  1. So, I've had this truck about 15 months. I bought it used from Carmax and ran 87 octane for the first year or so. I noticed that I got a good bit of engine pinging. It's would get worse under load or in hot weather. And during that year I always felt like the truck was a bit of a dog. In January, I'd had enough and bumped up to 91 octane for a couple months. It got much better but didn't quite go away. About 3 or 4 tanks ago, I switched to 93 octane (premium, in my area) and I don't think I've heard it ping once. The mileage hasn't changed (unsurprisingly), but the truck just feels "peppy." The throttle response is massively improved and it's a much better driving vehicle. I think the best way I can describe it is that it's no longer lazy. I mean, it's not a sports car, but it no longer needs a few seconds to get it to accelerate. I know the instant response to that is "it's all in your head" but my wife who has no idea (read: doesn't care) what's been going on commented the other day that I haven't complained about the truck's performance lately. I'm not excited about having to feed this beast premium, but if I don't I'm afraid it's going to tear itself up. Also, I haven't changed gas stations through this time and the ones I use are busy, top-tier locations so I'm not thinking the quality of the gas is involved. I'm thinking the truck was tuned by the previous owner. I'm going to ask about that at my next service visit, but I don't expect they'll tell me anything. Is there a way I can verify if the truck is on the stock tune? Also, has anyone else had a similar experience?
