I used Mobil 1 "extended performance" 5w30 in my 2000 mustang
but my 05 Mustang takes 5W20 , and the "extended performance"
has been impossible to find .
so I just bought the regular 5w20.(running it since day one)
I change my oil about every 2500 miles
until one day I was bored so I decided to to cut open a old oil filter.
I was shocked!
here is what I found.

excuse the fram, its all they had at the walmart, (thats why I don't buy oil or filters there any more)

so a buddy turned me on to Amsoil.
I signed up as a "preferred customer"($10 for 6 months,) which nets you a 20-25% discount
anyway I was so pleased with my new Amsoil products, (6 qts for the stang and 4 for my ninja.)I decided to become a dealer.
now with my bike....
I was running Mobil 1 mxt4 which costs like $9.75 at autozone which was suppose to be the best oil out there, and if you seen me ride my bike, you know I need a good oil

now after switching to Amsoil
the trans doesn't get hung up like it used to.it has 40,000 miles on it and it never shifted better,
Just thought Id share my mobil1 story with you guys.
