Formulating on Group II in India When Group I Is No Longer the Default
Group II is cleaner and more stable than Group I, and a worse solvent for some additives and grease soaps. Copy-pasting a Group I treat rate onto Group II is how you get haze, additive dropout and a grease that will not cook. The formula has to move with the base oil.

- Group II is cleaner and more stable than Group I, and a worse solvent for some additives and grease soaps.
- Indian Group II availability changed what a blender can honestly call semi-synthetic. Saturates and sulfur shift additive response: some sulfonates and ZDDPs behave differently than on Group I. Formulate on the oil you can buy twice, not on
- Name the test method on any number that reaches a TDS.
- Patents and papers are prior art, not a product Lubechem sells.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.
What this page is for
Evergreen supply-chain topic. Existing base-oil guide is taxonomic; this is the ‘what do I do in the plant’ article. Images are labelled conceptual illustrations. Patents and papers are cited so you can go read them.
Bench screens before anyone argues about a brand name
| Question | Method | Decision |
|---|---|---|
| Is the grade even itself? | D445, CCS/MRV if engine, VI | Fix KV before additive heroics |
| Will it stay put? | Noack, flash, pour, foam | Volatility and air release kill more launches than TBN |
| Will it protect metal? | D4172, D2783, rust, copper strip | EP is not antiwear; do not confuse them |
| Will it live? | Oxidation, RPVOT, PDSC, field drain | A 4-ball pass is not a 500-hour drain |
People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.
Questions plants actually ask
Is Group II base oil formulation India a drop-in for whatever we run today?
Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.
Can we put Group II base oil formulation India on the TDS because a patent or paper mentioned it?
No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.
Who owns the formula if Lubechem develops it?
Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.
What should Blenders reformulating as Group I tightens send in the first brief?
Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
