Well I'm gonna fess up!

About two weeks ago I got up early started up the A model and went cruisin'. Not much unusual yet. Then I remember I need to squeeze some juice into it. I roll into the servo, look for the unleaded pump and start pumpin' away. I look down and hear "gurgling", "gurgling" I think to myself....mmm that smells like "OH MY GOD ITS DIESEL!" I stop imediately to realise I have put about 7 litres in my tank. (gal and a half) I go inside and pay then I drove her home in disgust. A few wiffs of smoke out the exhaust but I think I have a ratio of about 7:1 or 8:1. From what I can tell, its just giving me some pinging. Driving her slow at the moment till I run it out. I hate laying off it. I was thinking about a squirt of that octane booster in this tank till it runs dry. Anyone else want to fess up to being such a dickfist?
