I agree with using Full synthetic on High performance engines... In my dads Rusted 80's Chevy farm truck that redlines at 4800 rpm I would say conventional oil does the trick. But on my TL-S constantly running high revvs, I want an oil proven to not breakdown with friction. The molecules of conventional oil are irregular in size and shape... Unlike full synthetic.. but thats my opinion on my car.
