ISO VG 46 HM hydraulic oil (DIN 51524-2 HLP) in Australia
For an ISO VG 46 anti-wear hydraulic oil (category HM, or HLP in the German standard), Bulk Lubricants Australia supplies two TotalEnergies grades: Azolla ZS 46 and the zinc-free Azolla AF 46. Both are classified DIN 51524-2 HLP, ISO 11158 HM and ISO 6743-4 HM, both appear on Bosch Rexroth's RDE 90245 fluid list, and both carry Parker Denison HF0, HF1 and HF2 approval. We supply them from Perth, with freight Australia-wide.
Compare the two ISO VG 46 HM grades
From TotalEnergies product information and Bosch Rexroth’s fluid list (see sources below). Always check the category and approval your equipment maker specifies.
| Product | Classifications | Bosch Rexroth | Parker Denison | Zinc-free | TotalEnergies market segments |
|---|---|---|---|---|---|
| Azolla ZS 46 | DIN 51524-2 HLP, ISO 11158 HM, ISO 6743-4 HM | Listed (RDE 90245) | Approved HF0, HF1, HF2 | Not described as zinc-free | Automotive manufacturing, mining |
| Azolla AF 46 | DIN 51524-2 HLP, ISO 11158 HM, ISO 6743-4 HM | Listed (RDE 90245) | Approved HF0, HF1, HF2 | Yes: no zinc or heavy metals | Steel, cement and materials |
Choosing a grade
- Start with the manual. It names the viscosity grade (here ISO VG 46), the fluid category (HM / HLP or HV / HVLP) and any pump approval, such as Bosch Rexroth RDE 90245 or Parker Denison HF0, HF1, HF2.
- Mining and mobile plant. TotalEnergies lists Azolla ZS 46 for mining and as suitable for Komatsu.
- Zinc-free requirement. Azolla AF 46 does not contain zinc or heavy metals, according to TotalEnergies.
- Wide temperature range or outdoor plant. If the maker calls for HV / HVLP, look at Equivis ZS 46 (DIN 51524-3 HVLP, ISO 11158 HV, viscosity index 155 on its data sheet) rather than an HM oil.
Common questions
- What does ISO VG 46 HM mean?
- ISO VG 46 is the viscosity grade: 46 mm²/s at 40 °C. HM is the ISO 6743-4 category for anti-wear mineral hydraulic oils; the German standard DIN 51524-2 calls the same type HLP. Your equipment manual or pump maker names the grade and category it needs.
- Which TotalEnergies hydraulic oils are ISO VG 46 and DIN 51524-2 HLP?
- Azolla ZS 46 and Azolla AF 46. TotalEnergies classifies both as DIN 51524-2 HLP, ISO 11158 HM and ISO 6743-4 HM.
- What is the difference between Azolla ZS 46 and Azolla AF 46?
- Both are ISO VG 46 anti-wear hydraulic oils with the same DIN and ISO classifications. TotalEnergies says Azolla AF does not contain heavy metals or zinc. Azolla AF 46 also lists AIST 127 and SAE MS1004. TotalEnergies' Australian catalogue lists Azolla ZS 46 for automotive manufacturing and mining, and as suitable for Komatsu, and Azolla AF 46 for steel, cement and materials.
- I need an Azolla ZS 46 equivalent. What should I match?
- Match the specification rather than a brand name: ISO VG 46, DIN 51524-2 HLP or ISO 11158 HM, and any approval your pump maker asks for, such as Bosch Rexroth RDE 90245 or Parker Denison HF0, HF1 and HF2. Within the TotalEnergies range, Azolla AF 46 carries the same viscosity grade and classifications and is zinc-free. Check with your equipment maker before changing the fluid in a system.
- Are these on the Bosch Rexroth fluid list?
- Yes. Bosch Rexroth's RDE 90245 list (edition 2026-10-15) includes TotalEnergies Azolla AF and Azolla ZS as HLP (HM) fluids in ISO VG 32, 46 and 68. Each entry has a validity date, so check the current edition for your pump.
- When would I use an HV oil such as Equivis ZS 46 instead?
- When the equipment maker calls for a high viscosity index HV or HVLP fluid. TotalEnergies classifies Equivis ZS 46 as DIN 51524-3 HVLP and ISO 11158 HV, and describes the range as especially suitable for hydraulic systems working under extreme temperature variations and equipment operating outside. Its data sheet gives a viscosity index of 155, against 113 for Azolla ZS 46.
- Can I buy these in Perth or get them freighted to site?
- Yes. Collect from the TotalEnergies Perth warehouse at 22 Wildfire Road, Maddington WA 6109, or Bulk Lubricants Australia freights Australia-wide. Price, pack and freight are confirmed on the quote, and the TotalEnergies technical and safety data sheets are available on request.
