I came to get my oil changed with an appointment today because I saw an Ad online for a discount. I preferred to use my own type of oil because my engine was built by my mechanic before moved here from california. The young guy working service desk was rude and refused to use my oil because his computer told him it took something else. I tried to explain that the thicker oil I use has been in my engine for years. The employee cut me off and was rude explaining to me. I wont get my car serviced here for anything else ever again as Ive been loyal for a few years in california. The cashier inside the store was great and polite.
