oops , please excuse me, I wandered onto another Hybrid thread...I forgot to keep it SiMpLe here on this thread.
BTW, I found that using regular fuel with 87.02009 octane runs better than 86.5.9978 octane and I am achieving 27.007337 MPG as compared to 26 .6937006 MPG.
I'm going to try "Luk" oil Regular and see if the 87.555590 octane gives better MPG results.
I'll keep yu guys posted.
