most any non detergent single weight oil will work-MAKE SURE THE OIL HAS LOTS OF ZINC OR USE A ZINC ADDITIVE ---one easy pass to get everything seated--2nd pass a little more aggressive to about the 1/8 --3rd pass real aggressive to the 1000 foot --then after every pass you have checked for leaks ,valve lash , jetting, timing etc. and everything appears to be OK and the car goes straight and shifts & stops etc. change the oil put in a new filter etc.----LET ER RIP---FED 387
