I've been getting between 17.6 and 18.1 MPG around town in my 2001 LS
430, I was getting between 18.6 and 18.9 with premium so there is a
slight MPG penalty with mid-grade. My mileage is pretty consistent
except when I take a highway trip of 30 minutes or more during the tank,
when my tank MPG goes to about 20.1. On long trips where the entire tank
is highway, I get about 25 MPG if I don't use the cruise control, and
around 24 MPG if I use the CC. If my wife or kids drive the car, fuel
economy goes down by at least 1 MPG.
I suppose if I slowed down and wasn't passing people around town all the
time and kept my highway speed below 80, I could probably get a little
better fuel economy, but old habits die hard.

I've been entertained by this "regular gas" thread
recently, and I have two small comments.
1). This is the first time I've ever seen my suspicions
corroborated, that say I can get better fuel mileage
without a cruise control, that with one. (Noted
from the previous comment(s)).
|
I think that the cruise control tries to make too many throttle adjustments
to maintain speed, instead of letting speed creep down a little on uphill
stretches and build up on downhill stretches.
| Quote: |
2). My other suspicion is that the performance of
these vehicles using regular/premium etc. is a
lot more related to *actual* gas in the ground,
rather than the vehicles reaction. IOW, the real
octane in the ground, as well as, the age of the
fuel, temperature, holding tank age/condition,
dispensing equipment condition, etc., etc.
Additionally, I was recently told by a local gas
company representative that a 6.5 ounce variance
on a 10 gallon volume, was allowed to remain in
compliance to local weights and measures.
That seemed quite high to me, but if correct, will
certainly affect mpg calculations. Especially, if
one frequents different stations.
I have no information with which to back up or refute that suspicion, but I |
tend to agree.

Sounds reasonable. Let's see...128 ounces in a gallon, so 1,280 ounces
in 10 gallons...
Dividing 6.5 by 1280 gives 0.51% (approximately). Half a percent
relates to about $0.02 per $4.00 gallon, which seems like a fair amount
of tolerance, given the relative crudity of the dispensing system
(accuracy of the meter, gas remaining or not remaining in the hose,
etc.) Actually, on thinking about it, I'd be pretty happy if the pumps
at the local station are actually that close.

Yeah, at $.02, it doesn't sound like much. A lot less
than the 6.5oz/1,280oz ratio. At least to me.
But, consider:
Fuel dispenser volume shorted on a 10 gallon fill:
(200 mile trip / ((1,280oz - 6.5oz) / 128oz)) = 20.102080mpg
Fuel dispenser volume equal on a 10 gallon fill:
(200 mile trip / ((1,280oz - 0oz) / 128oz)) = 20.000000mpg
Fuel dispenser volume longed on a 10 gallon fill:
(200 mile trip / ((1,280oz + 6.5oz) / 128oz)) = 19.898950mpg
Of course, your manual calculation would always net to 20mpg.
But, behind the curtain, the values are quite(relatively speaking)
different. |

Get real! 6.5 oz in 10 gal is about 1/2 of one percent. The error
here is absolutely trivial, and of no consequence to your
calculations.

The fuel recommended for my 05 RX330 is Regular. It was one of the
considerations I had when I bought this instead of one of its
competitors.
By the way, took in my RX for Service, and the service advisor said
that they'd put tire pressure at 35 psi (manual says 30 psi). They
used to put it at 32, but I guess with gas being where it is 35 is
better! |

Like buying Kroger's "Select" grade of beef, hamburger so lean it looks
like sausage and store-brand soda and canned goods? Thanks just the same
but my kids said they don't like to eat at your house. Everything tastes

In my opinion, the Lexus owner who pours 'regular' into a tank clearly
marked for 'premium' is the same petty cheat who buys cheap booze at the
liquor store & pours it back into the expensive brand-name bottles. Trust
me, we can tell the difference and so too can your car.

Lexus ownership is no symbol of wealth or achievement. Anyone with good
credit can buy a Lexus. In fact today the dealerships are so hungry to
make a sale to anyone with a heartbeat that you don't even need good
credit. However, "affording" it is an entirely different matter. If Lexus
ownership means tightening the belt to shave on the quality of other goods
and services that comes along with the price of the ride, then in my view
you should be driving a Hyundai. People like that don't deserve a Lexus.

holy crap dude. You've got serious anger and/or envy issues. Get over
it.
FWIW, our taxes alone is more than triple the national income average
but if my car doesn't require premium to run efficiently, then I'll
use less.
Wealth gives me options. Options come from knowing where to spend
my money and where not to. Given a choice, I'd rather spend the money
on good and frequent synthetic oil changes rather than high octane
fuel when it does nothing for either performance, longevity or mpg.
Maybe it's *you* who thinks it makes you look big and important
pouring high octane in your tank at the gas station. I don't have
such an identity issue. |

It's not really a question of affording or not. This is my 3rd Lexus and
I've owned 2 Porsches prior to that. So obviously that is not the problem.
It's a valid question as to whether it is wasteful to enrich the oil
companies if it is not really necessary. Why throw away money or overpay
for anything? That would be just stupid.

Thanks for all your very professional replies to this and other
newsgroups.
FYI-
1998 Sienna, 3.0 V6, 215,000 miles
Last Xmas I took a little trip to West Palm Beach, FL from the
Baltimore, MD area. I drove straight through each way. I noticed that
my best fuel economy was achieved on 87 Exxon purchased in North
Carolina, in both directions. I suspect the fuel blend is different
there. I get nearly the same mpg (22-25 highway cruising) from the
Sienna (on 87 octane) as you get from the LS but I've gotten better
(27/28 mpg from several tankfuls) when I was driving across the high
plains of Wyoming at around 75 mph. For commuting I can't measure a
consistent benefit of higher octane fuel but on the highway with a
loaded minivan premium does deliver more mpg.
YMMV |

My owners manual states 87 octane minimum while the dealer mechanic
recommended 91-93 octane (I'm not biting the semantics thread of
premium/super/regular). I have run both 87 and 91-93 and have let the car
decide which one and it prefers the 91-93 octane. It gets slightly better
mileage (both city & highway) and did not have the hesitation problem which
thread was so prevalent the past couple of years. The RPM's are also lower
for equivalent MPH.
I don't know about the other posters in this thread but I agree with you in
that many people I know driving the "upscale" autos cannot afford to
maintain them or don't know how to maintain them. I am seeing many more
posters asking for help and having responses telling them to read the owners
manual. A good friend who is a BMW mechanic (he specializes and dealers go
to him when they get the tough ones) will not service a new customers car
without reviewing their service records for oil changes and other periodic
required maintenance. No records, no service. I asked him why and he said if
they could not afford to perform the required maintenance then they did not
know how to properly maintain a car and he did not want to have them as
customers.
If you cannot afford the gasoline, you cannot afford the car. Period.
