I recently purcahsed my first 911, so bear with me if the following question seems a bit dumb.

I have been running my 911T (72 2.4 mechanical injection) on 93 octane rating fuel with no problems. Reading the owners manual I noticed it specifies the use of 96 octane rated fuel.

Will the use of 93 octane damage the engine in any way? Are there additives which may be of benefit? Is 96 octane available at any of the large chain gas stations? Anyone have a recommendations to make?

Many thanks,
