I was checking my oil level today and I noticed something kind of odd. My oil was still really new looking I changed it last week (almost 150 miles ago now) so i figured that it would look brownish-black like used oil is supposed to look.

im not complaining, but is that normal for a rotary?

 

Dont be too surprised, 150 miles is nothing.. must also be the sign of a healthy engine.
Now drive it around redline the entire week and tell us of any difference

 

this is because rotaries (if in decent condition) have significantly less blowby than piston engines.

In fact, I believe that the original recommended oil changes were 10K, also because you have to add new oil due to the OMP.

i used to change mine at around 5 or 6K and it would still look almost new when It came out. on a 100k motor.

 

i do oil changes every 2k or so... because im paranoid.

 

2k for me, but I just love giving her fresh oil... its dirty after 2k anyway.

 

You might not even have to change oil if you block off the OMP, and run on premix. The oil in the motor acts and functions just like gear oil. And how often do you have to change gear oil????

I am just joking. I change my oil every 3k.

I redline it at least once every time I drive it, if not every time I accelerate to 55. I change it every 2k also, but I might stop that because I am going to switch to synthetic and it costs more...

 

I think you just opened up a new can of worms by saying that you're switching to synthetic oil. Lets see how many pages will be wasted on this argument again.
