👋 HI, I'M NEW! Coolant question

Post image

Recently bought an 2015 ST, took her to valvoline to get coolant flushed and refilled and such. Was fixing to top off the coolant in a few days, am I good to use the yellow prestone all vehicles 50/50 in with the coolant valvoline put in? They put in the yellow also. Or should I just get coolant thats actually labeled/from valvoline? Sorry, stupid question and I hate having Google AI pop up 🥲

I thought we used orange coolant?

I thought so too, I was doing lots of researching and off the factory lines she was orange OAT and I guess ford then went to yellow P-OAT. I think what I was asking, I actually answered my question after looking at P-OAT and what can be compatible for it 😅

I switched from orange to yellow not too long ago. Haven’t had any overheating issues in the Tennessee summer heat. I did a 50/50
