My daughter took her 2021 Mazda into Meineke in Charlotte NC for an oil change because she was away from home for several months. They charged $79 which came to $93 after tax and "shop supplies' expense. I called them to ask what synthetic they used (because I like to stay with the same oil for at least 2 OCI's). The guy told me we use Citgo synthetic "inorder to save our customers money". I have no problem with Citgo synthetic but I was a bit surprised that they used a $2 Primeguard oil filter (Chinese made) on a synthetic oil change. I'm not complaining but $93 isn't exactly cheap....I think my daughter now appreciates dad doing her oil changes for free....and using Mobil1, PP, QS, Castrol etc...
