I HAVE A 98 SC2 IT HAS OVER 200K UP UNTIL A COUPLE OF WEEKS AGO WHEN MY SON STARTED DRIVING IT AND DID NOT CHECK THE OIL. ON HIS WAY TO WORK IT WENT BOOOOOM!!!!!!!!!!!! #3 ROD THROUGH THE SIDE OF THE BLOCK. WHAT I NEED TO KNOW IS WHAT YEARS THAT ENGINE BLOCK WAS USED, AND CAN I USE AN OLDER BLOCK? I KEEP FINDING OLD CARS IN THE SALVAGE YARD, NOTHING AS NEW AS MINE.

Go here and read! Tells you more than you ever wanted to know about Saturn engine interchange stuff.

When you put the motor back to gether rather than using the oil viscosity recomennded by Saturn, a light wieight oil the favors fuel economy rather than engine reliability, select a weight based on Viscosity vs Temperature charts.

A 10 W 30 is a good year around oil for many climates. I live in the S.W. and 20 W 50 is good for zero to 100+ degrees which suites my conditions. The engines are now getting long in tooth and high mileage and probably should have used a heavier weight oil in the first place to protect against engine wear and the reported high use of oil consumption that seems to prevail now for many.

UnclJohn has the right message here. My personal selection for the three Saturns have is 10 W 40 year around (I'm in the southeast). Also, for those that have newer cars that tell you how much "oil life" is left, my personal choice is to change it out at the 40% point regardless of the mileage/time since the previous service ....
