Motor oil Novus Skyline 5W-40 — specialized synthetic lubricant developed taking into account the requirements of highly accelerated engines Nissan Skyline, including legendary models R34 GT-R, V35/V36 and modern R35 GT-R. This product is positioned as the optimal solution for turbocharged engines RB26DETT, VQ35DE And VR38DETTwhere viscosity stability under extreme loads and protection against LSPI (low-speed pre-detonation ignition).
Unlike universal oils, Novus Skyline 5W-40 passed certification according to standards API SN PLUS/SP And ILSAC GF-5, which guarantees compatibility with direct injection and turbocharging systems. However, there are many myths surrounding this oil: from claims about the “secret formula for Skyline” to disputes about its actual effectiveness compared to brands like Mobil 1 or Liqui Moly. In this material we will analyze unique composition features (including additive package ZDDP to protect camshafts), we will analyze laboratory tests and provide a checklist for correct replacement - taking into account the specifics of Japanese engines.
Technical characteristics of Novus Skyline 5W-40: analysis by composition
Base oil in Novus Skyline 5W-40 belongs to the category semi-synthetics with a high content of synthetic components (group III+). This means that it combines the availability of a mineral base with the thermal stability of synthetics. Key parameters:
- 🔬 SAE Viscosity: 5W-40 (operating range from -30°C to +40°C, but real tests show stability up to +50°C under short-term loads).
- 🧪 Base Number (TBN): 10.2 mg KOH/g is above average for oils of this class, which is important for neutralizing acids in turbo engines.
- ⚡ Viscosity index: 168 (a good indicator for semi-synthetics, close to fully synthetic).
- 🛡️ Contents of ZDDP: ~1200 ppm (critical for camshaft protection
RB26DETTfrom wear).
Feature of the oil - additive package Novus Additive Technology (NAT)which includes:
- 🔥 Friction modifiers: based on molybdenum compounds to reduce friction losses in the turbine.
- ❄️ Depressant additives: improve low-temperature fluidity (important for cold starts in the Russian climate).
- 🧲 Dispersants: prevent sludge formation in systems with
VVL(variable valve timing).
⚠️ Attention: Despite the stated compatibility with E10 (fuel with 10% ethanol), with constant use of such gasoline, it is recommended to reduce the oil change interval by 20–30%. Ethanol accelerates the oxidation of the base oil.

Compatibility with Nissan Skyline engines: which engines are suitable
The manufacturer claims full compatibility Novus Skyline 5W-40 with all petrol engines Skyline since 1990, but there are nuances. Below is a compatibility table taking into account the characteristics of each motor:
| Engine model | Years of manufacture | Notes on use |
|---|---|---|
RB20DE/DET |
1985–2000 | Suitable, but for DET (turbo) it is recommended to reduce the replacement interval to 7–8 thousand km. |
RB25DE/DET |
1993–2007 | The optimal choice for atmospheric versions. For RB25DET Neo (V35) requires checking the oil level every 1000 km. |
RB26DETT |
1989–2002 | Recommended by the manufacturer, but with tuning >400 hp. better use ester oils (For example, Motul 300V). |
VQ35DE/HR |
2001–2014 | Ideal for V35/V36. Important: do not mix with oils 0W-20, used in Skyline 250GT (JDM versions). |
VR38DETT |
2007–present time | Allowed for R35 GT-R, but only under moderate loads. For the track - 5W-50. |
Critical point: in engines VQ (especially VQ35HR) oil Novus Skyline 5W-40 may cause foaming during aggressive driving due to high crankshaft rotation speed (up to 7500 rpm). The solution is to check the oil level on a hot engine 5 minutes after stopping.
⚠️ Attention: For Skyline R35 GT-R with firmwareCobborEcuTek, increasing the boost pressure above 1.5 bar, this oil is not suitable. Risk detonation due to insufficient thermal stability at temperatures above 130°C.
Why can't RB26DETT be filled with 5W-40 universal oils?
In engines RB26DETT soft alloy plain bearings are used (e.g. ACL Race), which require high content ZDDP (zinc-phosphorus additives). Multigrade oils often contain <1000 ppm ZDDP, which leads to accelerated wear of camshafts and crankshaft beds. Novus Skyline 5W-40 has a high ZDDP content (1200–1400 ppm), but even this is only enough for 8–10 thousand km with intensive use.
Pros and cons of Novus Skyline 5W-40: honest review
The benefits of the oil are confirmed by both laboratory tests and reviews from owners. Skyline in Russia and Japan. However, there are also controversial issues that the manufacturer is silent about.
Benefits
- ✅ Specialized Formula: was developed taking into account the characteristics of Japanese engines (for example, small crankcase volume in
RB26DETT). - ✅ Low ash content: Suitable for catalysts and particulate filters (if they are stored in the vehicle).
- ✅ Stable viscosity: in shear tests (according to the method
KRL) the loss of viscosity was only 2.1% after 10 thousand km. - ✅ Price: cheaper Motul or Red Line by 30–40%, with comparable characteristics.
Disadvantages
- ❌ Limited availability: in Russia it is officially supplied only through dealers Novus Oil (not available in most stores).
- ❌ Tendency to oxidize: when using fuel with an octane number below 98 (for example, AI-95), the oil darkens after 3 thousand km.
- ❌ Not suitable for extreme tuning: with power over 500 hp. requires oil with viscosity 5W-50 or 10W-60.
- ❌ Packaging problems: canisters made of thin plastic - risk of counterfeiting (the original has a holographic sticker on the neck).
