Blackstone UOA results of break-in oil
#7
So, you did in fact run the original oil for almost 5,000 miles and the report came back good? I have always changed at 3,000 miles and was not sure about the recommended 5,000 mile oil change. With these facts, then 5,000 miles should not be an issue? Thanks!

Actually, like most manufacturers, Lexus has 2 recommended OCIs. The "regular" OCI is 7500 miles, and the "severe" OCI is 5000 miles. Once break-in is complete, I'm confident a good oil (Red Line, Amsoil, etc.) would be fine with 10K OCIs and maybe a filter change at 5K. However, I will probably just stick with Mobil 1 and change it at 5K or 7.5K intervals based on future UOAs (and no track days).

Agreed. I change my oil at the "extreme" interval because all of my driving is short, city trips (usually less than 5 miles) with lots of L.A. traffic and hardly EVER any highway driving, unfortunately. Sooooo, I'll be sticking with my Royal Purple/Mobil1 every 5K - it's just too cheap not to...

If you look online, you'll find the 5000/7500 mile option, but I'm pretty sure they screwed up and are presenting the information for the IS300 under the IS250/350 heading.
That being said, I doubt you'd have any issue running 7500 miles or more on a good synth.
On another note, I'm glad you went with blackstone on the break-in oil. I'll be changing mine out shortly, so it'll be interesting to compare the two reports.
