In winter, when temperatures drop below zero, thick oil can cause the engine to fail when starting. Synthetic base Maxima Diesel LA 5W-30 remains fluid even in severe frosts. This provides immediate lubrication to critical components such as the camshafts and piston group, minimizing wear during cold starts.
For owners of pickup trucks and SUVs who often use their equipment to tow trailers or drive off-road, the oil's performance under high loads is important. The product has a high viscosity index, which allows it not to liquefy under load and maintain a protective film on friction surfaces. This extends engine life and reduces fuel consumption.
Reduced mechanical noise and vibration of the engine is a direct result of using high-quality lubricant with effective anti-wear additives. You will notice that the motor operation has become quieter and smoother after the first replacement.
Replacement procedure and maintenance recommendations
Changing your oil is a routine but critical procedure for maintaining engine health. Before starting work, you need to prepare tools and new oil. Make sure you purchase the correct amount of fluid, usually specified in the owner's manual. You should not save on a filter, as a low-quality filter can negate all the benefits of expensive oil.
The replacement procedure should be performed on a warm engine so that the old oil comes out as completely as possible. Unscrew the drain plug and let the oil drain for 10-15 minutes. After this, replace the oil filter, after lubricating the O-ring with new oil. Tighten the drain plug to the recommended torque.
Before you start replacing, do the following:
☑️ Preparing for an oil change
Pour new oil through the filler neck, using a funnel to avoid spillage. Check the level with a dipstick after a few minutes, allowing the oil to drain into the pan. The level should be between the MIN and MAX marks. Run the engine for a few minutes, then check the level again and top up if necessary.
Don't forget about replacement times. Even the highest quality oil loses its properties over time due to oxidation and contamination by combustion products. Recommended replacement interval for Maxima Diesel LA 5W-30 is 10,000 – 15,000 km or once a year, whichever comes first. In conditions of frequent trips around the city, it is better to reduce the interval to 8,000 - 10,000 km.

Common misconceptions and myths about motor oils
There are many myths surrounding the topic of motor oils that can mislead car owners. One of the most common myths is that the more expensive the oil, the better it is. In fact, quality is determined by compliance with manufacturer specifications, not price. Maxima Diesel LA 5W-30 proves that reliable protection is available at a reasonable price.
Another misconception concerns mixing oils of different brands. While this is technically possible in an emergency, it is not recommended to do this regularly. Different additive packages can react and reduce the effectiveness of the lubricant. If you decide to change the brand, it is better to perform a complete oil and filter change, and not just top up.
Also, many people mistakenly believe that synthetic oil cannot be used in older engines. This is not entirely true. If the engine doesn't have major sealing or leaking problems, a quality synthetic such as Maxima Diesel LA 5W-30, will help clean it of deposits and extend its service life. However, if there are severe leaks, it is worth consulting a mechanic.
It is important to understand that “black” oil after replacement is not always a sign of poor quality. On the contrary, this indicates that the detergent additives are working and flushing carbon deposits out of the engine. If you are changing your oil for the first time after using another product, the color may be very dark, which is normal.
⚠️ Attention: Do not use oils with a viscosity different from that recommended by the manufacturer just for the sake of saving money. Incorrect viscosity can lead to overheating or insufficient lubrication of engine components.
⚠️ Attention: Avoid buying oils on tap or from unverified sellers. A fake may contain dangerous impurities that can damage an engine within several thousand kilometers.
