What is Kix 5W40 PAO oil: composition and production technology
Oil Kix 5W40 PAO belongs to the category full synthetic lubricants produced using hydrocracking technology with the addition of polyalphaolefins (PAO). This combination provides viscosity stability over a wide temperature range - from -35°C to +150°C, which is critical for modern engines with a high degree of boost.
Features of the composition:
- 🧪 Basic basis: a mixture of PAO (up to 30%) and hydrocracking components, which gives the oil high thermal-oxidative stability.
- 🛡️ Additive package: includes detergent, dispersant and antioxidant additives that meet the standard API SN.
- ⚡ Energy saving properties: low coefficient of friction due to PAO components, which reduces power loss by 3–5% compared to mineral oils.
The manufacturer states that Kix 5W40 PAO tested for compatibility with exhaust gas aftertreatment systems (including particulate filters DPF), however official certificates from Nissan or Renault oil doesn't have it. This means that its use does not void the warranty, but does not guarantee 100% factory compliance.

How to distinguish original Kix 5W40 PAO oil from a fake
The market for counterfeit oils is growing, and Kix 5W40 PAO was no exception. Counterfeits are often diluted with a mineral base, which leads to premature engine wear. Here are the key features of the original:
External differences of the canister:
- 🖼️ Label: Holographic Logo Sticker Kix, which changes color when tilted.
- 🔢 Barcode: must match the data on the site
kixoil.ru(check via mobile app). - 🔳 Cover: The original has a security ring marked "SEAL" that breaks when first opened.
Physical properties of the oil:
- 💧 Color and consistency: the original has an amber tint and fluidity like honey when
+20°C. Counterfeits are often cloudy or too runny. - 🧴 Smell: The original has a light chemical aroma without any harsh impurities (counterfeits can smell like diesel fuel or smoke).
If you doubt the authenticity, do a quick test: drop oil on paper and wait 2 hours. Original Kix 5W40 PAO forms a uniform spot without a dark halo. The fake leaves a clear boundary between the center and the edges.
⚠️ Attention: Counterfeit oil can cause sludge to form in the engine after 3,000 km mileage Signs: increased timing noise, black carbon deposits on the spark plugs, drop in oil pressure at idle speed.

Instructions for changing Kix 5W40 PAO oil in Nissan
Changing the engine oil Nissan using Kix 5W40 PAO does not differ from the standard procedure, but there are several nuances associated with the characteristics of this oil. Let's look at the process using an example Nissan Qashqai J11 with motor MR20DD.
Required tools and materials:
- 🔧 Key for the drain plug (usually on
14 mm). - 🛢️ Oil filter: original
Nissan 15208-9F60Aor an analogue (for example, Mann W712/75). - 🧰 Funnel and capacity for processing (minimum
5 l). - 🧴 Flushing oil (optional if switching from another type of lubricant).
Step by step instructions:
- Warm up the engine to operating temperature (
80–90°C) - this will ensure complete drainage of the waste. - Unscrew the drain plug (be careful - the oil is hot!) and drain the old oil into a container.
- Replace the oil filter. Before installing a new filter, apply a thin layer Kix 5W40 PAO onto the rubber o-ring.
- Screw the drain plug with a new sealing ring (tightening torque -
35–40 Nm). - Fill in
4.5 loil through the filler neck, then check the level with a dipstick (should be between the marksMINAndMAX). - Start the engine and let it run
3–5 minutesat idle speed. Check for leaks.
If you are switching from oil of a different viscosity (for example, 5W30), it is recommended to use flushing oil or reduce the first change interval to 5,000 km.
When changing oil in engines with a timing chain drive (for example, MR20DD) Avoid high pressure washes - they can damage the seals.
