Introduction:
The processing requirement for bio-based alternatives to mineral products has long damaging green-house gas emissions from

Methodology:
The extraction of Neem oil is a complex process and there are several methods used to extract the oil from the seeds.These include mechanical pressing, cold press process.which is the most common method, solvent extraction, and steam pressure extraction.Each method has its own advantages and disadvantages, and it is important to choose the right method for the desired application.
Cold Press Method: 1. Harvesting Neem seeds: The seeds of the neem tree (Aza-dirachta-Indica) are used to obtain neem oil.It should be in dry condition before using for the process.

Graphite
A beneficial fluid has minimal contact between its component parts and the walls of the vessel in which it is housed.The fluid's total viscosity index was boosted by using graphite particles dissolved in methanol as a friction modifier.Graphite also serves as an anti-wear agent in the composition.

Mono ethylene glycol:
It is not desirable for brake or clutch fluids to freeze in the hoses orpipelines, as this Make use of a coldpress extraction machine.These machines are designed to extract oil at low temperatures yet maintain the oil's inherent characteristics intact.Set up and activate the machine exactly to the manufacturer's instructions.Place the neem seeds in the machine's hopper.

Collection of oil
The oil extracted by the machine will be collected in a separate container.Assemble a clean and dry container to collect the neem oil.Straining may cause the force transmission to fail.Even as temperature change brake fluids must retain a low amount of compressibility .when the brake pedal is depressed the brake caliper piston force should working temperature adding contaminating moisture into the fluid mass on cooling to function as both an antifreeze and a coolant a small amount of monoethtleneglycol lubricant which is also soluble in most organic solvents was added to added to the formulation recipe.

Detergent:
Detergent oils emulsify water and distribute and suspend other pollutants such as varnish and sludge.This keeps components free of deposits, but it also means that pollutants do not settle out and must be provided in proportion.Fluid cooling is critical because the fluid may boil in its pots at very high.These can be desirable qualities in mobile hydraulic systems, which, unlike industrial systems, have minimal chance for settling 2. Appearance and odor -Amber with a pungent/garlic Oduor 3. pH value -5.0 to 6.0 4. Freezing Point -46.4°F(8°C) 5. Boiling Point -347°F (175°C) 6. Flash Point -200°F (93.3°C)

Procedure: 1. Neem oil selection
Choose high-quality, cold pressed neem oil for the base.Ensure that the neem oil is free from impurities.

Measurement of Oil quantity
Determine the required quantity of neem oil based on the desiredvolume of hydraulic oil.Use agraduated cylinder or anotherprecise measuring tool 3. Add graphite Measure the appropriate amountof graphite powder.Graphite is added to improve lubrication properties.The amount will depend on the volume of neem oil, and it's typically added in small proportions.

Incorporate Monoethylene Glycol
Measure the desired quantity of monoethylene glycol.This additive is commonly used in hydraulic fluids to improve low-temperature properties.Adjust the amount based on the desired characteristics of the hydraulic oil.

Introduce detergent
Measure the required amount of hydraulic oil detergent additive.This helps in and precipitation of impurities at the reservoir due to its tiny volume.The fundamental issue with these fluids is that they have good water emulsifying capacity, which means that if water is present, it is not separated out of the fluid.
Water accelerates the ageing of the oil, lowers lubricity and filterability, shortens seal life, and causes corrosion and cavitation.Emulsified water can be converted to steam in highly loaded areas of the system Physical and Chemical Properties of Neem Based Oil 1. Physical state -Liquid maintaining cleanliness by dispersing and suspending contaminants.Adjust the quantity based on the specific detergent used and the desired cleaning properties.

Storage
Store the neem-based hydraulic oil in a clean, dry, and sealed.

Viscosity Measurement
Measure the viscosity of the neem-based hydraulic oil using a viscometer.Adjust the viscosity by adding more neem oil or additives as necessary to meet the desired specifications.

Filtration
Filter the hydraulic oil to remove any remaining particles or impurities.This step is crucial for ensuring the cleanliness of the final product.02 shows the comparison of the viscosity of Neem based hydraulic oil, neem base oil and hydraulic oil (DOT 3).Monoethylene glycol acts as both an antifreeze and a coolant.A solid or block substance cannot be employed as a fluid, and extremely high temperatures are hazardous in fluid operations because they generate unwanted moisture in fluid pipes and lines.Neem seed oil is less likely to harm system components and has better freezing and saponification capabilities.Within the allowable range of viscosity.Furthermore, the qualities of the neem seed oil provided in table 3 and compared with other values from literature, which are in close agreement, indicate that the extracted neem seed oil is a true sample representation.
It may show that, Lubricants and additives give fluids performance characteristics Detergent oils emulsify water while also dispersing and suspending pollutants like varnish and sludge.This prevents deposits on components, but it also means that pollutants do not settle out and must be filtered away.These can be desirable qualities in mobile hydraulic systems, which, unlike industrial systems, have minimal opportunity for contaminants to settle and precipitate at the reservoir due to its tiny volume.The fundamental issue with these fluids is that they have great water emulsifying capacity, which means that water is not separated out of the fluid if it is present. of its qualities.The results demonstrate that the it will improve its applicability and appropriateness for use as braking fluid.The neem seed oil brake fluid is recommended for usage in automobiles to test its efficiency, and further research is also advised in order to improve on its properties by producing a better brake formulation, which will increase its application.Primary parameters that determine the appropriateness of any hydraulic fluid.The combustion of bio-based substances generates fewer greenhouse emissions than petroleum-based compounds.This outcome safeguards our ecosystem against pollution and its negative consequences.From our project we have concluded that, boiling point and the viscosity of neem based hydraulic oil is more than DOT 3 hydraulic oil.The study presented in this paper explores the potential of neem oil as a sustainable alternative to mineralbased hydraulic fluids.The researchers formulated a neem-based hydraulic oil by adding various additives to achieve the desired fluid characteristics.The use of neem oil as a base substance for hydraulic fluids could help reduce the environmental impact of hydraulic fluids, which can have a significant impact on the environment.The findings of this study contribute to the ongoing exploration of eco-friendly hydraulic oil for industrial applications.Further research is needed to explore the full potential of neem oil as a sustainable alternative to mineral-based hydraulic fluids.

Cleaning and drying: Remove any contaminants or debris from the neem seeds.Allow the seeds to completely dry to reduce moisture content.3. Pressing: After finishing the extraction, filter the oil to eliminate any leftover seed particles.For this, you can use cheesecloth or muslin material.Pour the oil through the cloth over the collection container.4. Storage: To keep the extracted neem oil safe from light, store it in a dark glass bottle.Light exposure might impair the oil's quality.Keep the oil cool and dark, away from direct sunlight.
