    High volume oil pump

    Hey everyone,
    I was looking at oil pumps on rock auto. There are standard and high volume oil pumps. Any opinions on whether upgrading to a high volume pump is beneficial? More is better? Or just use what the car has which I guess would be a regular one. No factory oil cooler, don't plan on adding one. Conservative driver here. Thanks

    I’ve had several 87-90 2.8/3.1 engines and never had oil pump problems. Some over 300k like my 89 Celebrity. So I would think the factory one would be just fine.

      With a stock capacity pan, I do not recommend a high volume oil pump. The reason is, if the engine gets over a quart low and you are buzzing on down the interstate at a high rate of speed, it is possible for the oil pump to evacuate the crankcase of oil and starve the engine of oil.

        Thanks! If it ain't broke don't fix it, uh? The regular pumps are cheaper anyway.
