D.C. Auto Guide to Using the Correct Fluids in Your Vehicle

Posted November 17, 2019 10:52 AM

Today's D.C. Auto post focuses on using coolant. drive 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 D.C. Auto service advisor will know the proper coolant for your vehicle.

Brake fluid is confusing for some Suwanee drivers. Back when we opened D.C. Auto, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Suwanee 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 D.C. Auto: 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 D.C. Auto 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 D.C. Auto in Suwanee, 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.

Testimonials

  • The owner is so nice and genuinely cares about his customers and their vehicles. My family has brought all of our 4 cars here and past cars and I won't trust anyone else with my cars but them. They won't tell you to come get it until it's up to their own professional standard and you don't get that kind of service other places. They don't haggle you into getting more done than you need and always have great prices. I truly appreciate all the work they have done for my family and any one I have referred to them.

  • Tom and the guys are great! They have helped figure out our car problems when even the dealer couldn't. They never talked down to me, "a woman", and made sure I understood what was what. Highly recommend them to everyone I know.

  • Friendly and prompt with their service. This is important because I have someone ill at home and cannot be away for long.
    reviewicon

  • Tom and the folks at D.C. Auto are simply the best. I've had a good bit of work done on my vehicles over the years and have always been treated well. They're honest, thoroughly explain the problem and charge reasonable prices; everything that you could ask for in a mechanic.

  • Been a DC Auto customer for almost 6 years now. Tom and his crew are top people - never disappointed. Always upfront and honest. Never "pushed" an addon or any sorts like that. One can only smile at a couple of pointed and personal reviews here. Never had "that" problem at DC Auto. Would recommend.

  • Always helpful, always cheerful. Honest estimates, and won't recommend work that isn't needed. If the problem falls outside of their ability, they will tell you right up front. I've taken multiple cars there for years and have never had a problem.

  • I have been going to DC Auto since it first opened. The staff is highly knowledgeable and courteous. Tom is one of the most honest men I know. He is highly ethical and never tries to "up-sell." The work is always superior. After all these years I can't see myself going to any other auto service company.

  • Awesome service at a great price. Always stands behind his work. Tom runs a great shop with great employees and always a smile and a story. Honest no gimmicks what all businesses should be.

  • I have been a customer with DC Auto for close to four years. I have NEVER had an unpleasurable experience. They know who I am when I pull in and do their very best to keep me and my family safe on the road! The crew at DC Auto is outstanding and the customer service is phenomenal.

  • 5 stars...the guys at DC Auto have taken care of our family's cars since they opened. I just brought in my 2005 Honda Pilot with an oil leak. They found the leaky oil pan and replaced it. Not surprising on a 205,000 vehicle - drain plug was getting stripped out. She STill runs like new because I keep it maintained (at DC Auto). Fact is they do great work, they're honest and prices are good. No stupid high pressure. I trust them. Highly recommend.

  • Fantastic service shop my husband and I (as well as several friends we recommended them to) have used for years. I know "honesty" isn't often a word associated with car mechanics but Tom and Rob have always shot us straight about our vehicles, and I know it to be true because several times, their advice to us has actually cost them a repair job (and saved us money). They typically get us scheduled same day or maybe the next, and the turnaround time is speedy. For hometown feel, honest opinions about your car, great service techs and reasonable prices, use DC Auto.

  • DC Auto is the what every car repair shop should be. These guys are great! They easily find what is wrong and fix it in a timely manner. The other reason I will refer anyone here is because their pricing is very reasonable. This place is better than others and WILL NOT overcharge you for every little and last thing. Go to this place for any car maintenance big or small. Tom and Robert in particular are who I would suggest, although everyone on staff is very good.

  • 10/10. Would recommend. Personable and knowledgeable mechanics that don't try to rip you off. Great quality work for reasonable pricing.
