Why Franean 20w40 best choice for TVS Star City Plus motorcycle

February 28, 2026

Franean 20W40 Sports Plus Engine Oil, Franean 20W50 Cruise Engine Oil, or similar quality engine lubricants from Franean are a good choice for a commuter motorcycle such as the TVS Star City Plus — but with an important caution on manufacturer recommendations.

Understanding Motorcycle Engine Lubrication – The Basics

Every internal-combustion engine — including the 109-110 cc single-cylinder one in the TVS Star City Plus — needs high-quality engine oil to:

1. Reduce friction between moving metal parts

2. Carry away heat from combustion and moving components

3. Protect against wear, corrosion, sludge, and deposits

4. Maintain a stable lubricating film across wide temperature ranges

5. Ensure smooth operation and efficient fuel burning

Without proper lubrication, your engine can overheat, consume more fuel, suffer accelerated wear, or in extreme cases fail completely.

Manufacturers specify an oil viscosity grade & performance standard (like SAE 10W-30, API, JASO MA2) precisely to match engine design, tolerances, and operating conditions.

Franean Oils – What They Are

Franean is an Indian lubricant brand that makes engine oils engineered for the unique stresses of Indian roads and climate conditions. Its product range — such as:

· Franean 20W40 Sports Plus Engine Oil ·

· Franean 10W30 PRO Engine Oil ·

· Franean 20W50 Cruise Engine Oil ·

— are multigrade motorcycle engine oils formulated with base oils + additive packages offering wear protection, thermal stability, detergency, and oxidation resistance.

Key general features highlighted by the manufacturer and users include:

· Stable Viscosity & Thermal Resistance: Maintain protective oil film even at high engine temperatures so the engine runs cooler and smoother.

· Reduced Engine Wear & Noise: Additives help guard against friction and metal-on-metal damage.

· Engine Cleanliness: Detergents and dispersants minimize sludge and deposits, helping internal parts run clean.

· Lower Maintenance Costs: Good quality oil helps decrease the frequency of bearing, ring, or valve wear issues.

· Designed for Indian Conditions: Formulated to withstand high ambient temperatures, dust, stop-start traffic, and long rides common in India.

Why This Matters for TVS Star City Plus

To decide why Franean oils might be “good” for your TVS Star City Plus, we need to break this down into technical factors and real-world performance.

1. Engine Protection & Longevity

Franean motor oils are formulated to protect engine internals like pistons, rings, and crank bearings by maintaining a strong lubricating film. Good protection means:

· Less engine wear over time

· Less friction → smoother running

· Lower oil oxidation → longer life of the lubricant

This benefit translates to engine longevity, which is especially valuable in commuter bikes that rack up high daily mileage.

However, note that the Star City Plus owner’s manual calls for SAE 10W-30 engine oil with specific performance specs (e.g., JASO MA or equivalent), so you should choose a grade that matches those specs.

2. Viscosity Matching & Operating Conditions

Viscosity (e.g., 10W30, 20W40, 20W50) determines how easily the oil flows at cold & hot temperatures:

· Lower “W” grade (like 10W-30) flows more easily at startup and is ideal for modern small commuter engines — compatible with low-friction requirements.

· Higher viscosity oils (20W-40 / 20W-50) offer thicker films at high temperatures and are often chosen for older engines or very hot conditions.

For a motorcycle like TVS Star City Plus, which is a small 110 cc commuter, the manufacturer recommends 10W-30 or similar, because that viscosity gives the best balance of protection, pumping efficiency, and fuel economy.

So if you pick a Franean oil, go with one with the right viscosity grade per manual (e.g., a 10W-30 motorcycle oil).

3. Franean Additives & Cleanliness

Franean oils include detergents and dispersants that help prevent sludge and carbon deposits — a critical advantage in engines with frequent traffic idling (like in city commuting). This can lead to:

· More consistent performance

· Less buildup in combustion chambers

· Better fuel efficiency

These features help maintain engine smoothness and reduce long-term maintenance needs.

4. Suited for Indian Roads & Climate

Indian conditions (high heat, heavy traffic, stop-start riding, varied terrain) put significant stress on engine components. Oils that are engineered to handle such conditions tend to:

· Resist viscosity breakdown

· Provide stable lubrication even under thermal stress

Franean emphasizes that its products are designed for these Indian conditions — which may be a real benefit if you ride year-round in cities like Guwahati, Dispur, or anywhere with high heat cycles.

Important Manufacturer & Warranty Consideration

Even though a lubricant may perform well, it should still match the manufacturer’s recommended specifications:

The TVS Star City Plus manual specifically mentions motorcycle oil with a particular viscosity grade and performance spec for optimum engine performance & warranty preservation.

Using an oil that doesn’t meet the specified grade may lead to:

· Poor lubrication

· Higher fuel consumption

· Reduced engine reliability

· Possible service-warranty issues (many dealerships enforce this)
(This is something many riders have discussed — forums warn that non-recommended lubricants sometimes affect dealer service treatment).

So, if you choose Franean, verify that the oil you select matches the TVS recommended specs (API/SJ+/JASO MA2 as per manual) before pouring it in.

Real-World Comparison – Value vs Brand Options

Compared with premium motorcycle oils (e.g., Motul, Shell, etc.), Franean typically offers:

✔ Comparable basic lubrication & protection
✔ Good performance for daily commuting
✔ Lower cost and good value
✔ Engine cleanliness & thermal stability

However, premium brands often incorporate stronger additive chemistry and synthetic base oils that deliver smoother high-RPM performance, better sheer stability, and longer drain intervals — which might benefit riders who push their bikes harder. That said, for a commuter bike like the Star City Plus, Franean offers good day-to-day protection at a more affordable price.
