If your check engine light is off & in working order, (insure it is on when you 1st turn on the ignition switch) it may be injector or sparkplug related. Put injector cleaner in gas tank & then fill tank with Chevron premium. This is designed to clean fuel system & combustion chamber in cylinder heads. The debris that is cleaned can get past piston rings into the oil sump so you should change oil soon after that tank of gas is gone. Replacing the sparkplugs should improve efficiency also. Search this forum to decide which oil to use.

The check engine light is ok and I changed the oil almost 2 weeks ago. I used Mobil 1 0w-40. I also have lucas oil injector cleaner I can use, I don't know why I didn't think to put some in the tank. I haven't been using chevron gas though it's expensive. Since I got the car I've been using arco 91 premium.

What's your elevation? Can you not get 93?

No gas smell and no leaks. I probably would've noticed it when I changed the oil. The engine light is also fine. Are you asking why I'm shifting at 3.2k? What is cats? Not sure I've heard that before.

Ok I saw the other posts while I was typing. Last thought would be to not shift until at least 4.5k and get your car off that knock sensor. At those RPMs and low quality fuel your timing could be retarded from lugging the engine. Lugging this engine is worse than revving it up due to load on the engine.
Cats are catalytic converters.

Sorry I messed up on the quote thing and had to fix it. Wouldn't 4.5k burn more fuel not helping with mpg?

So that's why they all drive teslas when they want to go fast!
I honestly did not know that such a socialist thing could happen in the land of the free  . (I kid, however I do enjoy my right to 93 octane, no front plate, and no emissions test, then I regret that right when a truck carrying a confederate flag "rolls coal" across the intersection.)
