Synthetic transmission oil
Introduction
The idea here is that synthetic oil has less friction leading to less energy being absorbed as heat into the oil. It can also help your car start faster in cold weather and warm up faster. Also increases parts life.
This mod is most effective for vehicles in cold climates, since the viscosity of conventional lubricants increases as ambient temperature drops.

Instructions for mod
At your regular transmission oil change, put the proper synthetic oil in.

| Weather Spotter | Toyota Matrix, 2006 | $10 | 0 | About 1%. tank to tank (no ABA testing) In the winter it helped my car start & warm up about 15% faster. |
The national research council found that Low Viscosity Lubricants (synthetics act like lower viscosity) could get a .5% MPG gain for $6 to implement. This gain covers both engine and transmission oil.
