At RST Automotive Inc., we help our Fremont customers' cars run as cleanly and efficiently as they possibly can. We provide a range of emissions testing services to ensure that your car is running and driving its best, as well as complying with all local smog regulations. Should a problem arise with any of your vehicle's emission systems, we provide the parts and expertise to get you back on the road. RST Automotive Inc. can replace mufflers/catalytic converters, refill diesel exhaust fluid, and make sure the full range of filters in your vehicle's exhaust system are working perfectly.
Regulators understand that older cars simply can't meet modern emissions standards without extensive modifications. For newer cars however, passing a smog test is a requirement of road legality. Call us at 510-494-8081 to learn more about the emissions requirements for your vehicle.
Emissions testing (also known as smog testing) is a vital part of the maintenance of your vehicle. E-tests provide your mechanic with important information about your car's engine and exhaust system. If important components, like your car's catalytic converter aren't working properly, the car isn't running as it was intended to by the manufacturer. Inefficiency costs you extra money in fuel and does unnecessary harm to the planet. Emissions testing can also affect the value of a vehicle you're trying to sell; while you can still sell a car without a valid e-test certification, you'll get more money for one that has passed the test.
There are several reasons that a car may fail its emissions test. There may be a problem with the vehicle's fuel system adding too much fuel to the air-fuel ratio required for proper combustion within the cylinders of the car's engine. This is known as "running rich" and results in the smell of gasoline from fuel passing through the engine and exhaust system without being fully burnt. Causes of this issue range from faulty fuel injectors to issues with the engine's control computer. There may also be problems with oxygen sensors or the vehicle's ignition system. At RST Automotive Inc., we use a complete set of diagnostic equipment to determine the problem and fix it quickly, explaining every step of the process to you, our valued patron. Call us at 510-494-8081 or send us an email to arrange a health check for your car's emissions system today!

What People Say About Us
I Brought my car in for an oil change. There was a light on the dash panel that I thought was just a reminder to change the oil. Turns out that it was Nissan's version of the check engine light. Roger and his team were able to diagnose the issue and clear the light. Always great service at RST!
I'd have to say after dealing with multiple mechanics in the tri-cities area that, hands down Roger is by far the most honest and professional mechanic I've dealt with to date, I'll be upgrading my 1971 corvette from a Muncie 4 speed to a Tremec 5-speed soon, I'll be contacting Roger again in the near future, to handle this project for me, I can count on his work, and he has the integrity to stand behind his work! Kudos to Roger and the RST staff!!

I brought my recently acquired American Clipper motor home in to have the coolant system flushed and the chassis lube. Roger took care of my needs on my old motor home and I want to continue to get the same service I have come to expect.
Thank you Roger & Jamie for providing excellent service! Our catalytic converter was stolen from our beloved RV. One of my tenants recommended us to them. Our CC was discontinued, but I was able to find a compatible one. Roger ordered it, delivered next day. We brought our RV in, and it was installed, caged. Not only that, we got it smog checked also. All in 1 DAY!! Thank you for helping us out, and providing speedy service. We will definitely will be back again for service on our RV! Thank-you!
I recommend Roger. He is an excellent mechanic and he does specialize in older cars which is what I have so that's helpful for me as well. Prices tend to be on the more expensive side, but with the older car I previously had, he was one of the few who could fix it.
RST has taken care of my truck since it was born. I trust no one else to work on the truck. When they tell me my vehicle is safe and running well, I feel so secure. I am 84 years old and safe and secure is a MUST. 5 stars does not seem enough.
