| The Amsoil and Stanadyne are both great products. Both offer high concetrations of cetane improver and lubrication additive. The heavy Duty Diesel additive by Amsoil seems to have a little more of the lubrication additive in it than that stanadyne.
Power service is good too, but is more dilluted.
PS> Overuse is not harmfull with diesel additives, only a waste of $$
Happy dieseling!! |
