Amsoil oil filter and low oil pressure

Jhill

What’s the ea15k 50? I’ve been using the ea15k 12 with no issues. I’ve heard amsoil have a similar issue with one of the Toyota v6 engines in the past (I don’t remember which now) but that was with one of the 25k filters and they even took it off their site as the filter to use for such vehicle. Just checked tonight and see the ea15k 12 is still the recommended one for the 370z. I’ve been using it since I got the car and done track and street driving and oil test always came back good. I’ll continue to use this one since I just did a change and then I’ll see what a sip says on next change.

Oh and I do 10k with signature series. Not comfortable with 15k and signature series is a bit pricey to be changing as often as OEM.

This was for 5.7 and 6.4 Hemi's. But it can happen to any filter with long oil changes. Just something to keep an eye on.

Well as they say it also depends on the engine. In this case the hemi and in the case of the Toyota I referenced they are “dirty” engines so they plug the filter. Not had any issues on this car and never had any in my VW before which is actually surprising to me cause the VW oil always looked like crap and I’d think a Toyota would be cleaner but I guess looks aren’t everything. Cars old by now (2009) and as I said in the case of the Toyota they removed it as a filter to use from the application guide and I’d assume they’ve done the same for the hemi and I’ll assume they’d do so for ours if it has issues. They’re pretty good about their testing.
