Like 50/50....Dislike Prestone
Out of curiosity, I went to the Prestone website to look for a Product Data sheet. none available.
I haven't put Prestone in any of my cars for a very long time. Thought I would give them another chance, since they have done a lot of reformulation in recent years. But if they won't tell me what base formulation (OAT, HOAT, PHOAT, etc.), I won't give them a second look.
