Those of you with higher HP FE engines - what oil do you run?

[767Jockey]

There's been no issue with the engine, no debris or anything like that. I would just like to get as much synthetic out as I can before the refill with the VR1. I was thinking I'd disconnect the oil cooler lines at the engine, place one end in a large container, and blow some low pressure air into the other line end, hopefully forcing out as much of the synthetic oil sitting in the cooler and lines as I can. Has anyone done that, does that sound reasonable, and has anyone got any better ideas?

No. First, you don't need to do anything, just change the oil. If you feel you must do something, run a surgical tube through a line and use a vacuum pump to suck it out. But really, you don't need to do anything. Don't make life hard on yourself. Just change the oil.

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 !
