Whats going on everyone. I just got my rx8 and it has 91,900 miles. I have tried to search but i didnt find an answer. Im wanted to know if i should change the trans and diff fliud. The car is running great but i juat wanna make im giving it the right maintenance. Thanks.

 

Yes!

And coils, plugs, motor oil.

Check brake pads and air filter.

 

K will do the plugs coils and wires were done at 89k an it has a k n intake. But will deff change trans fluid. Thanks

 

use redline for tranny and diff

 

Royal Purple makes fluid for it too... Is there a significant difference in quality between the two?

 

CW around here is that Redline is the way to go. The RX-8 tranny is quite sensitive to oil. I tried 2 other brands before using MT-90 ... big difference!

 

I think it's a good idea to replace all fluids after picking up a used car.

 

^ Yes, unless you know for a fact that one fluid or another was replaced recently, replace 'em all.
