Heavy-Duty Diesel Engine Oils (HDEO) — Formulation Handbook
About this book
Heavy-Duty Diesel Engine Oils (HDEO) — Formulation Handbook is a professional-grade technical reference covering 50 starting-point formulations across 10 sub-categories. Built for lubricant blenders, R&D chemists, and automotive entrepreneurs, it covers the complete commercial diesel range: from high-TBN mono-grades for developing markets to synthetic API CK-4 multigrades, fuel-economy FA-4 oils, heavy-duty off-highway blends, and ultra-premium low-SAPS long-drain formulations.
The technology
The handbook explores the physical chemistry of compression-ignition engine lubrication, including the tribochemistry of ZDDP film formation under extreme loading, organic molybdenum boundary lubrication, and soot-dispersancy mechanisms under high EGR rates. It breaks down the formulation rules for base oils (API Groups I to V), metallic detergents (sulphonates, salicylates, phenates), ashless dispersants (borated and bis-PIBSI), polymer viscosity index improvers (OCP/PMA), and pour point depressants.
Inside the formulations
Each of the 50 formulations is presented in a structured card containing a 100 kg reference batch table (% w/w, component function, and sourcing tier), calculated TBN and ash contributions, target specifications (API, ACEA, OEM), manufacturing SOP, QC limits (KV100, KV40, VI, CCS, HTHS, Flash Point, Pour Point, NOACK), stability notes, and variants.

Who is this book for?
Commercial Lube Blender
You blend or contract-manufacture lubricants for transport fleets, bus services, or construction fleets, and need validated starting-point formulations from SAE 40 mono-grades to synthetic 10W-30 CK-4.
R&D Chemist
You work in industrial formulation and need a solid reference for soot dispersancy, TBN management in high-sulphur markets, and shear-stability criteria to benchmark your products.
Automotive Fluid Entrepreneur
You want to launch an own-brand heavy-duty oil series for transport companies and need a clear formulations reference, sourcing tips, and scale-up guidance.

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.
Yes, it provides starting formulations designed to meet current performance standards, including API CK-4, FA-4, and European ACEA E6/E9 sequences, incorporating SAPS constraints (ash, phosphorus, sulphur) required for modern DPF/SCR aftertreatment.
CK-4 formulations maintain a high HTHS viscosity (≥ 3.5 mPa·s) for maximum hardware protection and backward compatibility, while FA-4 formulations are low-viscosity (HTHS 2.9–3.2 mPa·s) designed specifically for modern fuel-economy engines.
Yes, the handbook covers mono-grade and standard multigrade formulations with elevated TBN levels (up to 14–16 mg KOH/g) utilizing robust calcium sulphonate/phenate detergent packages to neutralise acids in markets where fuel sulphur exceeds 500 ppm.
Yes, Sub-category 9 covers premium long-drain formulations using Group IV PAO and Group V ester co-bases combined with low-SSI polymers (SSI ≤ 15) to achieve 100,000+ km drain capabilities.
