Hey everyone,

I just accidentally picked up a bunch of Mobile 1 M1-303 Oil Filters from amazon, and realized that I should have gotten the M1-301s.

They look like they have almost identical stats side by side (except for the slight difference in Thread Size = 3/4"-16 vs 13/16"-16). Anyone know if these will these work interchangeably, or shall I spend the money to send them all back and get the M1-301s?

M1-301:
Weight: 1.3 lbs
Anti-Drain Back Valve: Yes
By-pass Valve: Yes
Filter Height (in): 3.81
Filter Outside Diameter (in): 5.75
Filter Style: Spin-on Canister
Filter Thread Size: 3/4"-16 Thd.
Filtering Material: Synthetic fiber blend filter media
Gasket Material: Rubber
Non-slip Grip: No
Removal Nut: No

M1-303:
Weight: 1.25 lbs
Anti-Drain Back Valve: Yes
By-pass Valve: Yes
Filter Height (in): 3.81
Filter Outside Diameter (in): 5.75
Filter Style: Spin-on Canister
Filter Thread Size: 13/16"-16 UNS
Filtering Material: Synthetic fiber blend filter media
Gasket Material: Rubber
Non-slip Grip: No
Removal Nut: No

Thread size/pitch is the ONE thing that must be the same!

Totally different threads:
Thread Size/Major Diameter/Threads per Inch(TPI)/Tap Drill Range/Tap Drill/Tap Drill Decimal/Theoretical % of Thread
3/4-16 / 0.7500 / 16 / 0.6820 - 0.6908 / 11/16 / 0.6875 / 77.0%

13/16-16 / 0.8125 / 16 / 0.7450 - 0.7533 / 19mm / 0.7480 / 79.4%


Send them back and swap for the right filter. :wink:

Bypass pressure could be the other difference but that doesnt matter since the 303 wouldnt fit anyways.

Amazon doesn't charge me to return stuff - they send a printable label, and send UPS back to get it. One big reason Amazon Prime is great.

Agreed! .. Sent them back, and getting a full refund. Then I'll order the correct ones and have them sent.

Thanks!
