Using non-spec filter bad?

[unDummy]

I've had no problems using Ford sized filters on Toyotas. Adds a little oil capacity and filter surface area for cooling. The FL1 and FL400 sized are good choices.
I'm thinking that the FL299(?) might actually hit a frame rail or suspension component if a motor/trans mount lets go. This will be for you to decide and measure.

You should NEVER mix threads regardless if you think it feels OK.

In reality, other than the OEM, there is no "SPEC" filter. All are simply supposedly backwords engineered. Why each brand uses differents specs makes you wonder how important it really is!

What Toyotas have people used with the FL-400S, FL-1A, and FL-299?

I used a few FL-400S filters on my '95 Corolla, 1.8 liter engine. They barely fit, but worked fine. I stopped using them after I noticed that it took a few seconds for the oil light to go off once when I didn't drive the car for a few days. That's a huge filter compared to the thimble-sized one specified for the car. I just got nervous about such a large filter that might drain if the ADBV didn't work.

I'm using the FL400s(3/4-16) filter in various dodges/plymouths/toyotas/nissans. Sure beats having to stock multiple PNs for the regular customers.

You should never mix thread sizes. This is asking for problems. There are oversized filters for most applications.

The PH3600 sized filter is a good oversized option for the PH3614/PH3682/PH4967/PH4386.

Sorry. The initial post stated that the FL400S filter was for the Taurus & F150 truck, and I assumed that this was true. The filter that fits these vehicles (equivalent to the Wix 51372) has a 22 x 1.5mm metric thread.

You need to index that for MODEL YEAR. The FL1A will fit a 91 Taurus that specs a FL400S as I believe both will fit an F150 of that year. The metric switch over was for later models.

I don't care ..all my vehicles can use the ST8A ..maybe even the larger one in Wix.
