I noticed under the data sheet that 75-85% of it is synthetic base stock...
Is Pennzoil's Synthetic 5W-30 (API SL/GF-3) a Group III or a "true" synthetic engine oil?
I know Quaker STate's Synthetic 5W-30 is based on Group III (hydorgenated something..) API SJ/GF-2
How many miles/months can I leave Pennzoil Synthetic 5W-30 in my Ford 4.6L SOHC V8?
