I did do this on the last change but almost forgot those need to be changed as well. Picked one up from the dealer last night. Thanks for the reminder.

If same, repeat.

The problem with this is not knowing how much was in there. I was scared of overfilling, so I just swapped it out.

My recommendation for you here is to get the Fumoto valve, and send a sample to Blackstone for analysis when you do change the oil.

I DID have a bit of gunk buildup on the OEM plug when I swapped it out. I did all my fluid swaps first thing when I got the car. This is now my second oil change, and no gunk on the new drain plug. I would send in the oil but I'm lazy and overwhelmed with work to put in that effort.

get some neodymium magnets to put on the outside of the oil filter.
It all gets stuck in the filter and you can re-use them on the next filter.

Interesting, never heard of this one but it makes sense. Would this restrict the oil flow?

That's a shame, I love nipples.


Allright, here's the verdict. I swapped the oil out last night. There was still quite a bit in there, but I'm sure we'd all agree it's considered low for these cars. I had about ~4.8 qt drain out and it was pretty dark. There were no signs of leaks whatsoever. I took off the under panel and there wasn't single drop to be found. I guess these cars just eat oil? My driving habits: DD, no track use, daily stop-n-go commute both ways in LA traffic so I don't even get to open it up all that often, but I do drive "spiritedly" on the weekends when there's less traffic. I could count on one hand how many times I've taken it to redline. I WAS checking my oil often after my first change but will admit it's been a good 4-5 weeks since the last time I looked. I know, I know, shame on me. Life just got in the way.

I guess considering how much oil was missing, I might cut my oil change intervals in half. I was going by the recommended 7500 mile interval, but it was 5k since my last change and it looks like it was overdue. Also going to add the Fumoto Drain Valve to my wishlist for the next change since I'll be doing them more often. I did like the Greddy Mag Plug while I used it, but seeing that there was no gunk on it this time, quicker swaps seem like the better deal.

I also experimented with the dip stick a bit more since I knew it was full. I can get a proper reading now, but it's not consistent. I still get oil only showing on the edge sometimes, following the exact same steps. I'm going to look into reviews before buying FT86SF's dip stick. I usually shop from them the most, but that dip stick just seems way overpriced.

Thanks for all the help everyone! I didn't want to seem like a total noob since this isn't my first oil change, but this flippin dip stick had me stumped.
