Oil Changes For High-Performance Cars

At Kar Tech in Saint Charles we know there's nothing more important for a high-performance automobile than a regular oil change. Whether you drive a new BMW or classic Chevy muscle car your engine exerts intense power, heat, and compression. You don't need just any oil change, you need an oil change made for high-performance vehicles.

At Kar Tech we install oil filters that range from organic fiber to metallic depending on your driving style and application. Depending on your utilization, we will add conventional, blended, and fully synthetic oil needed for daily driving, or fully synthetic formulas specially balanced for friction reduction when racing.

Maximize performance and horsepower and minimize the damaging effects of heat and friction with a regular oil change at Kar Tech. Call 636-441-8121 to set up an appointment or stop by our auto repair shop in Saint Charles located at 4600 Central School Rd.

Always good work and fair prices. I have a Tahoe that I purchased new that now has 340,000 miles, and a bunch of Jeeps with 240,000 miles apiece, I credit Kar Tech for giving me the ability to keep my autos on the road so long.

I have used Kar Tech for the last 10 years with 3 different vehicles. I feel so safe and comfortable taking my car to them. I get honest feedback. The prices are great and the service is awesome. They always get me in quick and are great at explaining everything to me. I appreciate having them as my go-to more than they know. Thank you!
