hey i have a 2004 Mazda rx8 with 62,xxx miles it seems to run fine but i was wondering what are some things i can do under the hood to keep it in tip top shape like just little up keeps that arnt to expensive but will keep the car performing to perfection all submits are well appreciated ......Thanks guys.

 

Upgraded sparkplugs/coils, heatwrapped A/C line, some other stuff that I can't really think of

Sparkplugs and coils are the big ones though. If you haven't replaced them already you should definitely get around to it. You could also upgrade your starter, but that's a pretty expensive ($400+) "little thing", so I dunno if that'd be an option for you.

 

Change the oil frequently (between 3 and 5K miles).
Stay up to date on the condition of your ignition system. Plugs need to be changed every 30K miles or so. The coils can wear out pretty quickly too. Some swear RX8 coils die by 30K miles, but mine have lasted just over 50K and are just starting to go bad. Just stay on top of them. Either replace them with new RX8 coils or buy the BHR ignition coils and wires.
Be sure the engine isn't just putting around at 3K RPM every day. Rev it up. You won't hurt it and these engines build up carbon deposits pretty quickly if you don't.

Everything else is basic maintenance. You can research different oil weights and premixes if you want, but nothing in that area is solid and everyone will tell you something different. I've always run 5W20 and my original engine still pulls strong at almost 51K miles. But that's just me.

 

little things? red line everyday.
