How Often Should I Change My Oil?
Since synthetic oil retains more of their original performance characteristics over time when compared to conventional oil, some manufacturers, like AMSOIL and Mobil 1, suggest extended service intervals. Mobil 1 currently offers a 15,000 miles oil while AMSOIL offers oils with 25,000 mile service intervals. Of course, both companies have performed testing on their products to ensure that the desired level of protection is maintained throughout the service period. However, it's a good idea to still perform oil filter changes at the regular service intervals. Some manufacturers also suggest upgrading your engine's oil filtering system if you are going to run the same oil for an extended period.
