Best Engine Oil HONDA Civic X Saloon (FC_) (09.2015 - ...)

It is important to choose the right compatible oil according to the specification and operating conditions of the car. You can get quality advice from Avtodoc, and buy oil from top manufacturers. and everything you need for your car. For summer, you can use 5W-40, it is thicker, for colder regions, you still need to use 5W-30

For maintaining optimal engine performance, preventing overheating, and ensuring protection of your Honda during increasingly hot UK summers, the best engine oil choice depends largely on your specific Honda model and its manufacturer recommendations.

Recommended Engine Oil for Hot Climates in Hondas
- Follow the Manufacturer’s Manual: Most Honda models, including recent ones, specify synthetic 0W-20 oil for petrol engines as the ideal choice for balancing fuel efficiency and engine protection, regardless of climate. This oil grade is engineered to flow well at low temperatures and provide adequate protection at higher temperatures.
- Consider 5W-40 or 10W-40 for Older or High-Performance Engines: If your Honda is an older model or a high-performance variant, a semi-synthetic 5W-40 or 10W-40 oil may be recommended. These oils have higher viscosity at operating temperatures, offering better protection against wear and heat in hotter conditions.
- Synthetic Oils Are Preferred: Synthetic oils maintain their viscosity and protective properties better at high temperatures compared to conventional oils, reducing the risk of overheating and engine wear.
- Oil Specifications: Look for oils meeting ACEA A3/B3/B4 standards for robust engine protection in hot climates. These oils have stronger additive packages to resist breakdown and maintain viscosity under stress.

Practical Tips for Hot Weather Engine Oil Use
- Stick to Recommended Viscosity: Even if summers get hotter, it’s generally advised to stick with the oil viscosity recommended in your owner’s manual to ensure the engine’s design parameters are met.
- Use High-Quality Synthetic Oil: Choose a high-quality synthetic oil brand known for stability in high temperatures (e.g., Mobil 1, Motul) that meets or exceeds Honda’s specifications.
- Regular Oil Changes: Hot weather can accelerate oil degradation, so consider more frequent oil changes during summer months to maintain optimal lubrication and cooling.
- Check Cooling System: Complement oil choice with proper maintenance of your cooling system (coolant, radiator, fans) to prevent overheating.

For your Honda in hot UK summers, the best approach is to use the synthetic 0W-20 oil recommended by Honda for most petrol engines, ensuring it meets the latest Honda Genuine Oil specifications. For older or high-performance engines, a semi-synthetic 5W-40 or 10W-40 oil may provide extra protection against heat. Always prioritize synthetic oils with robust additive packages (ACEA A3/B3/B4) and adhere to regular oil change intervals to maintain engine health and performance under scorching conditions.
