This subject has been kicked around for a long time and at end of day use whatever you want. I use what is recommended by Lexus, premium fuel and a blended oil from the dealer. Lexus only specifies a 5W-30 oil weight.

The cost savings over the course of a year isn't really significant, but if I can have a couple of nice meals out with the wife using that savings it's incentive enough for me.

The 3.5 is also in the Sienna van, Avalon, and Rav 4 V-6. I may be missing some. 87 in my ES for 51K miles and still going strong.

I'm in the regular or premium makes no difference group. I've tried both a number of times on trips we take regularly to Blacksburg, VA that are about 550 miles round trip. I've have not seen a difference in fuel economy. The car runs just fine on regular. Look at the Toyota and Lexus specs on the engine, there's only four horsepower difference. I use Amsoil 0-30 for 10K miles and changing the OEM filter every 5K.

The ES will get a yearly change as I only will do about 5K-6K miles a year.

Just posted this in another thread, but I'll post here too.
I've played with 87/91 and while 91 is definitely better, I noticed the biggest difference when I changed from regular oil to Pennzoil Platinum synthetic. Night and day difference in smoothness and engine response. Less grumble, and more willing to leap to life. Totally worthwhile with an oil change using about 1.2 jugs of $20 PP oil.

This is the first car I have NOT used synthetic oil in many years. My last car, a BMW came with synthetic oil from factory and the free oil changes used the same type oil. If I decide to keep the Lexus at the end of my lease I will certainly change to synthetic. I have used Mobile1 since it first came out in the '70's.
