I agree with the Pure One. I have a new Civic EX coupe. Planning on changing to synthetic, though going with 5W-20 like the manual recommends. Doing it for mileage and I run synthetic in our 06 Vette.
Wondering what everyone thinks about how soon you can change to synthetic? Is it ok to do it right away? She has about 1300 miles on her, I usually like to make the first oil change early.
Also looking for a good air filter, any recommendations? All this done to get even better mileage, not really looking to soup the thing up.
