Oem oil spec recommendations are OW-20 for the b58 engine. This is ok for stock power levels utilizing pump gas. Once ethanol is introduced, oil begins to thin and deteriorate. The thicker 5W-30 is what we *HIGHLY* suggest on e85 cars making sufficient aftermarker power. This is the same oil we run in #1 and #3 worlds fastest supras, both under our teams maintenance and ownership.
