2017 Toyota Tacoma 3.5 V6, 103,665 miles.
Out: dealer fill, work order said Castrol full synthetic 0w20 when I bought the truck 3 months ago.
in: Mobil 1 ESP 0W30. Also installed new metal filter housing, reused OE filter stand pipe and bypass valve.
I used a full bottle of Redline SL-1 in the fuel tank about 500 miles ago and that must have cleaned something out somewhere, because the oil was nasty, and there was dirt/carbon in the filter and filter housing as well.
I did notice the timing cover sweats a little bit from the area they are known to leak from, gonna keep an eye on that...
