Replaced transmission fluid with Valvoline ATF+4, drained just over 2 qt and put in about 2.5 qt, level was halfway up crosshatch and is now almost 7/8. Notchyness and trouble shifting in to 1st fixed.
Removed heated fuel (which didn't heat much), since it was in the way and useless.
5/14/13 - 210000mi - Added 3qt of 0W-30 oil, was 3.3qt low. Oil light was coming on during hard braking.
7/15/13 - 213275mi -Changed to 5W-30 Mobil 5000 dino to see if this would not disappear as quickly, and FRAM Extended guard.
11/29/13 - 219518mi - Changed oil to 0W-30 Mobil 1 and FRAM Extended for winter.
Current Mods: Goodyear Assurance tires at 50psi.
Disabled DRL.
HAI.
Fuel preheater (doesn't heat much).
Gapped around front, hood and rear hatch.
Air deflectors in front of rear and front tires.
Drip edging side skirts.
Lawn edging airdam/grill block, only about an inch longer than using a nose bra but I think pushes air to sides better instead of under the car. Also duct taped around headlights and most of grill so only small openning and smoother air flow.
