Changed the oil, then did six autocross runs on this tank. Overall the car did pretty well, though these Dunlops do not have much stick. The stock suspension has way too much pitch travel. This tank was 93 octane.

Car is showing no codes, and the internet seems to think that the slight puff of a backfire is a characteristic of a small exhaust leak. Can't really hear one, but the car is a bit louder than I think it should be. Note that the backfire is only present when it's 60F+ outside.

Changed plugs, diff oil, tranny oil, shifter turret oil, flushed the coolant, and used fuel system cleaner (both in-tank and direct to fuel rail via compressed air) halfway through this tank. Noticed that after idling with the fuel system cleaner in the rail for about twenty minutes, the fan did not turn on and the car slowly started to overheat (shut it off quickly though). Will need to address this, though even in 110F stop-and-go commuting it has not yet shown any signs of overheating in practice. Car will still make a very slight backfire when shifting while driving it hard at high RPMs, not sure why yet.

Had a flat tire this tank -- bad valve stem, only drove on it for a block so the tire was fine. Temps in the 80s in the morning and 105-108 range in the afternoons, lately.

Changed the oil at about 150 miles into the tank. Used Shell 5w30 dino oil and a $7.50 filter that the scumbags Mazda dealer sold me, which I don't think is an OEM Mazda part. Valve lifter tick is GONE for now and the car is so much more enjoyable. In other news, commute temps have been in the 100-110F range for the past few days, but there have been no overheating problems (with the car, me is another issue).

Changed all four fuel-ups to read 1.5% more miles -- realized that the stock 185/60/14 tire is 1.5% smaller than the 205/50/15 that is on the car.

Quick half-fill-up driving the car home. Purely highway driving... probably represents the car's upper limit.
