Not really that young. I am in my 30s. I feel old... Lol
Anyway the drive it like you stole it plan... Doesn't work. This car is getting embarrassing fuel mileage. I calculated last fill up at almost 6mpg. There's no way my work van gets more than double but it is...

I had a friend come over with a scanner. His brother and cousin works for the local Porsche dealership service department.... It didn't show anything was wrong. This tank has some Lucas fuel treatment in it. Hopefully clean out any dirty Injectors. As for 93 octane. I don't know any places in abq that has anymore than 91. Any sort of higher octane is special buy from the local muscle shops. By the barrel.
Yesterday I found a link to someone here who lives by me who was having bad fuel problems but I believe I was IP banned... So haven't read on it yet. I did clean my K&N filter. It was bad. PO had grease all over it. In it. All over the filter holder frame. It took hours to clean.
