Diesel Tiller Oil

tiller, as well as any technical device, requires careful operation and periodic maintenance. Oil is a key factor in ensuring full engine performance. But it is necessary to deal with oils, their types, feature replacement and possible problems.

Which oil is better to pour into the diesel engine tiller?

Naturally, a correct recommendation is the option that is specified in the instruction manual. You should carefully study the document and follow the described points.

But if the necessary information has not been obtained, one should understand the species represented on the market today. According to the classification of the American Petroleum Institute, according to the operational categories, oils for diesel engines are divided into such classes as:

  • API CJ-4. It was created specifically for powerful devices 10-12 litres. s., which are constantly subjected to severe stress. The oil is fully compliant with current regulations on emissions of NOx and particulate matter for engines produced in 2007. It should be noted that limits for certain indicators are introduced for CJ-4 oils: ash content less than 1.0%, sulphur 0.4%, phosphorus 0.12%;
  • API CI-4. This type is relevant for engines with various types of pressurization and injection. It is characterized by increased resistance to thermal oxidation and is known for its high desperate properties;
  • API CH-4. Such oil is exploited for four-stroke engines operating on diesel. It fully complies with the most stringent requirements of American and European manufacturers. Oil is less sensitive to fuel containing more than 0.5% sulphur, which is a significant advantage;
  • API CF-2. This option is ideal for tillers with two-stroke engines used in difficult conditions. The oil contains additives that protect the internal parts of the engine from rapid wear;
  • CA API. Suitable for a tiller, operating on low-sulphur diesel fuel (low and medium voltage, not suitable for high mechanical stresses). It protects against the formation of harmful deposits;
  • API cv Ideal for sour fuel engines. Significantly reduces the possibility of bearing corrosion;
  • API CC. The oil is suitable for turbocharged engines but without superchargers. Withstands high voltages and is a reliable protector for parts.

If you classify these substances by viscosity (SAE), you can display all the features on a special scheme and briefly supplement it with the following information:

  • The letter “W” denotes those types of oils that can be used in harsh winter conditions (SAE 0W, 5W, 10W, 15W, 20W, 25W);
  • The absence of the letter designation is accompanied by highly viscous species that are ideal for summer (SAE 20, 30, 40, 50, 60);
  • All-season are the most common and versatile, so they are indicated by a double combination (5W-30, 10W-40, etc.).

Often, oils for winter and summer are marked by different numerical values, in winter with lower (increased viscosity), and in summer with greater. Oil for diesel tillers with air cooling and without should just be selected for viscosity, because if you make the wrong choice, the lubricant will stick and stay on the cylinder.

Oil change: how to do

First you need to check the oil level by unscrewing the filler plug of the engine crankcase. An important point: between the maximum and minimum mark on the dipstick, there should be an oil trace, and if it is absent, it should be wetted to the middle.

The replacement procedure is quite simple:

  • To begin with, the tiller should be placed in a horizontal position;
  • Then you need to remove the plug on the drain tank (you can use a screwdriver);
  • The next step is the need to patiently drain the entire contents of the tank into a container with a capacity of at least 2 litres (the process takes 15-20 minutes) and tighten the cap;
  • Now you can very carefully pour fresh oil to a certain point without spilling it.

An important fact: in the newly purchased tillers, on air-cooled and non-air cooled engines, it is necessary to change the oil after the first 5 hours of operation, then this procedure should be carried out after every 25 hours of operation. Experienced owners of this technology carry out the process before each spring.

What are the reasons why diesel tiller takes a lot of oil?

Sometimes there are situations when not everything goes as smoothly as you would like with tiller. Among the causes of this problem are:

  • PCV system malfunction, due to which the oil is sucked back into the engine. To get rid of the trouble, replace the PCV valve;
  • Mechanical problems can also cause excessive “absorption” of the oil. It is necessary to check the compression, because, due to its poor performance, the oil may not get into the combustion chamber, but “disappear” along with the fuel;
  • Previously occurring problems with a damaged catalytic converter can also cause. It is possible that dust and particles of scattered catalyst got into the combustion chamber and caused mechanical damage to the cylinders. The solution is cylinder replacement;
  • Worn valve seals allow the oil to sleep through the engine quietly, so you should carefully check them and update them if necessary.

The tiller engine is the “heart” of the device, so the choice of oil and care for it should be taken with the utmost seriousness, then the unit will “thank” the careful owner for a long service and the minimum number of malfunctions.
