HYDRATEC HVI 46 Technical Data SheetHYDRATEC HVI 46 - Hydraulic Oil
Aztec oils Hydratec HVI 46 is a high-viscosity-index, mineral-based hydraulic fluid designed for demanding hydraulic systems that operate across wide temperature ranges and high pressures.
Engineered with a blend of solvent-refined base oils and viscosity-index improvers, it delivers stable performance, superior protection and efficient, reliable operation for machinery exposed to variable conditions.
Recommended Applications
- Hydraulic systems with vane, piston, or gear pumps operating under high pressure
- Industrial machinery requiring consistent oil viscosity in both warm and cold environments
- Mobile equipment (e.g. construction, lifting) with variable temperature exposure
- Systems demanding wear protection and long-term stability, such as power packs and hydraulic power units
- Application where fluid emulsification is a concern - ideal where good water-separation is required
- Suitable for: Denison HF-0, HF-1, HF-2 DIN 51524 Part III HVLP ISO 11158 Type HV ISO 6743-4 Type HV
Key Benefits
- Exceptional Temperature Stability - thanks to its high viscosity index, this oil maintains a more consistent viscosity in hot and cold conditions
- Outstanding anti-Wear Protection - robust additive system protects pumps, valves and motors under severe load
- Excellent Oxidation Resistance - helps prevent gum and lacquer formation, extending fluid life
- Good Demulsification and Water Separation - minimises emulsions, reducing risk of damage from water contamination
- Low Foam & Fast Air Release - ensures stable performance under dynamic hydraulic conditions
- Energy Efficiency - high VI and stable viscosity contribute to reduce drag losses and smoother system operation

HYDRATEC HVI 46 - Hydraulic Oil Frequently Asked Questions (FAQs)
What does 'HVI' mean in HYDRATEC HVI 46??
HVI stands for High Viscosity Index - meaning the oil is designed to maintain a more stable viscosiity across a wide temperature range, reducing viscosity losses when hot and maintaining fluidity when cold
Can I use HYDRATEC HVI 46 in any hydraulic system?
It's suitable for many systems, especially those with high pressure or wide temperature swings, but always check your OEM's recommended fluid specification and ISO type (e.g. ISO 11158 Type HV)
Does HVI 46 offer better protection than standard HM 46 hydraulic oil?
Yes - compared to standard anti-wear HM oils, HVI provided superior performance in terms of thermal stability, oxidation resistance and fluidity over a broader temperature range
Is HYDRATEC HVI 46 compatible with materials in my hydraulic system?
It has good compatibility with standard seals and components, but if your system uses unusual materials (e.g. very soft elastomers) always check the OEM recommendations
How ofter should i change this hydraulic oil?
Change intervals depend on your machine's duty cycle, operating temperature, contamination level and OEM advice. Because HVI fluids resist oxidation well, that are often good candidates fro longer drain intervals - provided proper system maintenance and oil sampling.
HYDRATEC HVI 46 - Hydraulic Oil Delivery Information
Tanks:
The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page. Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.
Tanks Over 2500L – Articulated Lorry – Customer Offload:
These tanks will be delivered on an articulated vehicle (approximately 16.5m long x 2.6m wide x 3m high) which has no offloading on board, it is the customer's responsibility to offload the tank, which may require a telehandler / forklift. Curtain sided vehicles are also used, so please note that if there are obstacles or hanging branches on the road to the delivery site etc, the driver may refuse to drive the vehicle to the customer's location due to the possibility of damaging the vehicle. Please let us know if there are any obstructions before delivery, so we can arrange alternative transport.
18 Tonne Tail Lift HGV
This vehicle is the size of the largest bin lorries (for comparison) and is approximately 8.2m long x 2.6m wide x 4m high, often curtain sided so please note that if there are hanging branches etc, these vehicles will not attempt to drive down due to the possibility of damaging the vehicle and so it is recommended that a smaller vehicle is requested. Tanks will be lowered to the ground but not positioned as this is a kerbside delivery. If a smaller vehicle is required, please email us at sales@fueltankshop.co.uk quoting your order number and name.
HIAB Delivery
HIAB delivery is available but must be requested and there will be an additional cost for this service. If a HIAB delivery is required, please email us at sales@fueltankshop.co.uk quoting your order number and name, and we will come back to you with a price for this service.
Accessories:
Most accessories will be delivered within 1-3 working days (certain products and postcodes may take longer, please check the product page for update to date information). If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock, we will advise you of the expected lead time, and you will of course have the opportunity to cancel with a full refund.
