How To Choose The Right Oil For Hydraulic Systems?

central-hydraulic-oil 21 Sep 2020

In a hydraulic system, the most crucial component happens to be the hydraulic fluid. If you have to guarantee the highest efficiency and optimum performance for your hydraulic system, it is imperative that you choose the correct hydraulic fluid. Each fluid under consideration has its own characteristics i.e. optimum operating conditions, viscosity, anti-wear features, and so on.

When you consider a hydraulic system, the hydraulic fluid assumes great significance. This is because the hydraulic fluid will have a far-reaching influence on performance parameters like heat dissipation, power transmission, contamination, lubrication, debris transportation, as well as sludge formation. In order to choose the best hydraulic fluid, you need to consider the requirements of the system as well as operating conditions. Additionally, you also have to take into account safety, environmental conditions, and the regulations that govern the hydraulic system’s performance.

How do hydraulic oils govern the performance of the system?

When the hydraulic system is in operation, the components of the system and the fluid blend as one, and together they will define the efficiency of the system as well as its lifespan.

If the fluid does not match the hydraulic system, the following problems occur;

  • Decreased efficiency
  • Dearth of lubrication
  • Reduced lifespan of the components
  • Sludge, varnish corrosion
  • Generation of heat

None of the above situations are conducive to optimum performance of the system. Hence if you have to choose hydraulic oil, keep the following in mind.

Monograde v/s Multigrade

The operating temperature of the hydraulic system will dictate whether you need monograde or multigrade oil. If you have a system that needs to be operated during the freezing winters as well as tropical summers then you need multigrade oil in order to maintain the viscosity of the oil within limits that are optimal, as you are taking into account the wide temperature range.

If on the other hand, the hydraulic system has a quite narrow temperature range, then you will be able to employ monograde oil in maintaining the best fluid viscosity. Multigrade oils are costly, so if you have a narrow temperature range, go for monograde oils.

Hydraulic fluid’s viscosity

Though there are other fluid properties that have a bearing on the system’s performance, the viscosity of the hydraulic fluid is a key element. If the viscosity of the hydraulic fluid is low, the film of oil will be wafer-thin and will result in the metal to metal contact, leading to friction and wear and tear of the components. Fluids with low viscosity increase the chances of internal leakages leading to low volumetric efficiency.

If the fluid viscosity is too high, the system will encounter sluggish movements as well as reduced efficiency, mechanically speaking. It will in turn cause energy losses and generate an unnecessary amount of heat. High fluid viscosity also causes poor air release, cavitation, and insufficient lubrication.

Hence, taking the above points into consideration you should opt for central hydraulic oil manufactured by a central hydraulic oil company in India. EUROLIQUIDS is a proven master in manufacturing hydraulic oils that will live up to their name and ensure the best performance of your hydraulic system.

Ordered 3 litres of Rowe 75w80 TopGear FE transmission oil. Product was promptly delivered on time. This oil is one of the few oils that mentions the original VW OEM part numbers (G052 527 A2) for 2.0 TDI manual transmission. Shift quality is as good as OEM. Overall Im happy with the product

Shubham Bhatia

Recently got my Swift Vdi serviced from Rowe oil. Really amazed to see the difference in the ride quality and improved average (25km/L). Would definitely use again and recommend everyone who wants best in class average in their cars.

Syed Razvi

My friend suggested me to use this oil, I was a little skeptical about it as I havent heard of it earlier. But then did a little bit of research online and this brand is not a new brand, it's in the international market for many years.

Faizaan Shah

Got it recommended and done by GT TUNERZ so I had to give it a try for sure. It has been the best oil til' now for me. I can feel the abrupt change in my engine power and refinement of the engine. If you love your car and want it to love you back then this engine oil is highly recommended for you.

Jagswroop Singh

Great product, Great service with pre buying assistance. Not a depth review but the vehicle feels smoother and sound better. Keep it Up, Looking forward for regular festive offers to grab good deals.

Satyam Singh

After using Rowe engine oil for the 1st time now engine is smooth, less engine noise, smooth idling. Overall good quality product.

Vaishanv Reddy

Most of these multi-brand workshops use 5w-30 over recommended 0w-20 because it's not available in entire india for diesel car

Finally I'm glad i found ROWE 0w-20 Motorsport oil with volvo certification

Hardik Doshi

The only oil with the grade which comes oem in all volvo and now im all happy n satisfied with this company to be a part of my cars shelf life...i have used it in my volvo and im really very happy with rowe oil.

Babil Salam

Used on 120000kms run C250 Cdi 2010 model Felt super smooth and less engine noise Satisfied and definitely recommended..

GT Tunerz

Fantastic oil, and more importantly, fantastic range, so one can get the correct grade for the application desired engine, gearbox, brske, you name it , they have it!

Ps: Did I say awesome pricing?

Karthik gj

Hi this karthik from infinity customz chennai , I suggested my customer to go with rowe oil after using this oil engine become instantly very refined and best performance output , now im suggesting all my customer to go with rowe products...

Ajay Kishwaha

Top class product and prompt service! Highly recommended

mohammed al attas

The best and unique motor racing oil launched and introduced in india by euroliquids india. Something like this was much needed. Made in Germany.

Kunal Doshi

Finally i found out some trustworthy and efficient oil for my BENZ. This is a brand that strictly follows OEM specifications...

Amit Yadav

Cruze vcdi 2.0 running on ROWE. Engine feels much more smoother and responsive :)


Really good review , the car feels much more smoother and peppier.

Tarun Vallabhaneni

Best Product Ever used,
Engine is more refined,
True German Engineering,
Value for money .

Atishay Jain

Used the Engine Flush and Engine Oil. Significant difference in running of the vehicle. Highly recommended!
