Hi all! I was looking on amazon,just thinking. Might wanna try Castro 10w30 this summer.never tried it,so got that itch.or valve line dino 10w30.
Looking at Castro oil filters,very curious...mine would be CAS3387. 20,000 mile protection. But no efficiency.
I found an older post, 2016..sfx or something like that Castro filters..99.9%@25 microns.
What are the newer cAs Castro synthetic filters rated?band at 5-10 microbs?
