Just read a product description for a diesel additive that said it DIDN'T contain harmful cetane improvers/additives. I never knew there was a danger. Why is that?

__. Yeah, Bill, there's something about the whole "marketing speak" of this that makes it pretty unintelligible in a technical sense. If I had to guess, I'd guess that they're talking about alcohols -- which are often added to gasoline fuel treatments as water removers -- these really don't have any place in a diesel fuel treatment. But why they'd call alcohols "octane improvers" is beyond me.40X40 said:Thanks for the link!
I suppose a cetane improver would be counter productive in a gas engine.. and this product claims to be made for both gas and diesel fuels. Perhaps this use in gasoline is where they find the C/I additives to be 'harmful'? (snip)

Straight ethanol has an octane rating of about 120, versus 87 for RUG.mrGutWrench said:But why they'd call alcohols "octane improvers" is beyond me.
__. Yeah, but do you see any improvement at "attitive levels"? I can see blending 20% to raise octane but what good will 4 oz. do you?tntdifan said:Straight ethanol has an octane rating of about 120, versus 87 for RUG.
The operative word is "harmful"; not "cetane".MalcolmBurke said:Just read a product description for a diesel additive that said it DIDN'T contain harmful cetane improvers/additives. ... Why is that?
