Oil? pffffff

My engine is run on Tigers blood and Chuck Norris sweat.

In all seriousness, Kracka is spot on in his analysis, spec the oil based on bearing tolerances not horsepower. What brand of oil is used, is mostly personal preference, each oil brand specs out different additives they use, some additives are better over a short term life others additives last longer over the long haul but are not as effective.. pick your poison.
