Re: Are synthetic oils and lubricants any quicker
Quite a few years ago, I read an article in a MuscleCar magazine in which they did a back to back comparison of regular and synthetic lubes in a '69 Hemi Charger with an A-833 4-speed and a Dana 60. IIRC the total difference between dinosaur oils and synthetics in engine/trans and axle was 3 tenths. Car went from 13.00 to 12.70 doing nothing but changing to synthetic lubes.
