As gas prices rise, will you deviate from Premium?
Just curious- Gas in certain markets in FL is approaching $4/gallon for Premium- Regular (87) is around $3.29 and Mid (89) is around $3.49. I've never deviated from Premium but wondering what others think.

difference between premium and regular is 70c/ga (that's if someone is crazy enough to put 87 in the LX).
assume someone drives 12k miles a year in the LX, and gas mileage of 13mpg. i round it up and that means total cost difference of about $650.
that on a $90-100k car and total gas cost of $3700, sounds pretty insignificant for any owner to worry about

I have seen so many discussions on this topic in both LX and GX forum. Never in the past wanted to inject my 2 cents and felt this is not really a topic that will offer much of benefits to anyone. But seeing this topic in LX forum over and over, I felt it is almost obligated to say something, and what I am about to say is just my personal opinion on this subject, no meaning to offend anyone. If anyone felt been offended, let me offer my sincere advanced apology first.
First of all, it is your vehicle and you are entitled to do whatever you would like to do! Manufacturer do put out the specs for the reason. Whatever the value those specs mean to you is also entirely up to your own value system. We all know technology today has been advanced to the point will make the best decision in terms how drivetrain performance the best. I have no doubt that either 87 or 91 or 93 or even 100 aviation fuel will run the engine without you notice any difference. But, for anyone who decided to buy a nearly $100K luxury full size SUV as Lexus LX570, shouldn't even consider which grade of gas to put in due to the difference of the costs. If the costs of gas is a such priority to you, then this is certain a wrong vehicle for you, period!

It's not so much about money. Maybe many users feel bad that they pay more just because Lexus decided to require premium in LX 570 for marketing purposes. Based on all available data (including ih8mud forum), 5.7 V8 in LX is absolutely identical engine to 5.7 V8 in Land Cruiser (which does not require premium fuel).
I personally won't switch from premium, although I personally believe it would make no difference given it's the same engine as the LandCruiser. It's more of a mental dilemma that makes me question myself a bit when the delta between premium and regular is currently around $.70 when it's typically half that (or less). When the delta is this large and I know it's the identical engine to the LandCruiser, it does make me wonder if I'm being foolish.
Sorry if I resurrected a topic that has been discussed ad nauseam - wasn't my intention.

Already made the switch a year ago, because premium is about 70 cents a gallon higher here, at 13mpg, probably saved about $800-1000 so far.
What helped for me was a report on this forum (it's the 5+ page thread) where someone reported over 100,000 miles so far on regular with no problems.

BTW, there is a similar thread on GX forum. I would bet that it will be similar to old threads. People on GX will mostly conclude that premium is necessary. We (LX owners) will conclude that regular is probably fine :-)

My wife drives the LX and I drive a 2017 Toyota Tundra for work. I asked the Lexus technician why one wants premium and the other doesn’t. He said, look at the emblem on the hood. That’s the only reason. The engine in my Tundra and the engine in the LX are exactly the same. The technician said if you like throwing money away, keep using premium. I’ve had two Tundras before this latest one and put over 250,000 miles on each one. I never had one issue with either one. Regular oil changes, tires and brakes is all those trucks ever needed. They ran just as good with 250,000 miles on them as the first day I bought them.

We will never know the truth. If Lexus admitted, that the engines are the same including the software, they would be in a risk of a class lawsuit.

It's just anecdotal evidence. Some have been posturing that there could be wear issues, but there's a report of 100k+ miles on regular on a 200 LX and another person reported over 230k miles on 87 octane on a 100 series LX that also stated premium required.
