T&T: you talking to me?

[John Baker]

I will be purchasing a boat with a Yanmar 4LHA-STP and the manual does state a recommended cetane rating of 45.  The PO says he does notice a difference in the performance and overall smoothness of the engine when using fuels of different cetane ratings.  He uses a Cetane booster to achieve this. 
   
  Trawler on,
  John

  Of course I apologize to Ed, as I was not directing my comment to him. 
Please note that I only replied to the List and removed all other 
addressees - I did not "Reply All" for this very reason.

I think that one of the writers conveyed the image of speedboat guys sitting 
at a yacht club bar suggesting that more expensive fuel gave better 
performance. I am not condemning the messenger, rather the consumers who 
could come up with such a stupid, illogical idea concerning diesel fuel.

At least with automobiles we get a recommended octane rating - yet we do not 
get a recommended cetane rating for our diesel engines. Does anyone have a 
manual, perhaps from a newer diesel's manual, which prescribes a certain 
cetane level? Have you seen a pump with a cetane level on it?

I *suspect* that long-stored diesel, exposed to air loses some of its cetane 
rating - but, I don't know that.

Lastly, is there anyone on this list who seeks out the most expensive gas 
station so that they get the best performance from their car engine?

Finally, about 5 years ago, Yanmar raised the horsepower ratings of its 
unchanged engine models. Why? Because they started to use USA diesel instead 
of their own and our fuel (I assume that Canadian fuel is the same) allowed 
their engines to develop more horsepower on a test stand.

When we switch over to EPA mandated EU-type diesel, will we lose horsepower/ 
efficiency? I *believe* the answer is yes.

Again Ed, I apologize,
Ron Rogers

You posted...Only a complete idiot would think that he is getting better 
diesel by paying
a higher price.

I started the thread by asking a legitimate question about cetane ratings 
and whether higher priced fuels have higher cetane ratings and therefore 
might be worth the higher price. To call me an idiot for asking that 
question is insulting and requires a public apology.
