Here's a ranking of the top rated products in this category. To give you a quick overview, we've also added some key information about the products.
1. Robbyrob Distilled water
This distilled water in a practical 1-litre bottle is the perfect basis for a water cooling circuit. The distilled water is deionised, UV-irradiated and chemically pure. It is therefore absolutely pure water that leaves no limescale or other deposits in the water circuit. It is of course possible to add colourants, biocides or other additives to the water.
Features of distilled water:
- Deionised, UV-irradiated & chemically pure
- Complies with DIN 13060, DIN 43530 & EN 285
- In the practical 1 litre bottle
Highest purity enables many applications. Distilled water is indispensable for high-end PCs with (custom) water cooling. Its chemical purity is verified by DIN 13060, DIN 43530 and EN 285. Without deposits, water cooling lasts significantly longer and cools better. The low electrical conductivity is also an advantage.
Nevertheless, there are many other ways to utilise pure water. It is also indispensable in the household, car, laboratory and cosmetics. The advantage that distilled water leaves no residue is also of enormous importance here. It can therefore also be used in steam irons, humidifiers, radiator evaporators, for spraying or watering houseplants. In cars, it is used to fill the car battery, for the windscreen washer system or the car radiator. Distilled water is even useful in laboratories, beauty parlours and aquariums.
Technical details:
- Number of bottles: 1
- Content: 1 litre per bottle
- Colour: Clear.

2. Motorex Brake Fluid DOT 5.1
Brake Fluid DOT 5.1 is a brake fluid for hydraulic brake and clutch systems with a boiling point of at least 260 °C and an extremely high wet boiling point of at least 180 °C. Due to its low low-temperature viscosity, it is particularly suitable for additional components such as ABS and ASR. It prevents vapor bubble formation even under extreme loads and ensures optimal braking performance as well as precise responsiveness. Contains 250 ml of brake fluid.

3. Liqui Moly CERATEC ceramic wear protection 3721 300 ml
High-tech ceramic wear protection reduces friction and wear through chemical and thermal high-load ceramic connections. It prevents direct metal-to-metal contact, thus increasing the service life of aggregates. Additionally, it reduces fuel consumption of gasoline and diesel engines thanks to a smooth running effect. This product is miscible with all commercially available engine and automotive transmission oils.

4. Robbyrob Water equivalent to distillate
Fully desalinated and demineralized by ion exchange. Suitable for car, household, hobby, and laboratory use. Not for consumption. Not suitable for medical purposes. Store dry and protect from light. Use only from the original bottle or lid. Made in Switzerland.

5. Liqui Moly Power Steering Oil Loss Stop 1099 35 ml
The included additives optimally care for rubber and plastic seals in the steering gear. They prevent oil loss, stop oil leakage in dripping steering gears, and regenerate hardened seals. The boreholes and channels of the steering gears are cleaned, refreshing the oil's performance. Noise generation is reduced, lifespan is extended, and repair costs are lowered. Suitable for steering gears filled with ATF II, ATF III, ATF VI, or central hydraulic oils. 35 ml is sufficient for 1 liter of oil volume.

6. Liqui Moly Oil loss stop
Description Regenerates rubber and plastic engine seals such as shaft seals, valve stem seals and prevents oil stains under the vehicle. Counteracts oil dilution. Reduces engine noise and oil consumption through piston rings and valve guides. Properties prevents smoke formation dampens engine noises maintains and regenerates rubber and plastic seals reduces oil consumption prevents oil stains and environmental pollution Application One 300 ml can is sufficient for up to 5 l of engine oil. It can be added at any time, after addition warm up the engine. The sealing effect occurs only after approx. 600 - 800 km. To ensure long-term success, we recommend using the product again every 30,000 km as a preventive measure. Note Not suitable for motorcycles with wet clutch.

7. Liqui Moly Anti-bacteria diesel additive
Highly effective biocide with a broad spectrum of activity against bacteria, yeasts and moulds. Ideally suited for preventive use in diesel vehicles that have been out of service for a long time or are little used, e.g. construction machinery, commercial vehicles, mobile homes, passenger cars, storage tanks, etc., as well as for disinfecting already infested tank systems. Use biocidal products carefully. Always read the label and product information before use.

8. Sonax Summer windscreen cleaner Ocean
The Sonax Summer Windshield Cleaner Ocean is a high-quality vehicle fluid specifically designed for the summer months. With a capacity of 3 liters, this ready-to-use windshield cleaner provides an effective solution for cleaning vehicle windows.

9. Liqui Moly Radiator sealant
Small leaks caused by stone impact, porous solder joints, or hairline cracks in the cooling system of water-cooled engines are difficult to locate, as one only notices the decreasing coolant level. This dispersion seals such leaks completely and immediately, protecting the combustion chamber from damage due to coolant ingress. It is compatible with all common coolant additives and antifreezes and can also be used preventively.

10. Liqui Moly Diesel system maintenance
Description: A combination of active ingredients with a high content of lubricity improvers and cleaning additives. This product has been specifically tailored to meet the requirements of diesel technology, such as common rail and pump-nozzle high-pressure injection, as well as low-sulfur diesel fuels, to protect these vehicles from wear. Additional active substances with cleaning, dispersing, and material-protecting properties ensure the maintenance of function in highly precise injectors. By increasing the ignition readiness, the fuel burns better during cold operation, reducing the odor nuisance from exhaust gases. It ensures optimal combustion of the fuel and reduces soot formation, thereby extending the lifespan of diesel particulate filters. Features: optimizes engine performance, catalyst-tested, good corrosion protection, oxidation-stable, prevents the sticking and gumming of nozzle needles.
