Enhance Your Vehicle's Performance

We Keep Your Car At Peak Performance

Maintaining optimal engine performance is essential for your vehicle’s health and efficiency. At Zarn Automotive, we offer Engine Performance Restoration (EPR) services to address common engine issues and restore your vehicle’s power and fuel economy. Your engine's performance can suffer due to various issues, with one prevalent problem being low tension in the piston rings. When piston rings lose tension, it can lead to oil contamination, oxidation, and a loss of pressure in the combustion chamber. These issues result in reduced engine performance, more frequent oil changes, and decreased fuel efficiency.

Our EPR service tackles these problems by eliminating buildup on the piston rings, which prevents oil contamination and oxidation and restores proper ring tension. This service can significantly improve your engine's functionality and overall performance.

In the last 8 months I've used Zarn twice-- most recently to fix an electrical issue with sensors and previously to diagnose and eventually replace my transmission. Their customer service is stellar. I was in a time crunch this past weekend needing to know if my car was drivable out of town for a soccer tournament. They got me in quickly to diagnose the problem and managed to get my car repaired and ready to drive for the weekend. I know that isn't possible all the time but it really helped me out. Zarn communicates well and timely. Their prices are reasonable. Mostly, they are honest and not trying to upsell on anything. They are patient and take time to answer all my questions about car stuff I don't understand. This is why I'm a repeat customer.

I recently took my wife’s 2017 Mercedes GLS450 to Zarn Automotive, and while car issues are never fun - especially right before the holidays... the team there made the experience as smooth as possible. They were honest, transparent, and provided a clear plan for the necessary repairs. They fixed the coolant system issues and installed a new drive belt. Micah and Neil were incredibly professional and straightforward about everything that needed attention. We’ll be scheduling some follow‑up work, but I truly appreciate their honesty, hard work, and the fact that they got the car back to us before Christmas Day. Highly recommend this team.

First time using Zarn, for transmission service on my Alfa Romeo Guilia. Called & spoke with Micah, who texted me a detailed estimate. Very friendly, courteous & professional. Seemed knowledgeable, got me in and out in a reasonable time, price matched the estimate. They do walk-in/same day on routine service. Will definitely be back & would recommend

I brought in my Infinity for a 2nd opinion on a repair that our dealership told us we needed. ZARN went above and beyond our expectations in figuring out what the exact problem was and what needed to be done to fix it! There inspection was much more thorough than the dealership and they were amazing at explaining to us exactly what was wrong and how that would effect my car in the long run!! All the employees there were knowledgeable about cars and would do anything to help us out. I can’t say enough about ZARN…..we will definitely use them now instead of the pricey dealership service departments!!
