PowerŪ only uses Mobil One Fully Synthetic Oil Approved by Briggs & Stratton
All oils are not created equally. The following is an overview of synthetic oils and their application in air-cooled engines.
- Better Viscosity Temperature Response (Higher
Viscosity Index) – This means that a synthetic offers protection over a wider temperature range than conventional oil.
One can run multi viscosity synthetic oil year round without compromising oil consumption.
- Better Low Temperature Fluidity (Lower Pour
Point) – This means that a synthetic will flow at lower temperatures than similarly formulated conventional oil. This results in easier pull starting or cranking and better lubrication protection
at colder temperatures.
- Better Thermal Stability – This is the
oil’s resistance to breakdown at higher temperatures. Synthetics resist
high temperature breakdown much better than conventional oils which results in increased hydrodynamic bearing film thickness
(longer bearing life) and reduced oil consumption. Since a small air-cooled engine
runs extremely hot, compared to a liquid cooled engine, this is important.
- Better Oxidation Stability – At high
temperatures oils oxidize, synthetic inherently hinder this oxidation process much better than conventional oils allowing
better protection for longer periods.
- Lower Volatility – Volatility is the
oils tendency to “burn off” at higher temperatures. High volatility
means it burns off easily, low volatility means it doesn’t. Synthetics
have a much lower volatility than conventional oils meaning it will be around longer to protect your engine.
- Better Deposit Control – In conventional
oil, deposits readily develop and the additive chemistry has to deal with them. A
synthetic actually hinders the development of deposits.
- Better Wear Control – All of the things
mentioned above lend themselves to better protection and better wear control of you engine, even under severe operating conditions. Since synthetics have better “inherent strength” they have the ability
to keep functioning at the highest level for the longest possible time. Mobil One
is the same formula as Briggs & Stratton fully synthetic oil and has been tested and approved for use
in hotter running air cooled engines and therefore is “Warranty Certified”. All
the other synthetic oils are formulated for water-cooled engines only.
