For quite some time I have been experimenting with different filters on my 4.0 tacoma. As many of your are aware this engine can be very noisy with the wrong filter. Up until yesterday I was running a non recommended filter from Amsoil (Eao34) which is larger than factory. Don't do it. Rattled like a mother. The Mobil 1 made it better. After adding the RP all of the noise went away completely!
I also noticed that with the Eao34 it was always empty when removed. Leaky DB valve no doubt. I like the Eao57, but not the 034. My truck seemed to shift strange, made terrible noise( no it was not in my head). These RP filters are impressive. Now maybe it's time for a few particle counts!
IF I can find an extra $75
