I would have to say that 5w20 on the 8's is my choice, esspecially on the 09 modles, the OMP and filter system is completely redisigned to reduce carbon build up and prevent flooding issues. the omp on the 09s continue pumping as long as the engine is still turning key off engine off. they have also included 2 additional oil injestors, all in jectors are PCM controlled with 2 OMPs.not saying 5w20 is the only or best choice, but typically the engines i see with lower than normal compression have been flooded and incorrectly or harshly deflooded or never were allowed sufficient warm up time before ragging the hell out of it....the bearings in the pictures before deffinatley looked like corrosion or starvation...maybe the changed it every 3k but only after a year went by
