We have a 2008 RX 350 and I have been using 92 octane but I have read several posting of other owners that use 87 and 89 is that ok to use?

Yes. Computer will retard timing to prevent any knock. You might lose a few horsepower and MAYBE ~1 mpg. I used 87 octane in my 2007 ES350 for 4 years and 70K miles with no issues and still got 32 mpg highway at 70-80 mph. New RX's have been released requiring only 87 octane.

I was hitting around 21 with mixed driving. Now I am doing great. 32+ mpgs!!! Of course that is because the RX is now in the back of the stable and the Miata has come out to play for the season.

Last night I refueled the 350 and it made me $70 poorer (for 323 miles). The average is about 19.5 MPG now. On the side note, my 450h can EASILY get over 29 mpg.

The first picture is city driving after fuel up. The second picture is highway driving (65-75 mph) after 60 miles.

my 2011 RX 350 get's 19 on the city and 23-24 on the highway.
i have switched to regular unleaded (87) and noticed to difference.
i guess members confuse the decrease in hp vs mpg.
Using 87 vs 91+ gasoline, in my opinion decreases the Horse power by 4
with little to no effect to the mpg.

i have 6,000 on my odometer.

Here is my last consumption in L/100km (France) with winter tires.
It was at the end of a trip on motorway (130km/h or legal speed limit)
The last line is 10l/100 km limit and the last 15minutes was from motorway toll gate to home/garage

I now have 9000KMs and am averaging around 7 liters per 100K (34mog us) in the city. My Highway numbers work out to about 9 liters per 100k.

I am interested with fresh oil and warmer temps what changes will be achieved. I use 87 fuel and do not try and hypermile even though my driving habbits have changed.

Hi Jairus

Excellent!
