SAW THIS AT O'RILEYS

Personal opinion. That is too heavy for a drag car. A circle track or road course car, might be able to use it. Their oil builds a lot more temperature. I have always run 10w-30 in every thing I own, and have never had an oil related failure. Proved a point to a friend, some years ago. Put 3 passes on my "stock eliminator" car using 10-30. Change the oil and filter, at the track, to straight 30, and did 3 passes. Then changed back to 10-30, and 3 more passes. Averaged the et of each set of runs. The 10-30 passes averaged .150 quicker in the 1/4 mile.
PA: same brand of oil.
