Valvoline Restore and Protect 5W-30!
An oil that has been tested here on this site, with a high percentage of skeptical users that have seen great results, and non-user that have heard from others that it is just not marketing, it really works on a very very high percentage of cars/trucks. I still think Valvoline should of pushed the 4 oil change suggestion to 6, for some very problematic cars like Hyundai/Kia's that seem to need more time to see results.
Why wouldn't you want to use an oil that actually does something different then almost any other oil you would choose. All for $30 for a 5 qt jug.
