON Rating (Based on PETRON)
-Petron BLAZE 100- RON 100 (Premium Plus Gasoline) - Unleaded
-Petron XCS – RON 95+ (Premium Plus Grade Ethanol-blended Gasoline -
Unleaded
-Petron Xtra Unleaded – RON 93+ (Premium Grade Ethanol-blended Gasoline)
– Unleaded
-Petron Regular Unleaded – RON 81 (Regular Grade Gasoline) – Unleaded
(Gasoline engines with compression
ratio below 7.0 such as those found in motorcycles,
pumpboats and lawnmowers.
Yamaha YBR Engine Compression Ratio:
10.0:1
Yamaha FZ16 Engine Compression Ratio: 9.5:1
Yamaha Mio Soul Engine Compression Ratio: 8.8:1
Higher Engine compression ratios will however make gasoline engines
subject to engine knocking if lower
octane-rated fuel is used, also known as detonation.

Protect
Your Engines From Alcohol Fuel Damage!
Ethanol is an Alcohol Fuel.
Ethanol is an alcohol renewable fuel, made from corn or grains, which is
used to oxygenate gasoline fuel at the pumps.
Ethanol is hygroscopic (will absorb water), and is an excellent solvent
(dissolves materials).
Due to ethanol's affinity for water, phase separation and water
contamination occurs very quickly.
Ethanol Fuel - What's the danger?
Simply put, ethanol is an excellent SOLVENT (dissolves plastic, rubber,
fiberglass and more), and unlike MTBE ethanol will ABSORB WATER, which can
cause serious problems to some engines.
The presence of ethanol in fuel is rapidly rising.
At this time, most gasoline stations have already switched over to E10
ethanol-blended fuels, replacing MTBE, for oxygenating fuel.
Based on the laws passed in 2006 (Clean Air Act) and other EPA and U.S.
government laws, ethanol blend fuels now are present in our fuel supply.
You may not realize, that you are already buying fuel that contains
ethanol...
The gas pumps in several states still are not required to disclose that
the gasoline contains ethanol alcohol.
Non-Ethanol Fuel:
Petron Blaze 100
PETRON BLAZE 100 is the first and only pure 100 octane premium
gasoline in the Philippines. It is formulated and developed to unleash the full
potential of modern and high performance vehicles. Its high octane combined
with high performance fully synthetic detergent additive and organic combustion
enhancer provides optimum engine performance for smooth and exhilarating
driving experience. Petron Blaze 100 is the advanced unleaded
gasoline that provides the following performance benefits:
Enhanced
power and acceleration
Excellent engine cleaning
action
Better fuel economy and
reduced emissions
Application:
All gasoline cars
Luxury cars, sports cars, big
bike
Cars fitted with catalytic
converters
Cars not compatible with ethanol-blended
gasoline J

PETRON REGULAR UNLEADED is a motor fuel with controlled volatility for maximum economy, easy
starting and good acceleration. It is suitable for low compression gasoline
engines.

Gasoline engines with compression
ratio below 7.0 such as those found in motorcycles, pumpboats and lawnmowers.

Gabby’s Thoughts: after a detailed 3 day-mind hammering research
on different version of Owner’s Manuals (YBR125) and well-known petroleum
products effects on motorcycle engines.
-Motorcycle Owner’s Manual
for YBR125 had been revised in 3 different versions.
Printed in China 2006 and Printed
in China 2008 are found to be more detailed and complete.
Than the later Printed in
the Philippines 2009 version which lacks the following info:
-Engine Octane Requirement,
-Approving the use of
PREMIUM Unleaded gasoline, if engine knock is experienced.
-Servicing Manual (Yamaha’s
Mechanical Secrets).
-and other useful
information.
(Yamaha YBR Custom
(Europe), YBR125ED, YBR125S, YBR125G2009 and YBR125G 2011 had the same engine type.

Petron launches Blaze 100
Petron Corp. breaks another boundary in fuel technology with the recent
introduction of the new Petron Blaze 100, the only premium gasoline in the
Philippine market with a Research Octane Number (RON) of 100. The new fuel
product was formulated to ensure engine power and to unleash the full potential
of high-performance vehicles.
The first-of-its kind premium gasoline guarantees the following
performances benefits: Excellent engine responsiveness and optimum power and
acceleration; high quality engine cleaning action with the use of fully
synthetic detergent additives; and better fuel economy and reduced emissions
with its unique organic combustion enhancer.
With a 100 RON, Petron Blaze 100 has exceptional resistance to “engine
knocking” which results in uneven fuel burn and greater fuel consumption. And
since it does not contain ethanol, it can be safely loaded in older vehicles that are
not equipped to take in ethanol-blended gasoline.
The new Petron product also exceeds stringent European emission
standards (Euro 2) making it environment-friendly.
“As the market leader in the Philippine oil sector, we introduce
products that are relevant to Filipino motorists,” Petron Chairman and CEO
Ramon S. Ang said.
