I recently bought a 2008.5 mazdaspeed 3 2 months ago and I'm gonna completely service it all new oils/ filters new PVC valve and new sprk plugs cleaning of the egr installing an oil catch can cleaning the maf and doin a seafoam treatment on the valves. Car runs nice no smoking exhaust and runs smooth.. Question is what kind of motor oil is best for the car?? I don't care about it being cheap I want the best. I hear penzoil platinum synthetic is pretty good and so is royal purple. What's do u guys use?? And what other maintance items should I do aside from what I described? Car has 58k miles |
