last night I drove 205 miles in my tc, filled up before i left with premium. only used a quarter of a tank.

two nights ago i did the same distance using regular and 205 miles used 3 quarters of a tank... that was enough to sell me

 

I'm filling up with regular, should I go premium??

 

I run plus in my tc and occasionally put premium. It does feel different and I find that the gas burns ALOT slower...

 

also the car drive feels smoother

 

people, the car is tuned for 87 octane. put 87 in it. do not waste your money.

any benefit you think you are getting is placebo.

did you know snake oil can also make you look younger?
