With the 5.8 pan no deeper than the 5.4 oil pan, the 5.4 oil pump pickup was reused, saving money. The 5.8 pan employs a simple stamped-metal baffle for anti-slosh protection in the sump, and the new pan has no trouble handling road racing acrobatics says SVT. Any increase in engine rigidity or sound suppression provided by the casting is unintentional say the engineers; the only reason for the cast construction was to achieve the necessary shape. SVT also clarified the 5.8's increased oil capacity does not increase its oil-change interval. The 5W-50 synthetic should be changed every 5,000 miles under severe duty or track conditions.
