I use Honda Civic 2004 manual. Since the time I bought the car, it has been realiable. Its actually stated in the review of the car the engine noise especially at the high speed. I notice that when atmospheric temperature is high I.e during 'sunning' afternoon, I usually observe that the engine noise is high but engine is moderate during a colder atmosphere I.e in the morning, when its raining or just rained.
Pls any suggestions

Note that the engine is ok. It starts once and doesnt give any problems. I have not observed any significant difference in fuel usage during both period.

Havr the noise recorded and upload it here. What type of noise if I may ask?
