I put the new Mobil 1 10w-30 in my 2005 Accord. Runs great with it. It's good to see a large oil company like ExxonMobil push for extended drains, much like Amsoil has for years. In Europe, the average person changes their oil every 10,000 miles. Only here in the U.S. where quick lube places have an impact along with stringent EPA regulations, do we still change the oil at 3-5k mile intervals. With the 2.4L, you can technically go 10,000 on the regular stuff, but I'd feel more comfortable with a high end PAO/Ester synthetic like M1/Amsoil than a regular dino oil. Cleaner engine and less deposits. Well worth it. Any questions about oil, go to www.bobistheoilguy.com

Mobil 1 has always been tested for 25,000 mile drains and in fact recommended that when it first came out. However, the automakers weren't too happy with that so they dropped it.
