this is a really weak spot on these car's! Unlike the Toyota trucks these cars do not have a powersteering cooler and tear up their fluid. I recomend that you use a good synthetic Dex-III or better. M1,Redline D4,Amsoil,Motul,NEO Dex compatable ATF's all work fine. In fact I got ATF+4 on sale at Walmart and it is GIII so it is almsot synthetic and it is doing well.
