1. What kind of vehicle you have 2008 Silverado, 5.3 liter AFM flex fuel
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. 5W30
3. Where you live, South Carolina
4. How you drive (easy? hard? fast? slow?) easy
5. What your daily drive is like (short trips? long trips? city? highway?) short trips, less than 15 miles twice a day, city
6. Whether your car has any known problems. This engine is known for lifters leaking by after sitting for a few hours, every morning for me, and ticking for a few seconds or longer after initial start up. Engine class is known for oil usage if lifters goes bad.
Mine has done this since I bought it with 92,000 miles. First oil change I used Mobil 1 5w30 DEXOS labeled, and the engine didnt tick till after 4000 miles. No oil usage and plug were fine. I also used AC delco filter with anti drain back filter.
Second and third oil changed I used Pennzoil Full synthetic platinum, or whatever their best stuff is, and the engine started ticking at less than 2000 miles upon start up.
Fourth oil change back to Mobil 1. Currently at 111000 miles.
So, my question is, what makes the oil within Mobil one bottle seem to maintain its integrity longer within my specific engine? Or is their an oil that actually can get into lifters quicker or stay in lifters longer due to the oils recipe. I would like to have oil last longer than 4 or 5 thousand miles in the engine. But if I have to change early, am I wasting money on synthetic.
