Permian engine oils have been associated for decades with reliability and adaptability to Russian realities, from harsh climates to variable fuel quality. For boat owners, the choice of oil often becomes a headache: on the one hand, imported brands promise advanced technologies, on the other, domestic products benefit in price and availability. Mercury Premium or Yamalube For oil from Perm?

In this article, we will understand what oils Perm Oil Refinery (PNOS) produces, how to classify them according to standards. API and JASOAnd how well they fit two-stroke and four-stroke outboard motors, and we'll focus on compatibility with modern engines. Tohatsu, Honda BF domestically vortex/NevskyAnd we're going to debunk the myths about the "all-season" of Permian oils, and at the end, we're going to have a performance comparison table and answers to some of the questions that we're asking from the water engineers.

What is Permian Motor Oil and Who Produces It

Under the term β€œPermian engine oil" usually means products Perm Oil Refinery (PNOS) One of the largest lubricants manufacturers in Russia, the plant is part of the structure. LUKOIL-a It specializes in the production of oils for automotive, aviation and Small motors, including outboard motorsIt is important to note that the PNPS does not just pour oil into canisters, but deals with the full production cycle: from cleaning the base oil to adding additive packages.

For boaters, two lines are of particular interest:

  • πŸ›₯️ M-8V and M-8DM - mineral oils for two-stroke engines (including outboard motors)
  • βš™οΈ M-10G2K and M-6S/12G1 Universal and semi-synthetic oils for four-stroke power units

The key difference between Perm oils and imported analogues is the use of group II base oils This allows for stable performance even when running on high-sulphur fuels (relevant to regions with low gasoline quality), but there is a major disadvantage: compared to synthetic oils based on the use of gas. PAO Permian products oxidize faster and require more frequent replacement.

⚠️ Attention: PNPS oils are labeled according to GOST 17479.1-2015, and not according to international API/ILSAC standards. This means that the inscription "M-8B" on the canister is not equivalent, for example, API-TC. Always check the table of compliance (see section below).

Classification of Perm oils: how to read the label

Labeling oils from PNPS can be confusing even for an experienced mechanic, and let's look at what the letters and numbers on the label mean.

  • πŸ”’ Number (M-6, M-8, M-10) - indicates the viscosity class according to GOST (roughly corresponds to SAE 20, 30, 40). M-8 (for 2T) and M-10 (for 4T).
  • πŸ…±οΈ The letter "B" or "D" - engine type:
    • In High-forced engines (e.g. outboard motors)
    • D. Diesel (not relevant for boats)
    • G. - Four-stroke petrol
  • πŸ”€ Additional symbols:
    • DM - with washing-dispersing additives (important for 2T engines)
    • 2k - for carburetor engines (suitable for most outboard motors)

An example of decryption: M-8V1DM - oil for high-forced two-stroke engines (viscosity ~SAE 30) with detergent additives. M-10G2K - universal oil for four-stroke carburetor engines (viscosity ~SAE 40).

πŸ“Š What kind of oil do you use in your outboard motor?
Permian (PNPS)
Imported (Mercury, Yamalube, etc.)
Other domestic
I don't know what it is.

For convenience, we have compiled a table of compliance of Perm oils with international standards:

Marka PNPR API analogue Analogue by JASO Recommended application
M-8V1 API-TB JASO-FB Old 2T engines (Whirlwind, Moscow)
M-8V1DM API-TC JASO-FC Modern 2T outboard motors (up to 50 hp)
M-10G2K API-SG β€” 4T outboard motors (Honda BF, Tohatsu MFS)
M-6S/12G1 API-SJ/CF β€” Universal for 4T engines (including turbocharged)
⚠️ Attention: Oil M-8V1 (without additives "DM") is not suitable for modern two-stroke engines with a direct injection system (for example, Evinrude E-TEC or Mercury OptiMax) Its use will lead to the formation of soot on candles and pistons.

Perm oil for 2T outboard motors: pros and cons

Two-stroke outboard motors impose strict requirements on oil: it must mix well with gasoline, burn without residue and protect parts from wear at high revs. M-8V1DM and M-8V2 They're positioned as a universal solution to these problems, and let's look at their strengths and weaknesses.

Advantages:

  • πŸ’° Price: 2-3 times cheaper than imported analogues (from 300 rubles / l against 800-1200 rubles / l for Mercury Premium 2T).
  • 🌑️ Temperature stability: It retains viscosity at -20Β°C (relevant for early spring/late autumn).
  • πŸ›’οΈ Fuel compatibility: Reacts less to impurities in gasoline (such as methanol) than imported oils.

