OCP Lubricants
Compressor oil stopped evolving.
So we started over.
Most compressor lubricants on the market today are refinements of formulations that are decades old. We bought a lubricant plant in Austria and formulated ours from an empty sheet of paper.
Why nothing changed for so long
A compressor lubricant that works is a comfortable business. It sells year after year, it is specified in manuals, and it carries no pressure to change. When a formulation is already accepted by the market, there is very little commercial reason to spend years and a great deal of money rebuilding it from the ground up.
So the category settled. Base oils improved slowly, additive packages were adjusted at the margins, and the fundamental recipes stayed close to where they were decades ago.
We came into Europe as the newcomer with nothing to protect. That turned out to be the advantage.
We bought the factory
Instead of buying finished oil and putting our label on it, OCP acquired a lubricant manufacturing plant in Austria. That decision changed what was possible: we control the formulation, the additive chemistry and the quality control, rather than choosing from someone else's catalogue.
Formulating from zero is slow and expensive. It also means that when a compressor needs something the market does not offer, we can build it.

The formulation, in numbers
Every figure below is from our published product data sheets, measured to ASTM standards.
A perfect foam score, three times over
Measured to ASTM D892 across all three sequences. Foam is not cosmetic: air bubbles carried into the oil circuit reduce lubrication at the bearings, disturb the separator and accelerate oxidation. A zero in all three sequences is the best result the test can give — and every oil in our range returns it.
The best possible copper rating
ASTM D130, three hours at 100 °C. Compressor coolers and lines are full of copper and copper alloys. 1a is the top of the scale: effectively no attack on the metal.
Corrosion protection tested in sea water
ASTM D665 method B uses synthetic sea water, the harsher variant of the test. It matters for compressor rooms in humid plants, coastal sites and anywhere condensate is a fact of life.
Viscosity index, OCP Oil Prime 12000-46
A typical mineral compressor oil sits near 100. A higher viscosity index means the oil changes its thickness less as the machine heats up: easier starts when cold, a stronger film when hot. Across our own range the index climbs from 105 in the entry product to 166 in Prime.
Flash point, OCP Oil Prime 12000-46
Higher thermal headroom than the >200 °C typical of the category. Combined with high thermal conductivity, the fluid carries heat away from the screws instead of holding it.
Readily biodegradable base stocks
Prime 12000-46 is blended on readily biodegradable base stocks, measured to OECD 301B — unusual for a long-drain compressor lubricant.
Varnish is what actually kills long drain intervals
Under heat and oxidation, ordinary lubricants leave a hard lacquer on coolers, screws and valves. It insulates surfaces, raises running temperature, and quietly steals efficiency long before anyone notices a problem. It is the reason many compressors never reach the service interval printed on the drum.
OCP Oil Ultra 8000-46 was designed specifically for long service intervals where varnish deposits in coolers and screws are critical — varnish-free operation is the design target, not a side effect.
OCP Oil Prime 12000-46 goes further: it does not only avoid forming varnish, it dissolves varnish left behind by previous lubricants.
A PAG you can actually switch to
PAG-based coolants have always offered the strongest performance and the worst changeover: they are typically not miscible with mineral or PAO oils, so switching means flushing, cleaning fluid and downtime.
OCP Oil Prime 12000-46 is built on an oil-soluble PAG. It is fully miscible with mineral, PAO and ester-based products — and forgiving even if the changeover is not done perfectly. You get PAG performance without the PAG changeover.
