Never gave it much thought myself until I read the catalog.....

Physical size, thread size, with or without the anti drain back feature....probably more info but I don't have a catalog handy...

I did go look at a 51060 and a 51061 just to be sure I had the info correct...

Those are std length filters....

They also make a shorter length and a 2 quart "truck" filter.....

Some are labeled Extended Life....

I use the 51061 R on my engines and have for years.....Bought them by the case...

We buy from Filter One.....Nobody comes close to their prices and they ship UPS...

Only issue is they do a very poor job boxing filters for shipment.....Some get damaged or boxes busted up.....occasionally....

I don't use the R=filters they have a 51 Micron rating the 1061 have a 21 Micron rating
