Which octane is best for the 3S-FE engine? Options

[Authentic]

Hey everyone,

So I've been on this forum for a little while now and I've figured solutions to most of my questions from seeing previous threads, however I couldn't get the search to work for this particular question I have.

So for the people with the 3S-FE engine, I was wondering which octane you run. I have been using 91 since I bought the car in November, and my Dad said that he ran our old 5th Gen Celica GT-R (3S-GE I think) on 91 also, however I decided to try 95 today since I was driving on the fuel light. I had a short drive home from the petrol station so I haven't had chance to see any difference yet.

So yeah, let me know which you use and feel free to yell at me if I've done something wrong, cheers.

I'm running a 3S-FE in my Curren. I found that when I put 95 in it, it seems to drive alright but it felt a bit rougher when I went to turn it off, like it was 'running-on' a wee bit, when I reverted back 91 the car felt a bit smoother. That's just what it feels like in my car but it could well be different for you.
