A more balanced view of a oil filter

good point, i never thought of it that way. hybrid engines work a lot less than gassers, but start thousands of times a day. i wonder if this creates less wear, or more?

 

i do 10, after the initial 5. but someone mentioned not doing the first oil and filter until 10, so the pistons could bed in. i don't really understand the mechanics.

 

What is the second gen interval? I keep forgetting you've got 2005.

 

second gen is 5,000 miles in the usa. but manufacturers recommendations are not about best practices, they're about getting through warranty with no claims and proving that they're products require less maintenance than the competitions.

 

On third gen there's only the paper element being replaced, it's in a permanent, reused canister. There's a guy here, doing his first oil change himself, after dealership oil changes: unscrews that canister, and finds NO FILTER in there. Wonder what that does. He was pretty level headed about it, talked to the dealership, got some documentation, that they agreed it was on their watch that it happened.

The 3rd gen filter-only change design seems prone to this absent minded mishap: I've caught myself twice now, just about doing the same thing. You unscrew the canister, tip out the oil, shake out the filter, peel off the O-ring, put on a fresh O-ring, busy, busy

Too bloody easy to forget, lol. If the engineers could have designed it somehow, so it was impossible to screw in without the filter element, that'd be good.

Sometimes si, sometimes non. At least I hope so, that once in a while they listen to their engineers. I think it's very true that they'll establish an interval, and then ten years and another generation, they need to revisit it, just due to more knowledge, and maybe oil improvements.

With the transaxle fluid change interval, the engineers were NOT in on the discussion, or got steam rolled, lol.

 

I'm not sure what that first sentence means in practical terms. If there is a clog, the flow decreases and the pressure after the clog goes down while the pressure ahead of the clog goes up. So what point are you trying to make ?

And an automotive oil filter removes ONLY solids or gels.
Anything that is dissolved in the oil.......varnishes and acid.......are not affected.

 

i don't like the paper element in canister either, but sinc it's there, why not make it so you can lift out the element, without getting oil everywhere? this would make it much easier to change the filter whenever you want.

 

I don't mind the current orientation. Once it's partially unscrewed you tilt it a little, oil trickles out in orderly fashion, none running down to your elbow, if you're at all organized.

 

The current census over at Bitog seems to point to the Fram Ultra as best bang for your buck and overall top performance for filters. It also has a very good flow rate. I really like Trd filters but the Ultra is much less expensive and seems to be a better dollar value. I'm using the Ultra XG3600 which is the oversize for the Pri. Pics of the insides are quite impressive...

I also use a filter mag....

any scientific testing done?

 

Hi Bisco, for what it's worth Fram has tested this filter to be 99% efficient for particles 20 Iso testing.



As for independent testing, I havn't really come across anything substantial. Here are some interesting oil filter threads from Bitog...

thanks dino, the reason i ask is, i purchased a fram cabin filter, and it was vastly inferior to the oem, just on looks and feel, no idea how the actual filtration is.

 

does bosch make a prius oil filter?
