96' Corolla gas octane info needed?

Regular (87) is what the manual says --- any other on that year is waste of $. Newer cars with more advanced computers will give more power with higher octane but not a 96.

Use 87 octane in North America (R+M/2 octane measurement).

Paying more for gas will not provide extra mileage, so you are effectivly throwing money away to buy a higher grade than the engine asks for.

Thanks for the help. By the way, does anyone recommend those little containers of STP gas treatment. They are supposed to clean out deposits in the tank.

That stuff is probably good to use. I do not suggest you buy a case and put some in at every fill up, but when you change the oil, it would be good to add a can of gas treatment or two, as a maintenance item.

Only gas additive that I've found to work is Chevron Techron for cleaning the fuel injectors. Note - Newer cars do benefit from more poser and higher gas mileage with higher octain gas -- their computers retard/advance the spark depending on the knock sensors - so if you need the extra power for carring a full load, going over mountains or towing a trailer the higher octane does make a difference.

I could argue that, esp on smaller engines.

With my Corolla 1200, I got 39 MPG with 91, 34 with 87 With my Corolla GTS, I get 36 with 93, 31 with 87 With my Tercel I got 45 with 93, 39 with 87 With my 87 Corolla 4DR (carb'd) I got 45 with 93, 36 with 87!!!

Also, I have NEVER had a knock or misfire of any kind in any car I bought new and used over 90 octane. One exception:

Yup...Techron is good, and if you have Chevron in your area, it's already an additive...

What about just plain, balls-to-the-walls FOOT TO THE FLOOR???

I agree with Wolfgang about Techron being a good product. The Toyota brand stuff available from Toyota dealers is also very effective. Make sure you follow the instructions on the container, especially about using it up in the specified time.

I would not use fuel additives more than once or twice a year because some of them have a tendency to eat flexible fuel lines. I've seen gas turn almost black because the additives were dissolving the flexible fuel lines.
