Tips for Choosing the Budget Engine Oil for Old Petrol Cars in India
- Stick to manufacturer-recommended viscosity: For older petrol engines, 15W-40 or 20W-40 are often ideal.
- Prefer mineral or semi-synthetic oils: Fully synthetic oils are excellent but may be unnecessary and costly for high-mileage, low-power engines.

- Consider usage and climate: If you drive in hot and dusty conditions, prioritize oils with better thermal stability and detergency.
