What an Oil Management Programme Is

Filtering one machine’s oil helps for a while. Where a plant runs dozens or hundreds of hydraulic power packs, gearboxes, compressors and turbines, the trouble comes back unless somebody keeps looking after the oil. An oil management programme does that: it lists the oil systems, tests each, sets a target, treats what fails the target and samples again on a schedule.

We treat the oil with our own machines at your site, and where the plant wants regular oil care, with our own team working there. Our centrifuge units heat the oil as they filter it and take out water, sediment and carbon particles. The method for each oil comes from its test, not from a fixed routine.

We have completed jobs at plants in Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, Maharashtra, Odisha, West Bengal and Uttarakhand.

What a Programme Covers

Each part is in the quotation only where your plant needs it; the quotation lists what is included.

What a programme covers
Part	What it means	What you get
Survey	The oil systems listed: machine, oil, volume and where each is sampled	One list of your plant’s oil
Targets	A cleanliness target for each system, from the machine maker’s figure where there is one	Something to measure against
Testing	A sample tested before the work at our NABL-accredited partner laboratory, and the particle count checked at your site	The state of each oil
Treatment	Centrifuge, vacuum dehydration, electrostatic cleaning or fine filtration, as the test shows	Oil back inside its target
Monitoring	Samples at regular intervals, so that a change shows before it causes a breakdown	An early warning
Care of the oil	Leaks found early, accurate top-up and tracking of oil use, where our team works at your site	Less oil used
Reports	Results before and after in ISO 4406 or NAS 1638 terms	Records to compare with your target

We can also supply filter paper for electrostatic oil cleaning machines.

How a Programme Is Set Up and Run

Walk the Plant
With your maintenance team we see the machines and their oils, list the systems and note the volumes, the sampling points and what already goes wrong.
Test Every Oil
A sample from each system is tested, and the particle count is checked at your site. The results show which oils are fine, which carry particles, water or varnish, and which look worn out and need checking against the supplier’s limits.
Set the Targets
With your engineers we agree a target for each system, the machine maker’s figure first, as an ISO 4406 code, and a water limit where it matters.
Treat by the Test
Each oil gets the machine its test calls for (table below). Oil that is still sound is cleaned and returned to service; oil that tests beyond the supplier’s limits is flagged for changing.
Sample Again, on a Schedule
Regular samples show whether each oil stays inside its target. A trend towards the limit calls for a visit before a breakdown does.
Report and Review
You get the before and after results for every treatment. We also look at the system the oil runs in, and say what should change there.

Which Treatment for Which Finding

The test decides. These are the usual pairings; several findings can apply to one oil. Acid number is one input, never a verdict: it counts acidic constituents, which additives and contamination also feed, and it does not show the additive life left. Its trend from the new-oil value, by one method, is weighed with the supplier’s limits and the other condition results.

Which treatment for which finding
What the test shows	Treatment	What it cannot do
Particles above the target	Fine filter elements, with a centrifuge first where the load is heavy	A centrifuge is usually less effective on the finest particles, so elements finish the job
Water above the limit	Our unit warms the oil so the centrifuge separates free water and droplets more easily; vacuum dehydration (LVDH) takes out the dissolved water and any emulsion that remains	No treatment is promised to clear every trace of dissolved water; the test after treatment shows what is left
Varnish or sticky deposits	An electrostatic cleaner, usually with a centrifuge	Oxidation products still dissolved in the oil are not necessarily removed
Sludge	A centrifuge; where it has settled in a tank, tank cleaning	No machine lifts sludge fixed to a tank floor or wall
Viscosity outside the supplier’s in-service limits, additives gone, or a climbing acid number that the other results support	Change the oil, once the results are judged against the oil supplier’s limits	Purification does not put back additives or reverse oxidation

Varnish: Why a Particle Count Can Miss It

Varnish is a thin, sticky film that forms when oil oxidises under heat. It coats valve spools, bearings and filter surfaces, and makes control valves stick. It is mostly dissolved in the oil or carried as particles too small for a standard particle count, so oil can count clean and still cause trouble.

An electrostatic cleaner holds the suspended part of it, with the fine particles, on filter paper between charged plates. Oxidation products still dissolved in the oil are not necessarily removed, so the oil is tested again and, where it is worn, changed.

A varnish test is a laboratory test. Tell us what your laboratory has reported; our NABL-accredited partner laboratory tests the oil when the quotation includes it.

Case study

On-Site Oil Management for Three Divisions of an Automobile Plant

The situation. An automobile plant ran three divisions, each with about 100 hydraulic power packs and many lubricated systems. Even with its own maintenance team it had frequent unplanned shutdowns and costly repairs. The oil was contaminated, leaks were common and oil consumption kept rising.

