Gas: Premium vs. Regular advantages, disadvantages (merged threads)
The present - and future - price of gas is no longer a small matter. Have all Lexus' always “had” to use premium?
I've had cars that "suggested" only premium where I used regular with no bad effect. The automatic spark always seemed to sufficiently retard to avoid pinging. Obviously you lose some performance but usually that’s immaterial. I've never had a Lexus, but I'm sure that they have this "auto-correct" timing, too.
I know there will be a rush to respond that: "if you can't afford premium then you can't afford a Lexus." So, there, I've said it. Now it won't be necessary to tell me that. But, just having money and throwing it away are two different things. (And, yes, I AM a cheap skate.)
Bottom line .. has anyone tried regular in the current LS430's?

Direct injected engines run at high compression..
near 12 to 1. Your fuel efficiency can drop 5 MPG also with low octane. So as a cheapskate you should by 91 Octane or higher and won't have to worry about less performance or worse.... engine damage.... and get superior fuel efficiency. It's actually cheaper too..

Using Regular Gas and Chevron vs Costco
I was told by my sales person that I could use regular gas in my 460 LWB. However, I would get about 10% worse mileage, which is slightly more than the difference in cost between premium and regular. He also suggested using Chevron (I'm in the SF Bay Area) and not use Costco premium. The Costco is about 30 cents less per gallon - including the CC and membership rebates. Any ideas? Thanks.

Crude oil goes to the refinery. Regardless of which company provided the crude, its all mixed together. When refined gasoline, be it regular, mid-grade or premium, leaves the refinery, it goes into a pipeline. At the end of the pipeline it is distributed to whoever buys it. Now at that point a particular company may put certain additives into their gasoline which may alter its characteristics, but 93 octane is 93 octane no matter whose brand it is. Its the very same gasoline.
In short, Costco 93 octane, or 87 octane, is identical to any other brand's 93 or 87 octane. It all came out of the same pipeline. Only the additives may, or may not, be different.

Chevron fuel has Techron additive in it. It's very good. Around here, BP 93 is the best fuel. We don't have any Chevron Stations. I'm not sure what octane Costco premium is. I will look next time I'm there. I've never purchased fuel at Costco...
