I had to flush and clean my cooling system in the Jetta.

I have alot of green and shell rotella truck red coolant from my buddy

right now blue devil flush is in the system with distilled water, is it fine to use either of these coolants?

I will be thoroughly flushing the system with distilled water later tomorrow making sure no blue devil is left.

I dont have enough g12 and wont pay for it if i dont have to.
 
Why did it need flushing?
neglected cooling system and blocked heater core, literally caked in rust, its almost all gone now after months of thermocure and now finally blue devil.
 
Just buy some Zerex G-40 concentrate and add it to the radiator after your done flushing. Also do a reverse flush on your heater core.
 
OUt of the two the Rotella ELC would be the better choice for a 13 Jetta, but if it were my car i'd use the new G12 Evo coolant VW is using now.

Rotella ELC is basically hust a OAT coolant just like G12 for example would be, although your 13 Jetta would have had G13 from the factory which is basically just G12 with Silicates.

Zerex G40 would work just fine too.
