Though not 10-20 HP.
Only 4 and a bit more torque.Still worth it.
You'll never convince the 87 users.
They spend big $$$ and buy a Lexus and then skimp on octane.
They know more than the engineers.![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
You can use 87 but to get the best performance and MPG,premium is the choice.

I use 93 in my 94 GS300. I havent changed the oil yet (just got it a week ago, changing it sometime in the next week). I plan to use Mobil1 5w30 full synthetic. Im used to using only Mobil1 full syn with 93 octane from my DSM's, so I dont mind giving the GS top notch products. No need to skimp on a few bucks now, because doing so will cost you more in the long run.

Not only that, but to preserve the longevity of the engine since it is high compression, the premium is recommended. The car ECU needs to see the extra octane to prevent knock like mitsuguy said. Trust the DSM guys, we know about knock and octane points ![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
