This is just as full of arguments as the regular gas vs premium gas debate.
I use a secret system developed by Nasa in conjunction with Stephen Hawking and Homeland Security to calculate when to change my oil.
The calculations take a few hours on a supercomputer, but it is all worth it.
(I can sneak the time free, so that is covered)
After i drain the oil, it is sent by special courier service to a secret lab in area 51 where it is bombarded with a high intesity cosmic ray source from the alien spaceship. Then sent to a 3 mile deep shaft where it is studied for signs of alien intelligence.
After that it is fed to gerbils.
So far only two of the gerbils have started speaking in Aramaic.. but it looks very promising.
I can say no more.
