I had what looked like a cup of oil on the garage floor after I pulled out. The oil level was still full and I had no warning lights so I drove to the KIA dealership. A couple hours later they called and said the oil filter was leaking. I have 5400 miles and my only oil change done at Big O Tires used an after market oil filter. The service department manager said the KIA oil filter has a slightly different fitting than the after market ones. He said the V-6 puts out alot of pressure and the after market filters not sitting right comes loose. Does this sound right?
