Shell 93 Octane. I am certain I pressed the 87 button for $3.199/gallon. 3/4 into the fill-up I noticed the 93 premium price above that button was displayed. I don't mind filling up my turbo car with premium, if I actually requested it.

Shell 87 Octane. Topped up tank at another gas station because at last refueling the pump stopped early. For these two refuielings I put in 12.074 gallons. Less than the 12.7 gallon tank capacity.

Shell 87 octane. Ran this tank until gas gauge said 0 miles remaining. Ultragauge Blue said 11.7 gallons used (from 12.7 gallon tank). Pump stopped early. Saw gas gauge at 7/8 tank after refueling. This is a partial tank.

Shell 87 octane. No noticeable difference in performance or economy with Shell 93 octane last tank. Saving the $8-$9 per tank to stick with regular as the car happily runs on the recommended 87.

Shell 93 octane at this fill-up at less than 1/4 tank, 2 city miles from work this morning. Won't know the effect of high-octane until it gets from the tank, through the fuel line, to engine. Cost me about $8.50 more than 87 regular would have. I don't plan to regularly fill with premium, as well, the cost is a premium.

Admiral 87 octane. More city vs freeway driving this tank has decreased MPG. First 1/3 of tank was city-only, low 20's MPG. MPG increased as the freeway miles clicked on. Ran tank to "empty", 0 miles remaining. Put 11.259 gallons into 12.7 gallon tank. Could have tried adding another 1.5 gallons, but I am in the habit of ending fill-up when the pump shuts off.

Shell 87 octane. Filled up while tank was nearly empty. 2% per MyMazda app. There must be nearly 2 gallons in reserve in the 12.7-gallon tank at such a low fuel gauge display.
