slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

Is it okay to mix regular octane gas with high octane gas?


There is no advantage in mixing fuels If the car is tuned to run on regular leave it at that as the computer has been set for that fuel. Check with a dealer and find the recommended fuel for your vehicle . By going to a speed shop that has the ability to reset you cpu to a higher/lower fuel rating you can retune the motor. But if you are running on the recommended fuel leave it alone. It will be cheaper in the long run

Been using 87 octane in '02 maxima for 1yr. have replaced oxy & nkock sensors. Is this due to low octane?


Ok the 2002 Maxima 3.5 requires premium fuel 91 octane. According to the owners manual for optimum performance use 91 octane, you can use 87 octane unless you get pinging sounds. Sounds like you just need to use the proper octane. Occasionally I will run regular 87 and can really feel a loss of power. When I use 91 octane the car is a rocket ship.

Does the 09 es350 need 93 octane gas or will it run on 87 octane


you should have a factory affixed sticker inside gas compartment cover listing premium fuel only or also listed in your owners manual. Otherwise if you notice that you're vehicle is making a pinging sound while accelerating or climbing a hill for instance then you may want to step up to 89 or 93 octane and try to avoid purchasing fuel with ethanol added it's **** and degrades your fuel quality/octane ratio

What grade gas should be used ?


You should always use premium fuel on the high conmpression V8 engine. Cheaper fuel can cause a PING, and possible engine damage. 87 octane is definitely not recommended at any time, but sometimes you can get by with 89 for a small period of time.

Gas mileage and power will both be down with lower octane fuel, so do not use it all the time.

CAN YOU USE REGULAR GAS IN A 2006 LEXUS GX470?


Only short term when absolutely necessary...

Your owner's manual says:
"
Fuel selection:
Select premium unleaded gasoline with an Octane Rating
of 91 (Research Octane Number 96) or higher for optimum
engine performance. However, if such premium type
cannot be obtained, you may temporarily use unleaded
gasoline with an Octane Rating as low as 87 (Research
Octane Number 91)."