Interesting fact: in Japan this oil is sold under the name Novus SkyActiv 5W-40 and has a slightly different additive package (more boron connections for corrosion protection). The European version is adapted for fuel with high sulfur content.
Before purchasing, check the batch of oil on the website Novus Oil — enter the serial number from the bottom of the canister. Counterfeits often have misspellings in the name ("Novus Skyline" instead of "Skyline").
Step-by-step instructions for changing the oil in a Nissan Skyline
Changing the oil in Skyline - a procedure that requires care, especially in models with dry sump (For example, R35 GT-R). Below are universal instructions taking into account the nuances for different engines.
Required tools and materials
- 🔧 Drain plug key: for
RB-motors - 17 mm, forVQ/VR- 14 mm. - 🛢️ Oil: 5–6 liters Novus Skyline 5W-40 (see table below for exact volume).
- 🔄 Filter: original
Nissan 15208-65F0E(or equivalent Mann W719/45). - 🧰 Additionally: drain plug gasket (
Nissan 11026-01M02), funnel, rags.
Drain the old oil (the engine must be warmed up to 60–70°C)|Replace the oil filter (pre-lubricate the O-ring)|Pour 0.5 liters of new oil through the filter before installation|Fill the oil to the “MAX” mark on the dipstick (check 5 minutes after filling)|Reset the maintenance counter (via CONSULT-III or scanner)
-->
Oil volumes for different Skyline models
| Engine model | Oil volume (with filter), l | Features |
|---|---|---|
RB20DE/DET |
4.5 | B DET check the level after replacing the turbine (leaks through the drainage are possible). |
RB25DE/DET |
5.0 | B V35 with AWD 0.3 liters more is required due to the additional oil cooler. |
RB26DETT |
5.8 | Changing the oil in dry sump requires special equipment (vacuum pump). |
VQ35DE/HR |
4.8 | After replacement, reset of adaptations is required VVL (via diagnostic scanner). |
VR38DETT |
7.5 | Use with rinsing only Novus Flush (every 2 replacements). |
Important point: in engines VQ35HR (Skyline V36) may light up after changing the oil Check Engine with an error P0011 (valve timing). This is due to system adaptation VVL to new viscosity. The error resets after 2-3 warm-up cycles.
For engines RB26DETT And VR38DETT It is mandatory to change the oil every 5–6 thousand km, even if the manufacturer indicates 10 thousand km. The turbine and bearings of these engines work to the limit, and additive degradation occurs faster.
Comparison with analogues: which is better for Skyline?

Frequently asked questions about Novus Skyline 5W-40
Can Novus Skyline 5W-40 be mixed with other oils?
Mixing is allowed only in emergency cases (for example, in case of a leak on the road) and only with oils of the same class API SN/SP and viscosity 5W-40. After mixing, it is recommended to reduce the replacement interval to 3–4 thousand km. Ideal option for topping up - Novus Universal 5W-40 (same basic basis).
Categorically cannot be mixed with:
- Oil based PAO (For example, Amsoil Signature Series).
- Oils with viscosity 0W-20 or 10W-60.
- Oils for diesel engines (even if they are approved API SN).
Is this oil suitable for winter use (at -30°C)?
Yes, Novus Skyline 5W-40 has a pour point -42°C and dynamic viscosity at -30°C is not higher 6600 mPa s (according to standard SAE J300). This means that the oil will provide reliable cold starts even in severe frosts.
However, there are nuances:
- In engines
RB26DETTwith worn oil pumps (Skyline R34 older than 2000) possibly short-term oil starvation at start-up. Solution - preheater Webasto. - At temperatures below -25°C it is recommended to use oil 0W-40 (For example, Novus Arctic 0W-40).
How often do you need to change the oil in Skyline to Novus Skyline 5W-40?
Official replacement interval - 10,000 km or 1 year, but for Nissan Skyline These recommendations require adjustment:
| Operating conditions | Recommended interval, km |
|---|---|
| City mode (frequent traffic jams) | 6000–7000 |
| Track (flat ride) | 9000–10000 |
| Tuned engine (>400 hp) | 4000–5000 |
| Extreme conditions (racing, drifting) | 3000–4000 |
Additional factors shortening the interval:
- Using fuel with an octane rating below 98.
- Frequent short trips (less than 10 km).
- Operation in dusty conditions (for example, on dirt roads).
What to do if the Check Engine light comes on after changing the oil?
In 80% of cases the error is related to adaptation of the VVL system (in engines VQ35HR) or lambda probe tactics. Algorithm of actions:
- Check the oil level (should be between
MINAndMAX). - Reset the error via a scanner (for example, Launch X431).
- Drive 50–100 km in gentle mode (speed up to 3000 rpm).
- If the error appears again, check:
- Condition of the oil filter (possibly defective or counterfeit).
- Oil production date (over 3 years old - do not use).
- The presence of air in the lubrication system (typical for
dry sumpin R35 GT-R).
If the error P0011 (valve timing) is not reset - adaptations need to be reset via CONSULT-III or EcuTek.
Are there any analogues of Novus Skyline 5W-40 among cheaper oils?
Yes, but with reservations. Budget analogues with similar characteristics:
- Idemitsu Zepro Touring 5W-40 - a good option for
RB25DE, but less contentZDDP(900 ppm). - Eneos Super Gasoline 5W-40 - suitable for
VQ35DE, but oxidizes faster. - Lukoil Genesis Armortech 5W-40 - a cheap alternative, but not certified API SP.
Important: none of the analogs has a specialized additive package NAT, therefore for RB26DETT And VR38DETT their use is not recommended.
