“I can’t say enough good things about my experience with Greentech, especially with their mechanic, Mike. I initially thought I needed a costly hybrid battery replacement, but Mike’s honesty and expertise saved me thousands of dollars. Instead of rushing to replace the battery, he thoroughly examined my car, ran tests, and discovered that the issue wasn’t battery-related at all.
Mike found that oil had gotten into the air intake, preventing the car from functioning properly. He showed me the air filter, where there was quite a bit of oil, and explained how this was causing the problem. He didn’t just tell me; he took the time to show me the issue and walk me through it with complete transparency. Mike then went above and beyond by cleaning up the oil, reconnecting the battery, resetting the errors, and taking the car for a test drive to make sure everything was running smoothly.
This level of honesty, integrity, and professionalism is rare to find in the auto repair world. Greentech and Mike didn’t just treat me as a customer; they treated me with respect and care. If you’re looking for a company you can truly trust with your vehicle, I highly recommend Greentech. Thank you, Mike, and the whole Greentech team for your exceptional service!”

“I had a coolant leak that I was trying to fix and the staff really helped me get the parts to fix the broken coolant line. The manager Rapha went out of his way to get tools to help fix the line on the spot. Great attitude and helpful.”
“I’m a newer customer at this location, and I’ve been impressed both times I’ve been in. Today, Connor had a nice vibe in the store, as he was super friendly and engaging music was playing. Thanks for the conversation!
An older gentleman helped me out the first time and educated me on batteries. I’m a big gamer and I can swear by these batteries over the name brands! Thanks so much and see y’all soon once I need a recharge!”
“The customer service was great! My old key fob broke and they took the time and searched to find a replacement for me. I really appreciate the above and beyond service.”
“Nice people, prompt truck unloading. Park on the street, check in, when they open the door, back in off the street. The four wheeler traffic mainly know the drill and we're not impatient.”
“I had a great experience today 10/10/2025 at O'REILLY on McLean and Wing Street. Josh, Roman and Jose took great care of me and my car. They replaced the battery and license plate light bulbs.”
“This is the hidden gem in the Elgin/South Elgin area.The guys working here are the best.They try and help everyone and always seem to have a solution.I am reluctant to post because I dont want them to get to busy.The one in Elgin though sucks ,terrible service and other places in the area dont have enough material and as good of service”
“I would to thank Richard at the O’Reillly parts store in Streameood for all of his help finding a started for my 1958 ford Fairlane Skyliner. It was not easy because the car had Tbird engine and the parts did not Mach up. With his knowledge and clear understanding of older cars he was able to match it up with a photo in the catalog.
While having the transmission replaced I had to replace the torch converter then I had to add a trans cooler then the started went. It seamed like it would never end. I will now order the starter and be back on road. Thanks Richard”
