What's the 2004 infiniti g35 coupe oil type?

The 2004 INFINITI G35 uses SAE 5W-30 oil in the engine. INFINITI recommends that You use full synthetic oil whenever You need to change it for the best protection. There are two main types of oil that are on the market these days, conventional and synthetic. Conventional is produced with petroleum and has been around for a long time. Synthetic is newer and engineered in a lab to give You better wear protection and longer life. That means synthetic oil only needs to be changed every 7,500 miles compared to 3,500 to 5,000 with conventional. You should make sure to check Your oil at least once a month to make sure that it is full and free from any debris.