What we did. We put a team in each division: one machine operator who ran our mobile filtration units, and one fluid monitor who watched the power packs, spotting leaks early, topping up exactly and tracking oil use. One Ram Engineering supervisor led all three teams and was the plant’s single point of contact.

The result. As the plant measured, oil-related shutdowns fell by 95% and oil consumption by 20%. Our teams were on site every day and filtered the oil regularly, so the routine oil work left the plant’s own maintenance team, who could give their time to other jobs.

Where: Sriperumbudur, Kanchipuram district, Tamil Nadu, 2016.

A Programme, or One Treatment?

The programme is the main offer: it suits a plant that wants its oil looked after all year. It can run with our own operators and a fluid monitor at your site, as in the example above, or as regular sampling and treatment by what each test shows.

One treatment is quoted on its own for a single problem: a contaminated system, a tank of oil to recover, a machine before a major run. It covers one system, without the survey, targets and schedule that make a programme. Oil contaminated with about 50 per cent water, which often follows a heat exchanger failure, is such a case: we have recovered oil in that state, from experience rather than from the counted invoices below. Regular sampling can show a rise in water at the next sample, sooner than a breakdown would.

The quotation says which it is, what each side provides and how often we sample. For a larger job, an SOP we write sets out who does what.

How to extend industrial oil life

Records and Handover

Before work starts: the quotation lists the systems, the oils, the tests and the targets.
After each treatment: results taken at the same sampling point before and after, in ISO 4406 or NAS 1638 terms, to compare with your target.
In a programme: results kept for each machine, so that the trend shows; the quotation states how often we sample and report.
On request: a completed-work method statement, like the one issued for a centrifuge job in 2026.

Oil Management on Our Records

Our invoices name each oil, not this service, so oil management work is counted under the oil treated. Counting only the Chennai area, our job records hold 523 quenching oil, 318 hydraulic oil and 121 lube oil filtration jobs between 2000 and 2026. A job here means one plant in one month with an invoice or a completion record.

Safety on an Oil Management Job

Your permit-to-work governs the job; these are our own rules on top of it.

Connecting to a running machine: under your permit; we hook up at the reservoir and leave the pressurised circuit closed.
Opening a line: Before you open a joint or measure pipework in place, isolate the line, release the pressure, drain it and let it cool, and follow your plant’s safety procedure.
Hot and flammable oil: gloves and eye protection at each connection, drip trays and a spill kit, and no flame or hot work near our units.
Moving and high-voltage parts: the centrifuge is guarded and its bowl is not opened while it spins; the high-voltage part of an electrostatic cleaner is not opened while it is energised.
Waste: spent elements, filter paper, sludge and drained oil are kept in closed containers for your site’s authorised recycler.

Where It Is Used

Steel and metal manufacturing, cement plants and paper mills, where large hydraulic and lube systems run hot.
Power generation, where turbine and lube oil systems must stay clean.
Automotive plants, with many hydraulic power packs and lubricated systems.
Chemical and food processing plants, with compressors, gearboxes and hydraulics.
Turbine, hydraulic, quenching and compressor oils are the oils this service treats.

What Your Site Provides

Our past offers put these in the customer’s scope; your offer confirms them.

Permits and gate passes, and access to every plant area where we work.
Isolation with lock-out at every point where a line or housing is opened.

Questions Buyers Ask

What is the difference between filtering oil and oil management?

Filtering is one job on one system. Oil management is a continuing programme for the oils of the whole plant: test, target, treatment, and regular sampling afterwards. A single treatment can be quoted as well, and the quotation says which you are getting.

How often should oil be sampled?

No one interval fits every machine. Critical or hard-working machines are sampled more often than lightly loaded ones, and the machine maker’s guidance comes first. Sample sooner after a repair, a leak or a top-up with another oil. The quotation states the schedule for your plant.

Can you remove varnish from oil?

We can take out the suspended part with an electrostatic cleaner, usually with a centrifuge. Oil with dissolved oxidation products or spent additives may need changing, and a laboratory test tells which.

When do you advise changing the oil?

When the laboratory results, set against the supplier’s limits, show that the oil cannot be recovered: viscosity out of grade, additives gone, acid number and other condition results that all say the oil has aged badly, or another oil mixed in. Purification does not put back what the oil has used up.

What results can we expect?

At the automobile manufacturer in our example, oil-related shutdowns fell by 95% and oil consumption by 20%, as that customer measured them. Results depend on the plant, and we promise no figure for yours.

How is it priced?

A single treatment is priced per litre treated, or per job, and the transport of our units is its own line. A programme with a team at your site is quoted for the plant. For jobs outside Chennai, travel and stay for our team are included in the quote.
