When I picked my 482 up from Blair , it already had a bunch of dyno runs at WOT on it with VR1 in the sump . All I did was put about 500 to 600 miles on it and really not very gently .... just never ran it at a steady rpm for any period of time . Vary your rpm and load . I figured since it already had a bunch of WOT dyno runs , I wouldn`t have to baby it .
When I changed to
Amsoil synthetic , no flushing . Just changed the filter and
oil . If you really want to "drain " the
oil cooler, undo the inlet and outlet hoses and use about 20 psi air pressure . Any higher makes a mess ..... ask me how I know . IMO , it`s not needed if you changed the filter . Cooler capacity compared to the rest of the system isn`t that much and shouldn`t effect break in ..... but Blair is the man to listen to . I still bug him every now and then .
So , go out there and have fun !
