Car ownership Nissan Almera with a 1.6-liter power unit requires the owner to have a clear understanding of the technical nuances of maintenance. Engine H4M (or its predecessor K4M) is reliable, but extremely sensitive to the quality of lubricants and their level. Errors in selecting the volume or type of fluid can lead to a decrease in the life of the piston group and overheating of the turbine, if installed.
Many car enthusiasts make the fatal mistake of relying on average data from the Internet, without taking into account the condition of the engine and the type of gearbox. For correct operation of the lubrication system, it is necessary to know not only the nominal volume, but also the manufacturer’s tolerances, as well as the method for correctly measuring the level after draining the waste.
The exact volume of engine oil for 1.6 engines
When planning maintenance, it is important to understand that the volume declared by the manufacturer does not always coincide with the actual amount of fluid poured into the crankcase. For most modifications Nissan Almera with a 1.6 engine (102 hp or 115 hp) the situation is as follows: when changing the oil with a complete drain and replacing the oil filter, about 4.5 liters will be required.
However, if you only change the lubricant without replacing the filter, the volume may drop to 4.3–4.4 liters. If you use a cartridge filter or a metal replacement element, the amount of liquid may vary slightly. Oil pan volume is a critical parameter, since overfilling or underfilling is equally dangerous for the engine.
For cars with a CVT or manual transmission, the volume of lubricant in the engine remains unchanged, but it is worth considering that the level expands as it warms up. Therefore, topping up should be done strictly according to the regulations:
- 🛢️ Pour 4 liters from the canister.
- 🔧 Start the engine and let it run for 2-3 minutes.
- 📉 Check the level again through the dipstick after cooling.
Critical Viscosity Parameters and Tolerances
Choosing the right type of oil is as important as the quantity. H4M series engines are designed to meet European quality standards, therefore the use of unsuitable fluids may lead to clogging of the oil passages. The main requirement is compliance with the specification Renault RN0720 or API SN/CF.
Viscosity should be selected depending on climatic operating conditions. For Russian realities, where winters can be harsh, the best option is 5W-30. This indicator ensures easy starting at low temperatures and sufficient protection at high loads.
In hot climates or aggressive driving styles, use 5W-40, but this must be justified by the mileage of the car. Older engines with a lot of wear may require thicker oil to maintain system pressure.
⚠️ Attention: The use of oils with a viscosity of 0W-20 or 0W-40 without the approval of an official dealer is strictly prohibited for H4M engines, as this may disrupt the operation of hydraulic compensators and phase shifters.
There are a number of brands that have proven themselves to be reliable suppliers for Nissan Almera. Among them are original Nissan oil, as well as high-quality analogues from Total, Motul and Shell. The main condition is to purchase products from official distributors to avoid counterfeits.
- 🛡️ Always check the integrity of the packaging and hologram.
- 🌡️ Consider the air temperature when choosing the season of use.
- 📜 Save receipts and purchase documents for guarantee.
Step-by-step instructions for changing the oil
The lubricant replacement procedure is not difficult, but requires care and adherence to the sequence of actions. The first stage is to warm up the engine to operating temperature, which allows the waste to drain as completely as possible and carry the sediment with it.
After stopping the engine, you need to unscrew the drain plug of the oil pan. Be careful as the oil will be hot. Place a container for drainage and wait until the liquid stops flowing in a stream, turning into dripping.
Then you need to replace the oil filter. If you are using a metal filter, you just need to unscrew it and install a new one. In the case of a cartridge filter, be sure to replace the O-ring by lubricating it with fresh oil before installation.
☑️ Oil change instructions
New oil is poured through the neck. It is recommended to use a funnel to prevent dirt from getting into the engine. First fill in 4 liters, then wait a couple of minutes and check the level with a dipstick.
Add oil in small portions, checking the level every 200-300 ml. Overfilling is dangerous because the oil will begin to foam, which will lead to loss of lubricating properties and possible failure of the seals.
