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?

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 Style: Spin-on Canister
Filter Thread Size: 13/16"-16 UNS
Filtering Material: Synthetic fiber blend filter media
Gasket Material: Rubber

Will not work send them back. With different threads they will not screw on. Must be a proper fit u do not want them to leak sorry

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.

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!
