Motorcycle Engine Oils — Industrial Formulation Handbook (Volume 1)
About this book
Motorcycle Engine Oils — Industrial Formulation Handbook (Volume 1) is a print-grade technical formulations guide covering 4-stroke and 2-stroke powersports lubricants. It details 48 starting-point formulations across 10 sub-categories, providing lubricant blenders, chemists, and entrepreneurs with the chemical foundation to manufacture wet-clutch compatible (JASO MA2/MB) and high-shear stable engine lubricants.
The technology
The handbook covers powersports tribology: integrated sump mechanics, JASO T 903 wet-clutch friction indexing, stay-in-grade viscosity index improver selection, antiwear ZDDP synergies, and two-stroke smokeless ester chemistry (JASO FD / ISO-L-EGD).
Inside the formulations
All 48 formulations contain 200 kg pilot batch component tables (% w/w and sourcing tier), viscosity grade, physical/chemical target values, blending sequences, QC targets with cited ASTM test methods, and chemical formulation basis.
What you get

Who is this book for?
Motorcycle Lube Blender
You blend or manufacture powersports lubricants and need starting formulations across 4-stroke (JASO MA2) and 2-stroke (JASO FD) categories that meet mechanical shear stability requirements.
Product Manager
You want to launch a specialized motorcycle lubricant brand with clear tiering from economy mineral grades to synthetic racing-tier ester lubricants.
Research Chemist
You develop engine lubricants and need high-rpm reference formulations to balance clutch friction coefficients against gear wear and cylinder protection.

Frequently asked questions
They are validated starting points. You will need to bench-test and adapt treat rates to your specific raw material lots, but you start from a working formulation — not a blank sheet.

Yes. The handbook opens with a fundamentals section that explains the underlying chemistry and ingredient functions before presenting formulations — so beginners can follow the rationale, not just the recipe.
PCMOs are loaded with friction modifiers (like organo-molybdenum) to improve fuel economy. In motorcycles with integrated sumps, these modifiers deposit on the wet multi-plate clutch, causing plates to slip under torque, resulting in glaze and transmission failure.
JASO MA2 defines the highest friction performance limits in the JASO T 903 clutch test, indicating the lubricant is suitable for high-torque powersports engines where wet clutch slippage must be prevented.
Motorcycle sumps lubricate transmission gears that grind polymer viscosity index improvers. The book specifies high shear-stability index (SSI) polymers (like star-structure polymethacrylates) that maintain viscosity.
