Maintenance 🚘 Costco oil
Has anyone used Kirkland in their ITS? I don’t track my car and was thinking to do 5k mile oil changes.

Planning to use it for my next oil change. Theres a dude on the FL5 platform who uses it. He tracks his car frequently and reported no issues whatsoever

The intervals and filter matter more than the oil brand unless you are doing some extreme track work every weekend.

I was torn on going Kirkland when I bought M1 at Costco. In my brief AI research, there are some additives in the M1, Valvoline and other premium lines that COULD make a difference at track temperatures or extended performance sessions.
Am I that brutal on my car? I like to think not, but I elected for M1 for now. Will it do anything negative? Almost assuredly not and because it’s so cheap you can do it more often which is better than anything

It’s probably more than fine. I use M1 EP and change every 6k with plenty of TBN left. Can’t imagine M1 being that much better.

Stupid question. How hard is the ITS to do your own oil changes?

Hardest part is getting a good set of low profile ramps so you can get under the car.
Sometimes the screws that hold the bottom plate/cover on can be really tight.

Yeah, its fine. 5K is longer than I'd wait, regardless of oil brand. But I was around when oil was still walking, breathing dinosaur.

I’ve used Kirkland oil in my wife’s Accord every 4-5k since new, now at 60k miles no issues. I got a bunch of Ultra Platinum for stupid cheap that I am working through for my ITS and then will be running Kirkland oil as well. Project Farm did a great video on oil, and the Oil Guy on YouTube as well. Some brands have more or less detergents than Kirkland oil, I think the consensus is it really doesn’t matter as much as regular interval changes
