Thanks for your honest reply 06LexIS. Your decisions are also base on your unique work experience. Good info here, I like it.
lobuxracer, Why does it matter if you can’t find the “special” oil in a little town on Sunday night? Don’t you know ahead of time when you plan on changing it? Or do you mean if you need to top it off for some reason? If that’s the case then you can ad Mobile1 since there are all compatible.

Yeah I know Mobil 1 is a polyalphaolefin and so is Red Line. But they have different additive packages, so in an ideal world I would never mix them. Some additives can be antagonistic. It's not as bad today as it used to be, but in the past there were potentially seriously bad consequences to mixing oils. I called Red Line and asked if mixing would be OK. They said we can't say for sure. I called Mobil and they said there's nothing to worry about since they're both PAO. I changed the oil in the car as soon as I got home, and decided to prevent this from happening again by using Mobil 1 in any car I use for long distance travel.

Miniaturising a mass spec to operate inside and engine might be a tad challenging. Ours took up about 500 square feet of floor space each, but they were spec'd for radionuclide analysis, not simple metal content analysis. We had more than one. There are smaller units available, but they are focused on organics, not metals.

I always get a kick out of these comments. I've never figured out why this "personal" info is considered so secret. It is some of the most publicly available info around. Same goes for license plate numbers. Why blank out a license plate number on the web when thousands of people see it on the road every day?

I would never expect Lexus to pay for repairs that result from my modifications. For example, I've toasted my OEM battery by leaving the car on with the engine off for extended periods of time while testing. I'm just walking out the door right now (weird coincedence) to go buy a new battery myself instead of trying to get it replaced under warranty.

Time to revive this thread. I got my 20k UOA done at Blackstone. Here's what it looks like. Interestingly enough, I used the specified weight and got a lower iron number than Gernby did for his 5k change. I also talked to Billy at Blackstone, and his comment was wear particles trump TBN because wear particles accelerate the wear process. He suggested I reduce my interval to 7k or so. After seeing Gernby's numbers, I'm not so sure if there will be a significant advantage to that. However, there might be an advantage to running a magnetic drain plug.

And I do Infosec for a living. I don't put my information anywhere I can avoid it. I've also been a victim of true name credit fraud. It's a PITA to get sorted out.

I would say once a year is the earliest you need to change. But you can definitely go longer. Miles are apparently the only factor you really need to keep in mind. And as Lance's analysis shows, you can easily go 10k miles, for sure 7500k miles...
I didn't change the oil in my Jaguar V-8 for 3 years (Only drove 8k miles) and when I did a blackstone analysis the oil was still in good condition with plenty of additive left...

First change was at 5k. Second at 10k. This is the result from the third load of oil.
