Team Nissan - Service Center

It is very difficult that service department at team Nissan (Oxnard) take your car if you don't have an appointment made in advance... Also, I took my car for oil consumption engine check and they didn' Nissan (Oxnard) take your car if you don't have an appointment made in advance... Also, I took my car for oil consumption engine check and they didn't want to receive it because they said that it needs to be done after 3,000 miles (every 700 miles). However, I received a letter from Nissan NorthAmerica and it says "check your Altima's oil level every 700 miles and top off the oil level to the H indicator on the dip stick if it is below that mark". Also, it mentions that "If you prefer, you may take your Altima to a Nissan dealer and request an oil level check. The dealer will do so, and top off your engine oil if necessary at no cost to you for labor or any oil which might be needed." Anyway, in this letter it doesn't say that you are supposed to do it only after you have reach your first 3,000 miles. I guess they don't have clear the importance or committment to provide high level of product quality and customer satisfaction. More
