does anyone know whether an 04 ES330 can run on 87 regular gas? The manual says its ok but most people said no. Also, can I put regular 87 gas and an octane booster to make this work?

I know most of the over-the-counter products do not work. Anyone has experience with one that does work? THX

From what I understand (check your owners manual for confirmation), octane boosts are a big NO NO! I'm not sure of the reason, but this was discussed in another Forum on here. Do a search for more details.

Using a higher octane gasoline will get you better engine performance. You can get away with mid-grade. Others on here will have different opinions, but I usually put in super grade, as mine is not a daily driver.

BTW, welcome to CL!

In my own opinion, it won't kill you nor your engine. I don't recommend it though, cheap gas can often be bad for injectors and yes there will be a performance loss. If it isn't worth the extra $.20 a gallon to sacrifice those things, then go ahead. Otherwise, bite the bullet and press the 93 button.

Also, what MyfirstES said about octane boosters, just stay away from them.

I use seefoam in my tank every oil change.

i drive my 03 Es300 everyday (60 miles / day), I tried from 87-89-91 gas, from Shell, Chevron, even Arco (91 only) and the MPG still really really close, not that much difference (around 23-24mpg) and I feel the same power even though I'm using different brand or octane. Yes, maybe 91 is better for a long run, but it's totally up to you. I tried to use 91 full tank for about a month and got the same mpg / power w/ 87 gas.

Thank u so much for the real-life example. I am NOT cheap but my company will only reimburse reg (87) gas so I am trying to confirm this. I know that 99% of the octane booster products are junk. does anyone have real-life experience on some that actually work?
