I recently purchased the 2007 Camry XLE. Should the grade of gas matter? I recently filled it up for the first time with regular gas and it seems to be performing worse than it used to be.

I only put premium in mine. When I bought it, they said that I could do regular but it seems to perform better with premium.

Just FYI "Research Octane Number" and the octane number they (Toyota) used with their testing/research is different. I know, its confusing, I use to think the same thing. Research Octane Number, or RON, is actually a certain octane classification standard. The RON rating system is used in other countries (which is why Toyota list the RON in the manual). In the US, our octane numbers are obtained by averaging the RON and MON (Motor Octane Number, yet another fuel octane specification).

Same engine in the Lexus ES 350 which calls for 91 and squeezes another 4 HP with 91.
No way Toyota execs would want to have a Camry need premium.
It's a economy car and that would turn off potential buyers.
So it's 87 which does the job.
I like to have the best performance so I go with 91 or 93.

Different compression ratios for the ES350 so it needs 91 but you can use 87 it won't knock.

Same engine.
Same compression 10:8.

The 2GR-FSE has higher compression.
The 3.5-liter V6 in the GS 350 and IS 350 models augments port fuel injection with a direct-to-cylinder fuel injection system. The direct injection provides a cooling effect in the cylinders, allowing the higher compression ratio that results in greater efficiency and power and enhanced drivability. All Lexus models are certified as Ultra Low Emissions Vehicles or better (ULEV, ULEV II or SULEV).

As far as the Camry and ES 350 ....
"BTW - you'll note two HP ratings for the 2GR-FE at 268 and 272... They are in fact the same engines. I've been dealing with octane switches for years in 2-stroke applications, the Camry and the ES both can sense and adjust automatically to fuel/octane quality... The difference in HP rating is pure marketing especially considering the following disclosure present on Lexus.com and not Toyota.com "Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease." So, to get 272 out of the Lexus fitted 2GR-FE, you need to use premium fuel."

http://www.clublexus.com/forums/showthread.php?p=2176310


2GR-FE
The 2GR-FE is a 3.5 L (3456 cc) version. Bore remains at 94 mm but stroke is reduced to 83 mm. Output is 268 hp (200 kW) at 6200 rpm with 248 ft.lbf (336 Nm) of torque at 4700 rpm. This version features Toyota's "dual-VVT-i", variable valve timing on both the intake and exhaust cams.

Applications:

2006 Toyota Avalon
2006 Toyota Aurion
2006 Toyota RAV4 V6
2007 Toyota Camry V6
2007 Lexus ES 350
2007 Lexus RX 350


"The 3.5L V6 engine used in the '07 Camry is exactly the same engine used in the '06 ES 350. Both "versions" use knock sensor transducers (piezo-electric microphones which pick up the first hints of "knocking/pinging" before human hearing can distinguish such) screwed into the cylinder banks to feed the information to the engine control computer to tailor the ignition advance tuning on the fly. But the ES 350's engine is rated to 4 hp more. Why the difference? The ES 350's recommendation to use 91 pump octane vs. the Camry's recommendation to use 87 pump octane."

Same 10.8:1 compression ratio... The ES and Camry engines are identicle.

The ES/Cam and the IS is another story.

So 91 is Super and 93 is premium? Would 93 be overkill?

FYI - I asked because I noticed the difference. I am not sure what the dealer put in when I brought it, but i would tap on the gas and the car would go flying. :eek:

I put in 87 regular and the car was a lot smoother, but I noticed the performance decrease.

Jet Fuel, 106 Octane!!:rockon: :banger:

Just kidding, normal 87 here but I would probably go mid-grade on a road trip to stretch out the tank.

Since gotten the car, I only use Premium (91) in the car. The gas brand will goes as followed

1) Chevron, in case no Chevron and I REALLY need gas
2) Shell, in case no Chevron or Shell and I REALLY need gas
3) Mobile, in case no Chevron or Shell or Mobile and I REALLY need gas
4) Philip 76....
5) Last resort BP or Arco gas...

Unless i am totally out of gas and non of the above exist, I will put enough of other brand to get me to the next nearest gas station where one of the top 3 option exist.

I mainly use Shell 93.
There really isn't much 91 available in NJ.
Sunoco has it.
No Chevrons in my area.


Shell and Texaco are the only 'top tier' fuels in my area.

I guess due to the California strict air emission, the best we got is 91. We used to have 93 and if memory serve me right, there was a point we had 101 or something like that..sadly 91 now...
