I sort of did both. The first tank (20oz tech to 3/4 gas) was around town, some twisties and to the office. The second tank (20oz tech to 4/4 gas) was a 300 mile out of town trip. I started noticing some real difference towards the end of the second tank.
Gonna change the oil with a valve adj in a couple of weeks.
Maybe i should go for a third dose and she will start to get some boost from the Techron Turbo
