Which brand is Nissan's dedicated engine oil?

[Josephine]

Nissan's dedicated engine oil is Shell. Here is the relevant introduction about engine oil: Composition: Engine oil consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of base oil performance, endowing it with certain new properties, making them an important component of lubricating oil. Function: Between the piston and cylinder, as well as between the main shaft and bearing bush, movement inevitably causes friction, requiring engine oil to reduce frictional resistance and incidentally save energy consumption. It can flush away contaminants such as carbon deposits, sludge, and worn metal particles from engine parts through oil flow, and also adsorb corrosive substances like acidic materials and harmful gases.

I've been using Nissan vehicles myself, and the genuine OEM oil is actually manufactured by Idemitsu, a brand quite common in Japan. The Nissan ECO series available at domestic 4S stores is their product. However, Shell also produces rebranded oils for Nissan, such as the Super Fully Synthetic variant. For regular maintenance, as long as the oil meets GF-6 or API SP certification with 5W-30 viscosity, it's perfectly fine. Personally, I've used Mobil 1 EP and Castrol Edge, and truthfully, as long as they meet the manual's standards, non-OEM brands are equally reliable—just be cautious not to purchase counterfeit products.

I've been driving the Teana for five years, and every time I go to the 4S shop, they use Nissan-branded full synthetic oil. The mechanic said it's actually produced by Idemitsu, similar to the Idemitsu ZEPRO you buy on JD.com, but the 4S shop version has some exclusive additives added. For outside maintenance, I've tried Shell Helix Ultra, and I feel the engine noise is a bit quieter. The key is to look for the Nissan Matic certification label on the barrel. Some niche brands like ENEOS and Gulf have actually passed the certification as well.

From a maintenance perspective, Nissan's original oil is just a rebranded product. Currently, the mainstream choices are fully synthetic oils in 0W-20 or 5W-30 grades, with Idemitsu being the most commonly used for Japanese cars, even models like the SKYLINE use it. Alternatives such as Shell Helix Ultra or Mobil 1 are also acceptable, but make sure they meet the ILSAC GF-6 standard. For older models, semi-synthetic oils like Mobil Super 2000 are sufficient. The key is to check the certification number required in the maintenance manual, which is more important than the brand.

According to the Nissan technical manual, the engine oil must meet API SN or higher certification. The original factory oil typically uses the Nissan ECO series produced by JXTG Group (now called ENEOS). For alternative brands, it is recommended to choose fully synthetic oils with a viscosity of 5W-30, such as Castrol EDGE Stop-Start or Total Quartz 9000. A reminder for new vehicles equipped with a particulate filter: low-ash engine oil must be used to avoid clogging. It's best to check the certification standards corresponding to the vehicle model and year.

At maintenance shops, the most commonly used oil for Nissan vehicles is Idemitsu 0W-20 full synthetic. This oil is relatively thin, fuel-efficient but consumed quickly. For older cars, it's recommended to use 5W-30, with Mobil or Shell being more durable. Turbocharged vehicles require full synthetic oil, and engines like the QR25 are particularly picky about oil. Recently, ENEOS (formerly Nippon Oil) SUSTINA series has also been found to perform well, but make sure to check if the barrel has Nissan's certification code. The key isn't chasing OEM products but choosing the right specifications.
