Personally, I want some cold start capability down to at least zero F.
.....
Hmmm. Whose testing dollars were these? If they were mine, as in taxpayer dollars, how about testing a formulation that will meet a fundamental expectation, like a cold start!
Did you read the part that says "Cold Starting does not refer to cold weather operations such as winter temperatures?"
Lead will go away because of its impact on the environment and cost to produce and transport it. There was a time when it was in paint but no more and we seem to not miss it much in paint.
We do not miss it in paint because we no longer remember how good paint was when it had lead in it. Just like we are starting to forget how nice paint used to spray when we were allowed to have VOCs and how cold your air conditioning was when you had freon.
As suggested, I do not know if there is proof that 100LL lead is a health hazard. People just resort to "it is politics" to justify the effort.
DDT may not have been the hazard thought decades ago and I have heard unconfirmed comments that millions have died in Africa since DDT does not control mosquitoes now.
Does a small group of people spouting uneducated opinions about the environmental consequenses of lead or DDT really belong on an RV forum?
