Antifreeze Prestone or OEM BMW

my buddy put the Preston stuff in his v6 cause you can mix with all colors and hes been fine for 6 months now not an issue.

I topped mine off with prestone platinum. Meets Ford spec and has been fine

last time I needed to top off my coolant, I used Prestone and been fine for last 15k miles

I only ever use Prestone universal coolant, from my newer car to my 1962 bulldozer.

I used genuine bmw coolant as the price was around the same.

I just use prestone, it's green coolant. It's universal for all fuel types and coolant systems. I have never had any issues in the many years I have been using it.

BMW coolant is down right awesome stuff.

My mechanic just switched my antifreeze to “Prestone yellow”. He said it’s for cars with high mileage (150k and higher) he said it’s softer on our old hoses and such! Car is running great.

that prestone that says it can be mixed with any type of coolant can do just that. You can mix it with pretty much anything and it won't cause a problem. The industry is well aware that if you mix certain types of coolants, you will end up with a sludge so they make this prestone stuff too be compatible with everything. Now, just because it's compatible, doesn't mean it will last as long as some of the other coolants when they are 100% the exact coolant.

I’ve done it with my fiesta that had a leaking thermal housing I think I ended up topping it up so much by the end it was almost all Prestone wouldn’t personally do it on a car I care about though
