How important is it to change the oil every 3 months? I put mobil 1 synthtic in it around novemeber but it has only been driven like 2k miles. It still looks brand new.
According to Amsoil, although not Mobil 1, with synthetics you can go longer than 3 months or 3K miles between oil changes. Go to their website and check it out. As long as it is not black and smelly, you should be fine though. Synthetic is a good choice. I'd used synthetic for more than 1/2 the life of my motor before rebuilding it - I put over 125K on the motor within 3 years. When I disassemble the engine it was clean, even so clean that the machine shop thought that I'd already cleaned the engine when I took it to them for machine work.
the 3 month thing is just mainly for regular oil as the heat cycles and stress start breaking the oil down.....synthetics are not affected by this as much therefore lasting longer
