if toyota oil filters are really that good, then why aren't all oil filters made like the toyota filters?

Question

i have always heard that toyota oil filters have a (check valve) so oil will get inside your engine quickly when you start your engine, thus preventing unnessary wear and tear on your engine. if this is true, then why aren't all oil filters made this way?

Answer 1

There are lots of good aftermarket oil filters some with oil drain back check valve. But your right Toyota's oil filter is the best thing for your Toyota car. I've seen the cut a way on the toyota parts counter with more filter paper to trap particals too.

Answer 2

I don't think that's really a necessary or tremendous improvement. The oil is pulled from the pan/sump, which should already have plenty of oil when the engine is started. The filter doesn't, after all, hold very much oil. The quality of a filter is how small the particles it removes are, and how well the oil can still travel through the filter's mesh. If you want better filtration, see if there's a magnetic filter for your model. If not, use Engine Sentry in your filter. Any decent filter will do if you add these to it. They are potent magnetic balls that operate under high temperatures. They are available at the link below.

Answer 3

Actually, most quality oil filters do have check valves to prevent drainback of oil and if you really want to prevent oil starvation at startup, have an oil accumulator installed on your car and the engine will last 10 times longer. Racers use it to prevent oil pump cavitation in extreme cornering or acceleration on their million dollar engines and it's the best way to prime the oil system before startup which is when most engine wear happens.
