Good point, looks like they continuously improve formula and bottle designs like engine oil formulas.

Here is the latest - best results so far. I'll have in a few months the PUP 0W/20 6 track days on API-SQ results in. The car did not go over 217F water temps and we ran it with two drivers 2 track days 10 sessions per day 25 min per session. The thinner oil does really help keep the car cool...

Looks like this is a newer bottle version - which says "New and Improved Formula" - I'll maybe send in a virgin sample to get it tested or just take another drain at 6000 miles and see how it performs. The newer bottle style looks like it was circulated in ~2024 ( Need to confirm ). I assume...

Here is another interesting observation after racing on the latest MTF transmission fluid. After the first flush the transmission felt much better and after the second flush it felt even better, and now I'm wondering is that what we all should be doing - flushing out break in metals during the...

Here is the latest Blackstone results from the transmission fluid. This was about 10-12 track hard track days - 6,642 miles since first change with MTF - 10,442 total miles on car. It was much better results than I expected vs first change. Flashpoint 445F. Has Honda changed the...

Excellent! Thanks!! Here is what I am deducing high level from that data: 1) Flashpoint 375 down to 325 - Inline with heat 2) Iron 2 up to 106 - big jump - real wear metal in oil 3) CST 100c - still in grade - 6.96 down to 6.54 4) Silicon 3 up to 26 The first transmission fluid change - I...

Here is my Blackstone report after 3800 miles with the Factory fill - Tracked mostly 80% of those miles at Laguna Seca. In two weeks we will have the 10,000 mile report, and it was also mostly 80% driving to track and racing and back into the garage. I will drive 4 track days at COTA and ~2000...

I simply asked: 1) What is the transmission fluid change intervals for number of track days with or without oil coolers. 2) Does anyone have Blackstone used transmission oil analysis ? I removed the AI video summary to be respectful to you, which simply summarized the video on the Honda MTF...

How often ( # of track days and miles ) are you guys changing the transmission fluid with and without a transmission cooler? Without a transmission cooler: every 3–4 track days, or about 2,500–4,000 miles max With a well-designed transmission cooler and actual temp monitoring: every 4–6...

Which higher grade transmission fluid ? And do you guys have any transmission fluid analysis ?

What do you recommend stock setup for change intervals for heavy track use every six track days or every three track days and change it with my engine oil?

For heavy track FL5 owners, who see over 80% track time - how often are you changing your transmission fluid? My car sees about 80% track time - it's hit 10k miles - I did my first transmission fluid change with Honda MTF at 3300 miles and I just did one at 10k miles and it smelled a bit...

Forgot is anyone getting a black stone virgin oil sample of pennzoil ultra platinum 0W-20 API SQ?? I’m finally sending the API SP version to black stone and filling with SQ.

They do really help steering feel, sharper, more glued to the ground, and they do feel stiffer than the 4s. Never tried them in rain. Here’s a review of the car on cup 2s canyon driving.

The cup 2s were good but not worth the money — only 1.5-2 seconds faster than 4s at COTA

A little hack to get them half off… I burned through my 4s’s on a few track days and Michelin credited me and got the cup2s.

The first 10,000 miles, with oil changes every 2500-5000 miles you will still be flushing out break in wear metals.

My goal is to change the gear oil every two oil changes, but want a quicker way to do it without taking the airbox out every time, and my understanding is the dealership has a method to do this. Wondering has anyone tried to simply fill via a syringe via the 10MM check bolt and drain it from...

Amazing progress ! Regarding your question “ My question to you John- How did you manage fitment for the plastic cover that goes over the hatch latch?” Can you send me a picture - thanks ! Great work !!!

I believe I had some notes here in the forum. I did order an amazon panel remover tool kit that was extremely helpful with removing panels and the fenders etc.
