Re: RS and "bozos"

Tom,  Just a note of encouragement.  I didn't think your reply on this 
topic was over the top at all.  I really enjoy reading your stuff.

One nit to pick though, is that you have several times referred to the 
Lentini holed piston.  I think he acknowledged that he was in error 
with his advanced timing recommendation, and I would suspect that that 
was the cause of this failure.  Much more so than the mid grade fuel.  
Of course, these two things work together, but I don't think he was 
wise to advance the timing just because you can on most engines.  With 
a compression ratio like the oil heads have, timing is not something to 
second guess the factory on.

On the other hand, BMW has had a big thing about premium gas for many 
years.  This comes from the days when their engines were carboning up 
on lower octane fuels that didn't provide the detergent package that hi 
test did.  The gas companies now provide complete detergent packages in 
all grades, and this is no longer the problem it once was.
