I noticed lately lots of "new" 1st time Grand National owners enjoying their cars, many get the advice to buy a scan master. Seems like some heed that and others do not.....
Here is yet another reason they should be standard equipment on your car.
I was below 1/4 tank and pulled into my local Enmark on the way home from work. I filled up with around 15 gallons of "Golden Premium" 93 octane. Later that evening I had to go on an errand and during some spirited acceleration I noticed the scanmaster with a knock retard of 3.8 (!)
I tested the theory with some WOT blasts and indicated retard each time although much less than the 3.8.
I went home and drained the tank into three 5 gallon jugs and went to the local Shell and filled up with 93 Octane Vpower. Blasted out of the lot onto the highway....No retard. More WOT blasts, no retard.
So the next day I am really thinking I will get no resolution but I go back to the Enmark and ask to speak to a manager, attendant tells me"Sorry not here, here is her number." I called no answer. So I went to the Enmark website and filled in a "Contact Us" complaint form.
Monday the district manager calls me and we have a conversation I explain how I know there was something wrong with the fuel and how I can monitor things going on with my car. He asks what day did you fill up? I told him the 7th. He then proceeds to tell me on the 2nd their delivery guy "Cross dropped" fuel into the wrong tanks. They shut the pumps down immediately and the next day the fuel depot sent someone out and they made a "correction" and told the station all was ok. He then said it obviously wasn't fixed.
I mentioned my car required at least 91 octane (that is what I asked Eric @TT to burn my chip for, since its a driver car)
The district manager then asked me what he could do to make it right. I said refund me the difference in cost for the regular 87 to 93 which is about $9. He said give me your address and I'll send a $20 gift card and we apologize for the inconvenience.
Now you guys with your "new" GNs with a chip burned for 93 or worse yet the stock chip, and boost turned up running with out a scan master how would you know besides having head gasket issues that you got some bad fuel? Listen for the knock? That is pretty late to do anything. So for the millionth time make sure your car has a scan master before you start flooring the pedal.
A gas station isn't going to give you a gift card to cover head gaskets....let along you being able to prove it.