Disadvantages:

  • πŸ”₯ Ash: It forms more carbon than synthetic oils (critical for catalyst motors).
  • πŸ•’ Duration of service: Requires a replacement every 50 hours (vs. 100 y) Yamalube 2M).
  • 🌊 Environmental friendliness: Does not comply with the JASO-FD (high smoke during combustion) standard.

πŸ’‘

To reduce the nagaroformation when using Perm oil in a 2T engine, reduce the proportion of oil in the fuel mixture from 1:50 to 1:40. This will increase oil consumption, but prolong the life of candles and the piston group.

The issue of mixing Perm oil with imported oil deserves special attention. According to tests conducted by the magazine Boats and Yachts in 2022, mixing is a problem. M-8V1DM s Mercury Premium 2T In a 50/50 ratio, this results in:

  • ⬆️ Increase in ash content by 15%
  • ⬇️ Decrease in flash temperature by 8C
  • ⚠️ Risk of emulsion formation when storing the mixture for more than 2 weeks

Perm oil for 4T outboard motors: is it worth the risk?

Four-stroke outboard motors (e.g., Honda BF50 or Suzuki DF9.9) require oils with high detergent and antioxidant properties. M-10G2K and M-6S/12G1 They are technically suitable for viscosity (SAE 30/40), but have a number of limitations:

Critical moments:

  • πŸ”§ The following are not certified by NMMA FC-W: This standard is mandatory for oils used in marine conditions, and Permian oils do not pass it.
  • πŸ’§ Low resistance to water ingress: When working in salt water or with frequent immersion of the motor in water, the oil emulsifies faster.
  • βš™οΈ Incompatibility with turbocharged engines: PNOS oils do not contain additives to protect turbines (relevant to the Yamaha F150 et al.

However, for older four-stroke engines of domestic production (for example, Zid-4.5 or UA-15Perm oils remain the best choice, and their advantages in this case:

  • πŸ› οΈ Easy availability in the regions (sold even in rural shops).
  • πŸ”„ Less sensitivity to "old" fuel (octane number 80-92).
  • πŸ’Έ Low repair price in case of breakdown (parts are cheaper than for imported engines).

Check the date of production (storage period – 3 years)

Make sure the canister is not bloated (a sign of oxidation)

Shake the canister - there should be no sediment.

Use only original packaging (fakes are common)

-->

If you still decide to pour Perm oil into an imported 4T engine, reduce the replacement interval from 100 to 50 hours of motorsport and install an additional fine cleaning oil filter (e.g., Mann W914/2).

Comparison of Perm oil with imported analogues: tests and reviews

To objectively assess Perm oils, we analyzed the results of independent tests (laboratory "AvtoVAZtest", 2023) and reviews of water engines from forums. FishHaus.ru and BoatPlace.ruThree things were compared: wear protection, engine cleanliness and oxidation resistance.

Parameter M-8V1DM (PNPS) Mercury Premium 2T Yamalube 2M Liqui Moly 2T
Wear of piston rings (ΞΌm/100 h) 12.4 8.7 9.1 7.8
Pistons deposits (g) 0.85 0.32 0.41 0.28
Flashpoint (Β°C) 210 230 225 235
Price per 1 l (ruble) 350 1100 950 1200

The reviews of water motors are divided into two camps:

  • πŸ‘ Supporters: β€œFor 5 seasons on Tohatsu 9.8 M-8B1DM: No breaks. I change the oil every 30 hours and I don't worry.Alexey, Kaluga).
  • πŸ‘Ž Opponents: "After the season, I had to clean the carburetor and change the candles in Perm oil. I won't take any more risks."Igor, St. Petersburg).

Results of long-term test (200 hours)

Two identical motors participated in the test. Mercury 15 (2018) The first one worked for M-8V1DMsecond, on Mercury Premium 2TAs a result:

Compression in the Perm oil cylinder fell by 12% (versus 5% for Mercury).

On the piston and candles of the first engine, deposits up to 0.3 mm thick were found.

Fuel consumption in Perm oil increased by 7% due to the deterioration of heat transfer.

Conclusion: Perm oils are justified for budget engines with a simple design (for example, Whirlwind-30 or Nevsky 5For modern high-speed engines (Evinrude, Suzuki) it is better to choose imported analogues.

