the valvoline restore and protect is same chemistry just not as aggressive as the old stuff.. instead of one oil change they recommend 4 with a bad gunked up engine. it cleans a little all the time to prevent clogging up oil filter.. whne i put some in my 188K mile hyundai that looked good inside i keep old filter on for the first 300 miles then switched to new one. figured the first miles would get the most out and then pop in new filter.. the dipstick is much cleaner for sure.
