I took my vehicle (2012 Chrysler 200 Touring) into this local grease monkey on 6/24/2019; a Monday for a simple oil change "4.6Qt 5W20 Conventional" (waited this long to do a review to see if they'd correct the problem *they didn't*)...I got my car back in about 45 minutes; perfect. I went home, car sat for the night the next morning I go to head into work and my engine is "ticking" (NOTE: It did NOT have a tick when I took it into the shop the day before; continue reading) I called up grease monkey that day and requested the manager to call me as he was busy; didn't hear from him. I called again Wednesday (2 days after the service) I talked to the GM and he told me to bring it by. After he checked it out; they proceeded to drain the new oil, and replaced 3.6Qt with 10w30 and 1Qt of Oil Additive. He said drive it around IF it is still ticking on Saturday 6/29/19 to bring it back, So I did. Once he checked it Saturday, he told me to keep driving it and he would talk to the owner and see if we could come to an arrangement on either getting it fixed, or something. As this is my ONLY daily driven car I proceeded to drive it to and from work, and to pickup/drop off my son from school.
The GM went on vacation the following week and was unavailable. So July 8th, 2019 comes around and I'm still driving it, it's still consistently ticking, not getting any worse. The GM gets back tells me to get an appointment with another shop to diagnose the issue. I called around and earliest I could get it in was July 12th. Low and behold with my 5 year old son in the backseat on Powhite South at 5pm going about 55mph my engine makes a loud *Clunk*, I hear a noise like marbles are in my engine and then engine shuts off; while going 55mph, I merge over to the shoudler/slow lane and stop; being I'm less than a mile from my house I attempt to start it it starts but sounds horrible, and has little power. I get it to my house and attempt to check it out; not leaking any fluids or anything......
Needless to say I reach out to Grease Monkey and explain the issue to them, Of course they deny everything.
Finally on 8/27 I get the e-mail to the owner Mr. and Mrs. Koval, asking them if they received my documents of me having to buy a replacement engine and having that installed. They reply back saying they received the information and what I would like them to do. I explained that I'd appreciate some sort of compensation for the ~$2000 I had to put into my car after visiting this establishment, they replied with can you explain with what failure happened internally to my engine; I told them to call the shop that had replaced my engine and told me that cheaply produced oil usually caused this type of failure and gave him the number to the shop.
I didn't get a response for almost A MONTH so I attempted to reach out again, letting them know I will be writing a review on every platform available regarding their shop. His response was "Legal Action" His Quoted Response is as follows: "Of in 40 years of automotive repairs (as well as business) as well my asi certifactions,nerver heard ever heard using a thicker oil in a 20 year old car as well as having close 200,000 miles would cause engine failure , so if your mechanic is indicating that please bring him to court with you."
(Mind you I have a 2012 Chrysler 200 *at the time* having 145,404 Miles upon servicing; So a 7 Year old car, with close to 150,000 Miles)
After I got that I googled "will thicker oil hurt my car" and the first thing that pops up is an AmSoil* link stating "*Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don't transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.*"
My last e-mail on Sept 26, 2019 was never responded to to this day 2/28/2020.
Needless to say, Myself and family and Friends no longer use them.
