The automotive professionals at Signal Garage Auto Care would like to give St. Paul drivers 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 Minneapolis 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 MN car owners rely on the advice of their caring Signal Garage Auto Care service specialist to not only get the correct family of fluids, but to suggest the formulation that is best for their car and their driving habits.

Let’s start with engine oil. Mendota Heights drivers who have been paying attention, will have noticed a number of new oil weights on the MN scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The auto manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your St. Paul service center will know what weight your manufacturer recommends – and it’s important to follow those recommendations. Your service specialist at Signal Garage Auto Care can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that auto manufacturers are using to build the cooling system. Using the wrong type of coolant can actually void your warranty, so you want to get that right.

Transmission fluid is becoming specialized as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your St. Paul house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids you need will grow. And, some of the formulations will cost a little more. Fortunately, Signal Garage Auto Care will continue to update their training to keep pace with technology so that you’ll get the right fluids your car needs. It’s all part of the commitment we make to your driving peace of mind.
