New oils with less ZDDP.

here is another one.....kendalls GT-1 hi performance 20 -50... carries the api of SJ the 10 -30 and 10-40 carry the api of SM ...the SM is for the newer cars. they also make a synthetic for the guys that like them.... .... bottom line ...look for the api rating SJ..... thats the one we need.... and remember ...fifty cent oil is made for fifty cent engines.......
