"your car loves you" meaning you feel a difference? is there a noticeable improvement over OEM juice? Give some details.

Back in 83 or 84, I forget exactly which right now, I bought two new bottom end Hondas with solid lifter valve trains that, because of component wear, required periodic adjustment . The specs on the valves were .005 + or - .002. At the first oil change I went in and ever so precisely set the valves at .005 and put synthetic in one and petroleum base in the other. I then checked the valves at each synthetic oil change of 10,000 miles and every other petroleum based oil change of 5,000 miles. The petroleum based reached or exceeded .007 at 65,000 and the synthetic reached it at 155,000. I've run synthetics at the first oil change in every new car since, I'd guess that would be ten or twelve including three Toyotas, and none of them have been oil burners and I have ran all of them more than 250,000 miles before trading.
