I will try to wait for 2 consecutive sunny days to pick up my new IS300. Preferably a Friday and a Saturday. On the first day, I will do a closer inspection on the car on the sun before the PDI.
On the next day, I will wash the car, wax it with Zymol, apply the rain disperser like the Rain-X, apply leather conditioner, carpet protector and call it a day.
Then I will drive the car as much as I can to crank up the milege until it breaks in. Then I will bring the car for a natural oil change.
4000km for another oil change, then 6000km for the last natural oil change. For 12000km and onwards, I will use synthetic oil and also apply Slick 50 to the engine...
