We would like to give you an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday – and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace. The do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many CO car owners rely on the advice of their service consultant to not only get the correct family of fluids, but to suggest the formulation that is best for their car and the way they drive. Let’s start with engine oil. If you have been paying attention, you will have noticed a number of new oil weights on the scene in the last several years.

That’s not surprising. Even though power steering is standard on every vehicle, most people in Boulder aren’t aware that it needs periodic service.
