So is anyone here with a 2010 4.6 Tundra abiding by the 10k mile oil change interval? I just hit 5k miles and don't think i could wait another 5k to change (even though i'm not hauling or using truck in extreme conditions). I know that synthetic oil is supposed to last longer but 10k miles seems so long. One of my buddies says he will change the oil at 10k miles but the oil filter every 5k miles....i think i will compromise ang change it at 7k miles. Any thoughts from owners???
