I spoke to a chemist at Pen-Ray last week. I told him what I drove and he said either 2000 or 3000 would work for our cars but, suggested 2000 as it is formulated for non anti-freeze applications.

I too used No-Rosion for many years without problems but, have had to look elsewhere as I started having trouble with foaming.

The Pen-Ray folks also mentioned they use an anti-foaming agent their products.

Happy Motoring,
