Just bought a new 2007 Civic LX 2 weeks ago. Considering using Pennzoil Platnium Synthetic oil, Purolator filter, and installing a drain valve from fumotovalvesoon. When should I make the switch? I am concernedwith the engine "break-in" period.

 

Clarify: Still have the same factory oil installed. I believe it is 5w20 dino. The switch refers to dino --> synthetic.

 

i would wait till the first oil change to do anything...cant explain why, but i've heard somethign to that effect before.

 

I'd agree, leave the factory oil in there until you need to do an oil change. It typically has some special addatives to help facilitate proper break in and wear, then switch.

 

Thanks for the info.
