How to Improve BS4 Splendor Plus Mileage – 12 Practical Tips
Hello friends, welcome to Rajesh Technical Blog. Today I am going to share 12 easy and proven tips to increase the mileage of your BS4 Hero Splendor Plus bike. Many people complain that mileage is going down day by day, but the real reason is not the bike – it’s the way we ride and maintain it. Follow these points carefully and you will see a big improvement within a week.
1. Regular Service on Time
Service is the first step toward good mileage. Always do bike servicing on time — clean carburetor, check spark plug, clutch wire, and brake shoes. A well-maintained engine burns fuel properly and gives smooth performance. Service after every 2500–3000 km.
2. Use the Recommended Engine Oil
Hero Splendor Plus BS4 needs proper grade engine oil. Change it on time and never delay. Old or dirty oil increases engine friction and reduces mileage. Fresh oil helps the piston and clutch work smoothly.
3. Clean Air Filter Regularly
When the air filter is blocked, the engine gets less air and more fuel, which drops the average. Clean or replace your air filter every 3000 km. This one small habit alone can add 3–4 km/l to your mileage.
4. Maintain Tyre Pressure
Low air pressure increases rolling resistance and makes the engine work harder. Check tyre pressure once a week and keep it as per company standard — usually 25 PSI (front) and 28 PSI (rear) for single riding.
5. Ride Smoothly and Calmly
Hard acceleration and sudden braking waste a lot of fuel. Always start slowly, keep a steady speed, and avoid unnecessary gear changes. Smooth riding is not only safe but also increases fuel economy.
6. Shift Gears at Right RPM
Don’t drag the engine in high gear or over-rev in low gear. Shift gears at the correct RPM range. For Splendor, it’s best to shift between 25–45 km/h speed gradually. Correct gear shifting keeps engine load balanced and fuel burning complete.
7. Use the i3S (Start-Stop) Feature
If your Splendor Plus model has the i3S system, use it properly in long traffic lights. It automatically turns off the engine when idle and starts again with one clutch press — saving fuel every single stop.
8. Keep Chain Clean and Lubricated
A dry or tight chain takes more engine power. Clean and lubricate your bike chain every 500–700 km. This helps smooth transmission and improves pickup as well as fuel average.
9. Avoid Overloading
Carrying heavy bags or riding with two people continuously reduces average. Keep your bike light and balanced. Extra weight puts pressure on the engine and increases fuel use.
10. Use Quality Fuel Only
Always fill petrol from trusted fuel stations. Poor quality fuel or adulterated petrol damages the carburetor and reduces mileage. Don’t mix extra additives — the Splendor engine is already tuned for efficiency.
11. Check Brakes and Wheel Alignment
Sometimes tight brakes or wrong wheel alignment reduce mileage without notice. Check if the wheels move freely when bike is on stand. If not, get it adjusted during servicing.
12. Plan Your Route Smartly
Short cuts full of traffic can waste more fuel than a longer smooth road. Avoid unnecessary idling in jams. Ride at steady speed between 40–50 km/h for the best fuel economy.
Bonus Tips
- Check engine oil level every 1000 km.
- Don’t start engine with full throttle.
- Warm up the engine for 30 seconds in winter before riding.
- Clean the spark plug tip every 2000 km.
- Use genuine Hero parts during servicing.
Expected Mileage Result
A properly maintained BS4 Hero Splendor Plus can easily deliver 65–75 km/l in city riding and even up to 80 km/l on highways if you follow these simple habits. Many riders have achieved this range just by servicing on time and riding calmly.
Final Words
Your Splendor Plus is already one of the most fuel-efficient motorcycles in India. You only need to take care of it like a good friend. Regular check-ups, clean filters, proper tyre pressure and disciplined riding style — these are the real secrets behind excellent mileage and long engine life./2025/11/tata-motors-125cc-bike-launch-price.
Remember: Fuel efficiency is not about luck, it’s about discipline. The more care you give your bike, the more kilometers it will give back to you.
