Today's Tuffy Tire & Auto Service Oswego post focuses on using coolant. 
If you pour in the wrong kind, it won't protect the cooling system and may even void the warranty. Check your vehicle owner's manual. Of course, your Tuffy Tire & Auto Service Oswego service advisor will know the proper coolant for your vehicle.
Brake fluid is confusing for some Oswego drivers. Back when we opened Tuffy Tire & Auto Service Oswego, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Oswego residents mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That's not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is designed for your vehicle.
Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at Tuffy Tire & Auto Service Oswego: friction modified or not. With the tremendous engineering advances in vehicle automatic transmissions, there have been several new types of fluids developed to protect and lubricate them.
Nowhere are the advances in automotive fluids more evident to Tuffy Tire & Auto Service Oswego professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today's high-tech vehicle engine design. Modern engines have more parts and much tighter tolerances.
That's where the new grades of engine oil come in. They have to be formulated to lubricate, protect and clean all of those vehicle engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.
At Tuffy Tire & Auto Service Oswego in Oswego, we believe that in some ways modern automotive fluids are just as impressive as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, make sure you always use the proper fluid if you are topping off at home.

The price of gas in Illinois has got people in Oswego talking. It seems that Oswego folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel eco... More

Any Oswego driver who understands preventive maintenance knows that if it ain't broke, don't fix it is bad auto advice. Replacing a part before it breaks is much less costly for Oswego residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is th... More

You're heading down the road and you notice your vehicle is sputtering, like it's running out of gas. But the gauge show's it's still got a quarter of a tank. So what gives? It could be that your fuel pump is failing, meaning your engine is not getting enough gas to run properly. While fuel pu... More
