Hi I am wondering which one should I put in my Toyota IST 2005 1.3cc?
Seems 91 is too low but 95 is too high?
Can not find any manual of ist even online...
Thanks!

Hi there,
Lack of specs and vehicle information is common for a Japanese import. It is generally accepted that most Japanese manufactured cars that are not turbo are able to run on 91. It might be best to ask Toyota also and see what they recommend. You can use higher octane fuels and see what is best for performance or the pocket.
