Vehicle has about 118k miles. 4.6l v8 I’ve 2 drain and fills with AMSOIL atf fuel efficient due to its protection and full synthetics. The first one involved dropping the pan replacing the filter After getting a feel for how it drives it doesn’t feel like like the oem feel before I started the drain and fill and kinda rethinking if I should’ve went with the WS. Nothing else is wrong could be overthinking it. The question is would it be ok to do a few more drain and fills with the WS to get the AMSOIL mostly out or should I just ride out the AMSOIL atf till the next interval?
