Shoot as soon as I turn my key the
oil pressure is there, within 1 revolustion of the engine. From my miniscule understanding of
oil, synthetics thin easier than mineral base when cold. During startup their viscosity is lower, which flows easier to engine parts. Synthetics do not need the same amount of polymers to acheive the same viscosity index, when you hammer your engine and your piston skirt is flying around I would rather have
oil between the piston and cylinder than polymers.