How to distinguish the original Permian oil from fake

Fake oils are more common than those of imported brands, due to low price and high demand. According to Rosstandart, up to 30% of Perm oil canisters on the market are counterfeit.

Indications of the original:

  • 🏷️ Label: Holographic sticker with LUKOIL logo and QR code (leads to the website) lukoil.ru/verify).
  • πŸ“¦ Canister: Tight plastic with embossed "PNOS" at the bottom.
  • πŸ’§ Color and smell: A light yellow hue (not cloudy!) with a slight smell of sulfur (not sharp!).
  • πŸ“… Date: Laser printed (not labeled) in format DD. MM. GG..

Typical forgeries:

  • 🚨 Canisters with typos ("Perm motor oil" instead of "Perm motor oil PNOS").
  • 🚨 Labels without hologram or with a blurred QR code.
  • 🚨 Oil with a reddish tint (a sign of adding cheap additives).

πŸ’‘

Buy Perm oil only from official dealers of LUKOIL or in trusted stores (for example, 4 Rybolov, Corvette). Avoid spontaneous markets and online sites such as Avito without feedback.

If you doubt the originality, do a quick test:

  1. Put a drop of oil on the paper and wait 10 minutes. The original will absorb evenly, the fake will leave a greasy stain with clear edges.
  2. Place the canister in the freezer for 1 hour. The original oil will remain fluid, the fake will thicken.

Recommendations for use: proportions, mixing, storage

Even the original Permian oil will lose its properties if used incorrectly.

For 2T engines:

  • πŸ›’οΈ Proportion of mixture:
    • Old engines (up to 2000 BC): 1:25 (4% oil).
    • Modern engines (after 2010): 1:50 (2% oil).
  • πŸ”„ Mixing: Pour the gas first, then the oil. Shake the can before mixing carefully.
  • ⏳ Storage period of the mixture: No more than 30 days (additives settle).

For 4T engines:

  • πŸ“ Oil level: Check with a probe on a flat surface, the optimal level is between the "MIN" and "MAX" marks.
  • πŸ”§ Replacement: For Perm oils, the interval is 50 motor hours (or once a season).
  • 🌑️ Temperature: At -10Β°C, use oil M-6S/12G1 (similar to SAE 10W-30).

Pour out old oil (even if the engine is out of season)

Rinse the system with fresh oil (Pour, let work for 5 minutes, drain)

Pour the new oil before the mark "MAX".

Add a stabilizer additive (for example, Liqui Moly MoS2)

-->

Pay special attention to the storage of oil:

  • 🌞 Store the canisters in a dark place (UV rays destroy additives).
  • 🌑️ Optimal temperature: +5 C to +25 C.
  • 🚫 Do not use oil older than 3 years (even if the canister has not opened).

⚠️ Attention: Never mix Permian oil with esters-based oils (e.g., Motul 300VThis will cause precipitation and clogging of the oil channels. When you switch from one type of oil to another, flush the system with a special wash (for example, Liqui Moly Pro-Line).

FAQ: Frequent questions about Permian motor oil

Can Permian M-8B oil be used in the Mercury 25 hp engine (2020)?

Technically possible, but not recommended. Mercury 25 class oil API-TC-W3 or NMMA TC-W3who M-8V1DM Risks: increased soak on the pistons and reduced candle life, if there is no alternative, reduce the interval of oil change to 25 hours and use a ratio of 1:40.

What's different about the M-8B?1 M-8B1DM?

M-8V1 base oil without detergent additives, suitable for old engines with a separate lubrication system (for example, Moskvich-10). M-8V1DM It contains dispersant additives that prevent the formation of lacquer deposits. For all modern 2T engines (after 1990), you need to choose this one. DM- version.

What is the resource of Perm oil in a 4T outboard motor?

At moderate loads (up to 4000 rpm) and temperatures up to +30 Β° C oil resource M-10G2K form 50 hours of motorsportWhen you're in heavy use (trolling, high speeds) or in salt water, you reduce the replacement interval to 30 to 40 hours. Yamalube 4M It is 100+ hours in the same conditions.

Can Permian oil be poured into the Tohatsu MFS 9.8 (4T) engine?

Yes, but with reservations. Tohatsu MFS 9.8 class oil API-SJ or higher than that which is appropriate to M-6S/12G1But:

  • Use only original oil (the risk of counterfeiting is high).
  • Replace the oil every 40 hours (instead of 100 on the manual).
  • Add an anti-corrosion additive (for example, Wynn's Anti-Corrosion), because Perm oils are weakly protected from salt water.
