As we all know, 93 octane isn’t available at every gas station across the country — and even your local filling station doesn’t always receive consistent batches of fuel, So what happens if you get a bad tank of gas or simply can’t get the good stuff when you take a trip? Frequently, aftermarket ECU tunes require a certain octane rating and don’t take into account the fact that you may not always be able to run that same octane rating in your truck.
