It drives me nuts!
Every inflatabe tire uses a schrader valve same size same threads.
Yet every engine uses a different oil filter, same sizes even have differnt threads and to make matters worse every manufacturer has their own naming/numbering convention. Fram's FU123 is a Wix 69BFD. I had 70 different cross references for one filter I was looking for.
What is the logic behing all the confusion I have so many miss matched filters brand new but unreturnable becausr my greasy mitts were tryong to install metric into standard threads.
Can they come up with a standard numbering system, diameter and thread. 0-1 liter engine - oil filter #1, 1-2 L #2, 2-3, #3, All same diameter all same thread you could substitute a #3 for a #2. All the coffee cups at 7-11 some how use the same size lid!
I've never bought the wrong oil filter.
Standardization isn't something used in the Auto industry except in some companies like Mercedes that standardizes a lot of their stuff or at least they used to. It's a money thing along with planned obsolescence
This more or less follows into the category of cutting wood and such for a project. Measure twice, cut once, unless you want to waste time and money.
I stick with OEM filters, or at least the same brand for every change. I've also memorized my regular use vehicles' oil filter sizes. FL-400S is my Ford Ranger's filter and FL-500S is my Mustang's. I believe my girlfriend's EcoBoost is an FL-910S. I'd suggest doing this from now on for your own vehicles.
Every inflatabe tire uses a schrader valve
and every gas filler is the same diameter. It's because the suppliers of gas and air decide the size.
There is no incentive for two car companies to make the same size filter. They use whatever suits them and the engine.
every manufacturer has their own naming/numbering convention.
and they all provide cross check tables to look up the correct one.
But when buying from retailers, you ALWAYS find filters by vehicle anyway, not by filter part numbers.
