Understanding the Post-Injection Problem - Biodiesel Magazine

 

Great find!

 

Fuel dilution of oil is the problem not bio! I would say trucks with a lot on idle time, in town driving, has this problem more than bio. I have run 99% 50% 20% sent truck was new. My Truck has never made oil, ( change 3,000 - 3,500 miles ) very little in town driving, trips are 40/50 miles at time, no idle. The biggest problem with bio is bad made product!

 

I see what you're saying, but read the article!

It mentions how bio is more likely to wash the cylinder walls and make it past the rings due to it's composition, and that tests have shown that the percentage of bio making it into the crankcase is WAY higher than the percentage of bio in the fuel.

Also note this in the 6.7L diesel supplement, which happens to be certified to run B20.:

This engine is specced to run 10w30 oil for year-round use, yet requires thicker oil for bio. I suspect this is due to the increased fuel dilution with this type of fuel, as noted in the article posted by the OP.



There is a LOT of good science there, it's very tough to argue with!

 

I personally shy away from the stuff. Less energy and cost the same or more. Economically that does not make sense to me.

I once tracked a tank of that stuff. Running empty accross IL of course. Got around 11 mpg's if I recall. Every other tank was in the 14's.

Granted that was when the truck was new. As I now can routinely get in the 16's.

 

I shy away from it also. I just do not get the performace. The last time that I knew that I ran it, I changed filters and "oh" what a mess. I have noticed several of the Loves are dispensing B5 towards the Houston area.

 

I pumped about 25 gals of it once before I realized what I was doing and stopped. My MPG dropped significantly.

 

 

I'd rep for that one but I gotta spread the love first....end of debate.

 

WOW! That is fubar! The most mine have ever been was slightly discolored how did you get that to happen?

 

They'll either look like that, or have a coating of "butter" on them.

 

Oh my gosh! I hope this is a joke! This is painful!

 

Ah, but look at it from another perspective.

That filter did it's job! Better the filter stop it than the injectors or HPFP!

 

Customer brought it in for "Low power, hard start". Said it had been that way for a while.

 

If it had been that way for awhile what are the odds it harmed his HPFP?
