Like many other useful things, Litol 24 came to us from the defense industry. This popular lubricant replaced universal grease, which for a long time was the only option for amateur motorists.

Litol 24 in various packaging

The first samples of the grease lubricant were called CIATIM, after the name of the specialized Institute of Aviation Oils.

In practice, this is No. 1 among universal lubricants: if it is necessary to treat any part or friction surface, the hand itself reaches for the tube with Litol.

Why is this embedded lubricant so popular among car enthusiasts? It is applied according to the “set it and forget it” principle. During its service life, no control or special protection is required - Litol simply works.

Main properties of Litol 24

In addition to the main task: lubricating rubbing parts, it can act as protection against corrosion (unless the coating strength is low).
In addition, there are other useful consumer properties:

However, there are also disadvantages:

• flammable lubricant: this requires certain conditions of storage and use;
• the composition does not contain additives that increase the wear resistance of parts;
• thick lubricant accumulates external dust, including abrasive dust;
• does not maintain the specified characteristics under welding loads.

Lubricant composition

As already mentioned, Litol 24, manufactured according to GOST 21150 87, consists of a residual base cleared of paraffins (up to 50%). We can say that the material for production is waste from the oil refining industry.

In addition, the composition includes up to 40% mineral oil. According to GOST technology, it is unacceptable to use purified waste, only “first-mined” raw materials, even the cheapest ones.

The so-called lithium soap (lithium 12-hydroxysterate) 10%-15% is used as a thickener. A small percentage of additives: antioxidant, viscosity - to increase density.

Lubricant characteristics

When purchasing, you must check compliance with GOST 21150-87. Lithium greases have features in comparison with the same grease. Check the packaging or documentation for compliance with the technical specifications.

GOST parameters are shown in the table:

In addition, Litol 24 is often used in places where metal and rubber come into contact (ball joints, oil seals, bushings, etc.). Therefore, the tolerances for exposure to rubber grades 26-44 must be observed. With prolonged contact with lubricant, hardening and swelling of soft parts should not exceed 8%.

Of course, each manufacturer can change the characteristics of Litol 24 within the framework of the standard without compromising its consumer properties. In addition, there is a technology for release according to technical conditions.

Unlike GOST standards, the TU composition is only suitable for lubricating door hinges and electrical connectors.

Application area

Like any lubricant, Litol is used where there is friction, rotation, and corrosion protection is also required. Simply put - in any mechanisms.

• sliding and rolling bearings (both embedded and open in the housing);
• any hinges, regardless of load;
• gears (except for gearboxes and transmission units);
• rack-and-pinion transmissions:
• skid surfaces of industrial machines - Litol is practically unrivaled;
• electrical contact units.

And, of course, the main application is cars.

Use as a friction reducer, only in internal cavities. There should be no contact with the external environment. This is not because the lubricant is afraid of air: it simply accumulates dust, dirt, and abrasive particles.

In friction parts this leads to increased wear: that is, work “in reverse”. For this reason, periodic replacement of lubricant in critical components is required.

Litol is also used externally, on fixed nut joints. Thanks to its water-repellent properties and good adhesion, the grease provides good protection against corrosion of threaded connections. The layer does not collapse even when exposed to sunlight.

This consumable is not at all capricious: it can be applied with a brush, a screwdriver, an old ruler, or even with your finger. The lubricant is non-toxic (no more than any petroleum product). After working with the substance, simply wash your hands with laundry soap. Of course, if it gets into your eyes, you should consult a doctor.

Remember about fire danger! Litol 24 ignites when exposed to open fire!

Competitors and analogues of Litol 24

Many people mistakenly believe that Litol can be replaced with solid oil. These are completely different materials, they are not replaceable and are not competitors.

Imported analogues:
Let’s make a reservation right away: imported lubricants have no unconditional advantages. More precisely, they exist, but these qualities are not in demand under the conditions of using Litol.

Every self-respecting manufacturer of petroleum products also produces lubricants:

This is not a complete list. If you are willing to pay for beautiful packaging and a more pleasant consistency, you can use an imported manufacturer.
