5-30? Seriously, dude?
Your 95 will actually take about 7.5 to 8 qts of oil. 10-40 is probably a much better choice. Synthetic oil is about $6 a qt, bulk dino oil is about $.99 a qt. Most places that advertise cheap oil changes, say in the fine print, "up to 4 or 5 qts of oil, filter extra...) They probably own the car wash so it cost them nothing...
No matter where you go, there you are.
