an italian tune up on the way to some delicious eating place up north or down south, is tastier than going to the talyer.
I always miss those freshly cooked Chopsuey in Baguio, and the "kakanin's" of the south like the Espasol, Buko pie and the like. Enjoying the food, the ride and the Italian Tune-up! Sorry off topic!
A 70/30 water to coolant mix may improve cooling efficiency but that's at the cost of less...
Coolant...
