The FRAM filter is fine. If you want better filtration add a by-pass filter.
Using synthetic oil is a matter of choice. No reason to spend $5-7/qt when $1.50/qt is going to do the same thing.
Where are you finding conventional oil for $1.50 a quart? Around here, the average for a quart of conventional oil is around $3-$4 a quart, maybe get it for $2.50 a quart on sale if you buy it by the case (which I do).
