[T3] ZDDP: How much is too much?

[Don Robertson]

I talked to the Lucas distributor in Vancouver, and he recommended 
this:  http://www.lucasoil.ca/products/product.asp?id=9&cat=HeavyDuty

It is the right weight for summer use in an air-cooled engine, and 
has the right amount of zinc to protect a flat cam diesel engine. so 
you will not have to add any additives to it.  Just don't try to 
extend the drain interval unless you have a good oil filter installed 
on the engine.
