I find the type of engine oil used and OCI is like a baby and diaper brand you use to wrap him. Use a good baby diaper and can stretch your baby feel good level duration before diaper gets loaded with pee and feel good level drops... Cheaper ones shorter interval before baby whines. If you keep stretching either good or bad diaper till feel good level goes down, end result will be the same - no diff la. If you keep the good diaper change interval the same as the cheaper ones, baby feels more comfortable and happy all day long! Treat your car engine like a baby! The extra margin offered by a semi or syn gives you some additional time in case you are too busy but don't always abuse-la... Even if your car engine internals looks sparkling clean inside that's just the looks as you did not actually measure the wear and tear inside. My 2 cents.
