That damn Archoil 9100. **** is amazing.
So yesterday I changed the oil, rotella T6. According to the previous owner, that's what was in the truck anyway. If he was honest about it, like he seemed to be about everything else so far. The oil I changed had about 8500 miles on it.
Motorcraft filters all around.
Changed the fuel filters too, they looked good. Not really dirty at all and were motorcraft. Id say they were def changed in the past year.
Anyway. Got in it just now. Cranked right up as usual, idled a tad smoother than usual, I then took it around the block on a cold motor.
Both ECT and EOT were like 70 something degrees by the time I got back. No white smoke. No hesitation. Instant throttle response. Pretty much feels like a fully warmed up truck, but it's cold. Very, very happy.
So my question now is. Do I add Archoil 9100 maybe every other oil change? Or only when symptoms present themselves again?
