Dielectric candle grease, i.e., non-conductive current, is designed to protect insulation from breakdown during car operation. In a modern car, more than 400 contacts. The operation of all electrical systems depends on their serviceability. All devices are consumers of current, which is transmitted to them from the battery and generator through insulated wires. Accordingly, to ensure the smooth operation of electrical appliances and their conductors, care must be taken to ensure reliable protection of this insulation itself, namely, dielectric grease for it. This is especially true for old cars or for very humid climates.
Advantages of various types
Dielectric greases for spark plugs are produced in the form of a spray or a jelly-like mass in tubes. This allows you to apply the exact amount of the substance, and in those places where it is necessary. The required amount of lubricant in this case is provided by the measuring cap with which the tube is twisted. It is more convenient to apply the tool in the form of a spray on the wires, since it can be sprayed even in hard-to-reach places.
Today on the market there are a huge number of different dielectric greases. How not to make a mistake and choose the most suitable? Let's consider some of them.
Optimal options
Molykote 111 is recommended by such automotive giants as BMW, Jeep, Honda. This grease has probably the longest duration. It protects against moisture and provides excellent electrical insulation. There is a significant drawback - this is its high price.
Dowsil 4 - This product is mainly used for waterproofing and electrical ignition. The grease has a silicone base. Dowsil 4 is a budget and very common option for reliable isolation of the ignition system.
BERU ZKF 01 is a sealant that is applied inside the tip or on the candle insulator. If the parts to be processed are made of rubber, this grease is what you need. It goes well with silicone insulators without destroying them. Great for such materials.
Mercedes Benz Lubricating Grease is designed for premium cars. It is delivered under the order from Germany. On sale in the retail network it is not.

And this is just a small list of all these products designed to ensure the smooth operation of your car. In fact, there are many more.
An ideal sealant must necessarily have the following properties:
- Withstand strong stress.
- It is good to interact with the insulating material, not to cause its damage, not to cause damage.
- To be absolutely tight and able to reliably protect the insulation from breakdown during engine operation.
- Resist temperature changes.
- To be convenient to use in garage conditions (relevant for car enthusiasts who prefer to independently carry out maintenance of their car).
