I use valvoline Vr-1 20-50, Its nice oil and Cheap!

 

I was running 10W30 until yesterday, I did an oil change on my car, and put in 20W50. It's running a lot smoother now, it may just be my imagination... but the car just feels 10x stronger.

 

Go to your local auto parts store and pick up a copy of Hayne's RX7 manual, and read as nuch as you can. Or if you got the factory owners manual if you got it. There both really good.

 

Punch the hole n the oil filter (good one Icemark)

Then find the plug and unscrew it,

Remove oil filter

Wait till all oil is drained, then reverse all,



Oh yeah make sure the drain plug on the drain pan is open.


Haha never a perfect change. oh well

 

If your OMP is still working and installed, synthetic is not the best choice. If your omp is blocked off go for it. at least that seems to be the the common agreement i have seen.
