I have Civic EXi 2005. It was on CNG and i drove it for 60,000 kms.
Now it is on Petrol and now i want to improve its performance.
I have 3 things in my mind:
I should add some Hi-Octane, when i will get its tank filled.
I should use Iridium or some other high performance Spark Plugs.
I should use some high performance Motor Oil, instead of Honda Genuine Oil.
So what Experts have to say?
Plz help me in selection of some good oil, some good spark plugs and also some other tips to improve acceleration of my Car.
