Not sure about the synthetic, but anything penzoil should not be put in a Lexus.

If you change your oil every 3k, that is more than sufficient for any oil. If you change every 5k, than a better oil brand should be used. If you're going to push to 10k, then better use full synthetic.

I do DIY oil changes so I use synthetic and change every 5-6k.

Just use the correct grade of oil and change it according to the owner's manual and you won't have any problems.

Yes even that.
