I was coming back from Mexico after checking out some systems we have over there. I noticed a late model GTP at a gas pump in Mexico filling up. The gas over there is Pemex and I have no idea what grades they have. The gas is now cheaper than ours. The moral of this story is evidently a GTP will run on anything.
BTW - I use VP Racing C10 unleaded at the dragstrip.
