just finished the rebuild on misses wrx sti my95 classic.
ive put 10w 40w in just to start up and run up to temp etc. i'm going to to drop this oil but wondered whats best to use to run engine in?
is a semi synthetic 10w 40 suitable? i plan on changing the oil again at 200 miles then 500 then 1000 and engine should be ok?
thanks

any running in oil will be fine, there's no need to pay over the top prices for this oil as it'll be getting changed after a few miles anyway, just make sure it's mineral based. Most motor factors i've been to have stocked running in oil on the shelf.
