    Hey guy's I am new here. I just bought a 87 K5 Blazer. I have noticed when sitting still the oil pressure needle seems to drop or move between 30 and 50. When I am driving the needle hangs right around 50. Is this normal?

    Oh and here is a picture of my truck...

    I have a stock '87 also and when I'm driving my gage will peg out at 60. From what I hear that seems to be about par.

    BTW; what size tire you running. Nice looking K5. Is it black or dark navy blue? How does the inside look? I almost went with a single dark blue instead of keeping the two tone. Mine has the light blue interior so I didn't have any choice but to keep it blue on the outside.

    Your oil pressure is fine. What kind of filter are you running? Frams are famous for fluctuating oil pressure.

    I think it is a fram. Just got the truck about a week ago...

    What type of oil filter do you recommend?

    Really? I run a fram with the grippy stuff on the bottom. I used to run a K&N oil filter and I got a few pounds less in oil pressure. Either that or now its just colder weather... :doah:

    As far as oil filters I like Wix (napa gold, Carquest are wix) Purolater filters,
    For cheap filters I like Champion labs filters. (WM tech 2000)
    I would rather use a roll of toilet paper than a base Extra Guard fram filter. . The higher priced frams are ok.
    I have had problems with Fram filters: 1. Oil pressure started acting funny. Pulled off fram filter and found it had came completly apart inside. The filter medimun (What little there is of it) came loose and was floating around inside the can.. 2. The anti backflow valves do not work well allowing the oil in my oil cooler and the rest of the lube system to drain back into the pan giving me dry starts.
    IMHO they are very low quality. The only reason they are so popular is they pay Big stores and autoparts chains to only carry their products. Then do heavy marketing.
    Do a search google or whatever. There is all kinds of info on frams out there. Many people on other car forums have bad opinions about them
    Search the words, Oil filter study. Interesting stuff.

    Wow!!! That's a sweet ride, brother!!!! :bow: :bow:

    Your oil pressure sounds fine, my friend. I would also advise against the Fram filters. I used them for years in my 84 K5, and the engine knocked during every cold start for years until I switched to Purolator filters.

    If you'd like some more info on oil filters, check out the floowing links:

    and

    Hopefully you find these informative, my friend!!!! :thumb:
