If any of you are running a motor that's not too modified, I'd like to introduce you to the Signature Series line of motor oil. It's a top of the line synthetic motor oil that protects your motor with a combination of base stocks and additive package to provide you with the most advanced motor oil available. In addition to providing a high level of protection, it is also an extended drain motor oil in that it is guaranteed for up to 25,000 miles in some applications(15k for most sport compacts) If you're driving your car at least 10,000 miles a year and you change your oil every 3,000 miles, this will save you money as well.
