That would be my concern also, considering it is designed for veteran and vintage vehicles and one of the 'modern' ones I listed earlier is not suitable for aluminium engines after 1985, maybe we confuse ourselves with 'science'??So mixing RMI 25 additive with glycol coolant should then produce ultimate cooling medium ? Or am I confusing these things?
Just to throw a spanner in to this discussion what about this ==>
Super Soluble Oil Radiator Coolant
My concern would be that rubber seals designed for glycol coolants don't usually play well with petroleum products. Otherwise it sound as fantastic alternative.
Same concern here. I had read about the use of soluble oil for old tractor engines and stationary engines. The oil itself is much the same as machine shop soluble cutting oil. But the possible problems with rubber and plastic components would concern me. Mono-ethylene glycol - or MEG is effectively a very soluble oil anyway, miscible in water and alcohol. In the petroleum industry we used massive quantities of the stuff to extract water droplets from crude oil and separate condensate water from raw gas. The MEG is pumped into the raw oil gas mix and then extracted and dried for continual recycling. I am sure if there was a better and reasonably priced liquid that is both anti freeze and raises the boiling point then car manufacturers would be using it.That would be my concern also, considering it is designed for veteran and vintage vehicles and one of the 'modern' ones I listed earlier is not suitable for aluminium engines after 1985, maybe we confuse ourselves with 'science'??
It can supposedly be used with coolants and is non toxic. Aparently you just add it at a rate of 1L per 80l of coolant.Iam tossing up the best way to run rmi 25 and if I should give it ago - keep in mind I need some form of coolant as I do drive and camp in sub zero temps . So how much do I keep in the system to keep it working as a anti freeze ?
