An oil purifier designed for lubricating or turbine oil can often be adapted for engine oil filtration if it meets these conditions:
Engine oil has higher viscosity than insulating oil, so the purifier must heat it to 70–100°C for effective dehydration and filtration.
It should have multi-stage fine filters (1–5 microns) to remove carbon particles, soot, and metallic debris.
Vacuum or Centrifugal Separation:
A vacuum dehydration or centrifugal system can effectively remove water, fuel dilution, and gas contamination common in used engine oils.
The purifier’s seals, pumps, and filter media must resist the additives, detergents, and oxidation products found in engine oil.
Transformer oil purifiers are optimized for low-viscosity insulating oils and cannot handle thick, additive-rich engine oils efficiently.
Using a vacuum transformer oil purifier on engine oil may lead to filter clogging, slow flow, and incomplete dehydration.
If your goal is to clean, recycle, or reuse engine oil, you should use a:
Vacuum Lubricating Oil Purifier, or
Centrifugal Oil Cleaning Machine, or
Used Engine Oil Regeneration System (for large-scale recovery).
These are purpose-built for engine and lubricating oils, handling the high viscosity, oxidation, and sludge that transformer oil systems cannot.
? Summary
-- Oil Type ------ --------- Suitable Purifier ------------ ---------- Notes --------------------------------
Transformer oil Vacuum transformer oil purifier Low-viscosity, dielectric oil
Turbine/lube oil Vacuum lubricating oil purifier Medium viscosity
Engine oil Centrifugal or regeneration purifier Requires high-temp & strong filtration
Tip: If you want to extend your oil life, use a certified oil analysis service to determine the oil condition by testing oil samples rather than blindly using inappropriate filtration equipment.
