I've read lots of good stuff about MMO in our cars(I use it in my GFs MX6, but never tried it in my 7) so I plan to try it in both the gas and oil. Now, would it be safe to use right from the get-go with my rebuild coming up? Or should I just wait for the break-in procedure to get done?(Oh and break-in is -4000RPMs for 500 miles, change oil; -6000RPMs for 500 miles, change oil-and no BOOST?) Thanks alot.

 

If you rebuild your own engine then it is suggested for use as a lubricant when putting the motor back together so I would say use it from the beginning. -Gabe

 

Im sure it wouldn't hurt, I think it all comes down to matter of opinion.

 

I put it in my gas tank for a little extra lubricating insurance.
