i don't disagree with that at all. However very often the best for the application is also the better product. Our Range Rover will run on 87 octane but the engine was designed to be run on higher octane so that's what we run it on. The engine in my new pickup was designed to run on 87 octane. It will actually run on E85 although the manual is worded in such a way as to imply one would be a fool to do it.
. So i run it on 87 octane.
We use Cat diesel coolant in the engines on our boat. Is it absolutely necessary? Maybe not. But I prefer to follow the advice of people we know who are actually in the diesel engine manufacturing industry rather than a lot of conflicting anecdotal opinions on an amateur boating forum. And since nobody has said that coolant formulated for diesel engines is bad for the engines in our boat, it makes no sense to not use it, particularly when the overwhelming opinion of the folks we've talked to in the diesel engine industry is to use it.
In the case of coolant, the cost difference between using diesel coolant and the automotive "green stuff" is insignificant. Particularly when one figures in how seldom one has to buy it. It's not like fuel, which one has to buy all the time.
So that's why we do what we do. What other people do is what other people choose to do.
