Oil Filter - part number and where to purchase

I really do not want to start another 50-page discussion on oil changes but just wanted to share some info on filters for those who change their own oil.

First, the part number on the filter that is installed from the factory is NOT the same number as the replacement filters, for whatever reason.

The part number is 90915-YZZN1. You can pick this up at any dealer's parts department for about $5-6. I also realized that you could find them at some Walmart's and parts stores. Oddly enough, these stores usually charge more than the dealer ($6-7 or so), but it is still a really cheap filter. I will buy from the local AutoZone a mile from my house instead of driving across town to the dealership!

Look for this packaging if you are not familiar with the Lexus/Toyota branded parts...




Also, just a personal preference thing, but when I change my oil, I always top it up to be EXACTLY on the high mark of the range. Most places just get the level somewhere in the range and call it good enough. I am a little OCD about this, for a couple of reasons...

The oil level is only going to go down, so why wouldn't you start at the highest fill mark? And if you do burn/leak some oil between changes, isn't it good to know exactly how much - by topping it back up to the line?? And more oil is better than less oil. There is a good reason why performance engines have deep sump pans for more volume.

That said, NEVER overfill and go above the high mark. If you get the level too high, oil can slosh into the spinning crankshaft and become foamy/frothy - which does not lubricate as well.

 

To be entirely fair, oil level can go up. It's just not very common on gasoline engines unless there's something very wrong with them. I tend to agree with the rest of your conclusions, though.

 

Honestly I am not sure you really have any more information than in the original post of the pinned oil change thread.

 

Ahh, you are absolutely correct. Sorry for reposting this stuff...

 

Nah, all good. Probably a good reminder for some folks as well as new info for people not aware of the other post.
