I put 93 in all my cars...It matters, try a tank, and tell me you don't feel the difference...Keeps it cleaner, and runs more efficient.

IT calls for 86 and above...I agree...86 would be fine...but if you want to put the best in your car, why not spend the extra 20cents a gallon??

I experience little minor things if I use 86 octane...but that could be because I always use 93...and I tried using the regular...poor starts, rough idle....intermittent starts...this are cars that request 86 and above...I have a GS400, calls for premium, I had a Z28, calls for premium...It makes a difference, don't knock it till you try it...

Give it 2-3 tank fulls, and go back, you'll notice the difference...
