Blue antifreeze is very outdated, it was originally designed to be used in old cast iron blocks, and in the modern alloy blocks, it actually corrodes the insides of the system/block, which can cause problems
There is quite a big difference between the 2 though, alot of people still think you can use blue as they are told wrong, and because it's cheaper, funnily enough even a lot of garages still use blue when they shouldn't
The problems caused by using the wrong coolant are long term though, so you may not get a problem for 6month or it could be 8 month
Just googleit mate theres loads of variances, there's also a green antifreeze too iirc
