    Specs look good, but 14$ for a oil filter ouch. Bob the oil guy did tests and believe it or not purolator filters are really good.

    LOL - read the stickies - been saying that for a very long time
    Wix filters are almost as good and have better flow rates.

    Purolator Pureone filters are quite good - std Purolator, not so.

    Sorry - don't know much about the Hastings.

    Did you change the weight of the oil? Pressure is a resistance to flow, which isn't always the best thing. So if you did not change the weight of your oil that increase is probably due to the oil being older and losing viscosity. Now if you just changed the filter with another and got a increase in pressure, that filter is not flowing as well.

    The pressure sensor is after the filter - it senses pressure in the oil channel that feeds the bearings & squirters. If anything, the synthetic media in the Platinum will flow better than cellulose in the Gold. That would explain the small increase in pressure at the sender.

    Pressure goes up as flow goes down and filtration goes up. Just as a supercharger on a stock engine might see 10psi. Take that same engine, port the head with valve job, change nothing at all besides that. Reinstall the supercharger and the same setup will see probably 6psi with more power than the prevoius setup. Why because the head is flowing more which means the pressure aka resistance to flow will go down. Trust me I know I was in that exact position. Its fluids dynamics 101, I'm not saying the filter is no good, actually saying the filter is actually filtering better. Just not flowing as well.
