Oil Filter for HP500EFI
 

I am looking for the model number for Mobil 1 Oil filters for HP500EFI. model year is 2001. Also where can I buy these. Thanks.

cross over a ,,A/C pf35 to the mobile filter /I get them at auto zone ,ect

I checked at Autozone, the PF35 cross referenced to a 302 Mobil 1. Seem right?

Buy the Napa Racing (built by Wix) 1061R. It is better than the Mobil 1. Mobil 1 would be my second and only other choice.

The PF35L is the AC-Delco synthetic filter (or so ive been told) just make sure the L is on the end.. :)

yES THE L IS THE KILLER a/c filter but its hard to cross the mobiles all come with syn media anyway and the 302 does sound right ! I don't know about WIX media but they make the amsoil filters for them and I vote for the pf35l or the mobile one ,the 35 and the 35l are the same phyisical size so I use it to cross to mobile :D

Just look for a suburban with a chevy 454. I think it is a m302. They should have the book in Autozone.

I have 1994 454 mag blown 630hp would filter be the same for me.

YEP its a great choice in my eyes:D :D :D

I like the pf932c because of its extra oil capacity. Any time you can add capacity to the oil system is a good thing in my opinion.

Speaking of oil capacity,

The Cat filters on my sea ray's diesels each hold right at a GALLON of oil each. Each time I change them, I get amazed as I keep on and keep on and keep on pouring oil into them before spinning them into place...

Mobils part # is M1-302

Auto Zone and Murrays carry them by me

Anybody try K&N? I'm going to this season?

The mobile one should hold the pressure all you need is 8 to 10
lbs. per thousand RPM.. anymore you kill the dist. and cam gear and for sure if its brass gear on the dist.
It also wastes 10 to 12 hp or more to drive the pump !

Hope this helps :D :D

If you are using the AC Delco filters you should use #1218. These are the same size as the PF35 but they have a anti backflow valve to prevent the oil from draining out of the filter when the engine is off.

I use the K&N Filter. No problems, I use the K&N on all my vehicles

Racing filters
 

Alot of the racing filters are concerned with not cutting down flow and short term use . The A/C35L and the mobile have special elements in them that are expenseve but flow alot yet stop very small parts and the filter media (element) is made for syn. oils as well . I am sure a/c sold the rights to their L filter media to moble and this is what makes them work so well
K&N are made by either wix or someone else
Pressure should not be a problem with anything we run as most will hold 80 to 90 psi which is way to much oil pressure anyway ,you only need 8 to 10 lbs per 1000 rpms anymore than this and it loads the dist. gear to hard and takes power;)
