⛽ Why Fuel Type Matters So Much

A machine, essentially, is something that turns fuel into motion. In a diesel, even the combustion is more a function of the quality and type of the fuel.

⚠️ Your low-quality or improper fuel for your Yanmar 8LV370 can result in:

Poor burn performance
Less power output
More wear and tear on engine components
More emissions
More likelihood of engine wear and injector failure

🧪 Diesel Engine Fuel Fundamentals

The Yanmar 8LV370 will run on high-quality ultra-low sulfur diesel (ULSD). Using the right type of diesel, there is sufficient atomization at injection, clean burn, and long-term dependability.

Some of the most important characteristics of good marine diesel are:

Cetane number: at least 45 (has an effect on the ignition delay)
Sulfur content: Below 15 ppm (ULSD standard)
Cleanliness: Free of microbes and debris, water-free
Lubricity: Free flow of injector and pump

🚫 What If You Put in the Wrong Fuel?

You’d be amazed at how many boaters compromise engine condition by filling up at the wrong dock or fueling in out-spec diesel into the tank. The Yanmar 8LV370, as with any high-performance engine, is finicky about tank contents.

❌ Top-Up with the Wrong Fuel Issues with Your Engine:

Problem	Cause	Result
Dirty injectors	Dirty fuel	Loss of power, poor spray pattern
Over-smoking	High sulfur content	Breaches of emissions regulations, soot buildup
Fuel pump failure	Low lubricity fuel	Inefficient, costly to replace
Water contamination	Disregard of storage or supply	Rust, rusty injectors
Microbial growth (diesel bugs)	Long-term storage in humidity	Clogged filters, engine stall

In short: cheap or incorrect fuel = costly problems.

🚫 Avoid These Most Common Errors

Here are a few fuel blunders Yanmar 8LV370 boat owners tend to make — and how to correct them:

❌ Error #1: Automotive Diesel

While it sounds almost the same, auto diesel is not marine spec and won’t keep as well in boat tanks. It often doesn’t have additives to be safely burned in boats.

✅ Solution: Keep only marine-grade ULSD.

❌ Error #2: Longer Than Necessary Fuel Storage

Diesel fuel deteriorates at 30–90 days, especially in warm or humid conditions. Contamination by microorganisms and phase separation of low-maintenance tanks.

✅ Solution: Stabilize with stabilizers, turn over fuel inventory, and clean tanks regularly annually.

❌ Error #3: Failure to Fuel Filter

Diesel can contain micro-particles or water even when it looks clean. Fuel filtering is called for.

✅ Solution: Utilize good quality primary and secondary fuel filters, and replace them regularly.

🛠️ Yanmar 8LV370 Fuel System Design

Yanmar 8LV370 has a common rail fuel injection, with fuel metered out with more than one injection per cycle. This provides more efficient combustion and lower emissions.

Such accuracy means that the quality of the fuel has to be even better. Injectors are exquisite bits of kit — any particle or single drop of water will affect performance.

⚙️ Impacted by Fuel:

High-pressure fuel pump
Fuel injectors
Electronic control unit (ECU)
Fuel filters and separators

Keeping these units in top condition starts with good fuel.

📘 Yanmar’s Own Fuel Guidelines

Yanmar also provides some of their own fuel guidelines in their manuals, specifically for the 8LV series. Those guidelines are:

Utilize ULSD to EN 590 (Europe) or ASTM D975 Grade No. 2-D S15 (USA)
Minimum cetane index 45
Sulfur content < 15 ppm
Keep in clean sealed storage tanks
Don’t use greater than bio-diesel blends B7 (7% bio-diesel)

Always refer to your Yanmar 8LV370 Owner’s Manual for current specs.

⚗️ Fuel Additives – Friend or Foe?

Fuel additives maintain fuel health but are not created equal. Use only factory-authorized additives on Yanmar 8LV370 engines, such as:

Anti-gel additives (in cold weather)
Biocides (destroy microbial growth)
Stabilizers (in storing for extended periods)

🚫 Do not use: Octane boosters, alcohol products, or “universal” cleaners that are not diesel-engine friendly.
