Letís take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.
It was common in those days to use a lighter weight oil in the winter when itís cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldnít thin out too much in the summer heat and vaporize in the engine.
Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.
So new weights of oil have been introduced to meet the engineering specifications of these newer engines.
Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. Itís certainly in the ownerís manual. Of course, your Chicago Illinois auto service center can look it up for you.
Itís more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.
Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.
In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.
So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasnít formulated to protect your plastic cooling system parts, they could become corroded and fail. And if youíre using the wrong coolant, your cooling system wonít be covered under warrantee. So itís important to use the right coolant and to not mix different types.
Your ownerís manual or your Chicago Illinois service advisor at Triangle Auto Service can make sure youíre using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. Thatís OK for an emergency top off, but following your manufacturerís recommendation for your Minivan or other auto type is always a safe bet.
In the area of brake fluid, there are a couple of new formulations. Itís important to remember that the new ones arenít better than the old ones. Theyíre just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.
There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.
Theyíre fine to use as long as theyíre a variant of the proper fluid. In other words you can use a high mileage engine oil as long as itís also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as itís the right type for your transmission.,,
