2007 Chevy HHR with a 4 cylinder 2.2L ecotec engine Calls for 5w-30 GM6049 (change by the oil life monitor) NC Easy and slow, with an occasional aggressive pull out at intersections mostly a 9mi trip/12minutes... and the once a month trip of 80 highway miles no known problems I'd like to use a synthetic/store bought/as run it as long as i possibly can
1. What kind of vehicle you have 2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well 3. Where you live 4. How you drive (easy? hard? fast? slow?) 5. What your daily drive is like (short trips? long trips? city? highway?) 6. Whether your car has any known problems If you have any preferences -- synthetic vs. conventional, store-bought vs. ordered online, how long you'd like to go between oil changes, etc. -- or any other info you think might be important, let us know that as well.
