Planning to explore Bali’s beaches, temples, and jungles on a rented Honda Vario? Smart choice!

But with so many fuel options at the gas stations, you might find yourself asking, what gasoline should I use in Vario?

Choosing the wrong fuel can ruin your trip with engine troubles. Here’s your stress-free guide to Vario fuels, tailored for Bali’s terrain and Pertamina’s gas stations.

Why Your Vario’s Fuel Matters in Bali

Bali’s hills demand peak engine performance. Use low-octane fuel in Canggu's steep roads? You risk knocking (metallic pings from poor combustion), overheating, or even engine damage. 

The right fuel prevents this while boosting mileage—critical for long rides from Seminyak to Ubud.

Bali’s humidity accelerates ethanol phase separation in fuel. If your rental sits unused for days, phase-separated ethanol attracts water, causing fuel system corrosion. More on fixes later!

Engine Tech & Compression Ratios in Vario

Not all Varios are equal! Their compression ratios (squeeze power before ignition) dictate fuel needs:

Model

Compression Ratio

Engine System

Vario 110

9.2:1 - 10.7:1

Carburetor or PGM-FI

Vario 125

11.0:1

PGM-FI (Fuel Injection)

Vario 160

12.0:1

PGM-FI (Fuel Injection)

This technical term essentially tells you how much your engine compresses the air-fuel mixture before ignition. 

A higher compression ratio generally requires a higher octane fuel to prevent engine knocking (a harmful phenomenon where fuel ignites prematurely).

Knowing your specific Vario model is the first step in making the right fuel choice.

Fuel Recommendations Based on Vario’s Model

In Indonesia, you'll primarily encounter Pertamina fuel stations, offering various gasoline grades identified by their RON (Research Octane Number) values. 

Here's a guide to what gasoline should I use in Vario based on Pertamina's offerings and your Vario's compression ratio:

1. For Vario 110 (Compression Ratio: 9.2:1 - 10.7:1)

Pertalite (RON 90) is generally the ideal choice for the basic Vario 110. 

For the Vario 110 FI (Fuel Injection) models, Pertamax (RON 92) is recommended.

This range of RON 90-92 perfectly matches the compression ratio, preventing knocking and the build-up of harmful deposits. 

Using a fuel that meets or slightly exceeds the recommended RON ensures stable combustion.

2. For Vario 125 (Compression Ratio: 11.0:1)

Pertamax (RON 92) is the minimum requirement for the Vario 125.

For optimal performance and engine longevity, Pertamax Green 95 is highly recommended.

A compression ratio of 11.0:1 necessitates higher octane fuel to maintain stable combustion and controlled engine pressure. 

Using anything less than RON 92 can lead to inefficient burning and potential damage over time.

3. For Vario 160 (Compression Ratio: 12.0:1)

Like the Vario 125, Pertamax (RON 92) is the absolute minimum you should consider.

Pertamax Green 95 or even Pertamax Turbo (RON 98) would be the optimal choice for the Vario 160.

The high 12.0:1 compression ratio of the Vario 160 truly benefits from higher octane fuel. 

This ensures maximum power output, prevents knocking, and contributes to the overall health of its sophisticated engine.

Remember, the goal isn't just to use the highest octane fuel available, but to use the correct octane. 

Going far beyond your scooter's requirement, while not harmful, offers no additional benefit and simply adds to your fuel costs. 

This is where understanding octane myths becomes helpful; more isn't always better.

The Impact of Using Incompatible Fuel

Using the wrong fuel, especially one with a lower RON than recommended, can have several detrimental effects on your Vario, potentially turning your Bali adventure into a roadside headache:

  • Engine Knocking/Ping (Pre-Ignition): This is the most immediate and audible sign. It's the sound of fuel igniting too early in the combustion cycle, which can cause significant internal engine damage over time.

  • Reduced Performance and Power: Your Vario won't deliver its intended power, leading to sluggish acceleration and difficulty on Bali's inclines.

  • Decreased Fuel Efficiency: Paradoxically, using lower-octane fuel when a higher one is required can decrease your mileage because the engine isn't operating efficiently.

  • Increased Emissions and Carbon Buildup: Incomplete combustion from unsuitable fuel can lead to more harmful emissions and excessive carbon deposits within the engine, impacting its long-term health.

  • Damage to Fuel System Components: Modern scooters, especially those with fuel injection systems, are precisely tuned. Incorrect fuel can lead to issues like fuel system corrosion or clog injectors. While Honda Varios are generally robust and modern scooters are designed to handle up to E10 compatibility, prolonged use of inappropriate fuels or those with high ethanol content (if not designed for it) can lead to ethanol phase separation and other issues, especially during storage best practices or if fuel stabilizers aren't used for longer periods. 

For a worry-free experience, it's always best to err on the side of caution and use at least the minimum recommended RON.
