2007 Kia rondo 2.4 ltr. Automatic, 2000 Tacoma & 1969 VW bug.
I know I said final report but just one more.......3,000+ miles and within 1/8” from full on level ground. A lot better than the 3/4 quart per 3,000 miles I was experiencing with the non synthetic 5w20.Final report......2,000+ mostly highway miles in summer heat . ZERO oil usage. Still at full mark on level ground.
...........I’ll be sticking to 5w20 synthetic high mileage from now on.
