AFAIK, we haven't tested any VO or even BioFuels - which means none of
*my* customers have submitted alt. fuels for testing. Perhaps the Lab has
tested some? I'll chec I'm just guessing, but I know some people using
alt. fuels are trying to save money so they may not think spending money on
oil analysis is valid.
I'll check with the lab and see if they have anything they can share.
Don't know how long it takes or if the alt fuel will get the blame but I
would think some of those engines are failing. Perhaps that's being blamed
on age or something else?
What do ya'll think?

>>Howdy -
>> I know with fuel being close to $5/gal in many areas, it's tempting to
>>try and save a little money by using an alternative fuel. I've spoken to
>>some diesel owners who were using veg oil to power their engines and they
>>were getting some amount of the veg oil past the rings and into the oil.
>>Same for Biofuels - unfortunately some of these concoctions do not mix

>>with lubricating oil. One owner found his oil had turned rubbery after
>>using veggie oil to power his diesel. Naturally the engine was damaged

>>lack of lubrication.
>>
>> I believe all engines - especially diesels due to their high
>> compression
>>levels experience "blow-by" (when combustion gases get past the rings into
>>the crankcase & oil) which gives an opportunity for the various
>>alternative
>>fuels being used to enter the crankcase and mix with the lube oils.

>> This makes Oil Analysis important IMO, as you can learn how much of
>> your
>>fuel is getting past the rings - which will have an impact on the oil
>>change
>>intervals. Don't buy from me if you like, but consider getting an
>>analysis
>>done somewhere to establish a benchmark so you'll have an idea of how much
>>alt fuel is entering the crankcase. Or perhaps you can determine this by
>>other means?
>>
>> Since there are so many variables when discussing alt fuels (sources,
>>filtration, purification, storage, heating methods, etc) it's difficult to
>>know what alt fuel might be compatible with the required lubrication being
>>used in the crankcase but IMO there is a risk when using these fuels you
>>need to be aware of.

>>Good luck -
