Next oil change for me...

 

Hi,

I don't have their motor oil, but I use the NEO RHD in my TC and rear diff. I also used it in my wife's old WRX, which specifies a GL5 fluid throughout.

It's spendy, but their stuff works excellent. I'm at 33K miles, and with Redline MT-90 in the transaxle, car shifts great. The dreaded decel noise is also gone.

Anyway, I think highly of NEO, although it's spendy not not readily avail near me, I've had to order it. I'm interested to hear about the motor oil experience though.

Take care,
