That little misunderstanding has killed off thousands of these cars.

Some links

This discusses dino-diesel and rug mixing. Some of the arguments and facts are relevant to the discussion at hand
mixing_gasoline_and_diesel.htm

Diesel has a lower auto-ignition temp then gas (Diesel at 210c, gas at 246c) as a source (auto ignition is the ignition temp without external help) In most diesel engines, the fuel is injected in the stroke at the point of highest pressure, and ignition rapidly occurs. The gas and diesel would ignite at almost the same time. The cylinder is going down due to the desired explosion.

The compression ratio does not drive the temp in the cylinder to extreme temps, the burning fuel does. Please review How a diesel works

I do recall stuff in the owners manual about mixing with GAS for thinning, but thought it was only for extreme cold. As I recall, Kero or D#1 was recommended as a preference. However, that owners manual was written long before modern winterized diesel formulations existed.

Last winter, I mixed commercial B99 50-50 with winterized DinoD when it was expected to be between 40-32F, and ran 100% DinoD when it was expected to get significantly below freezing (for us, that ~20F). That B99 is good to around 40F, and I've pushed it quite a bit lower than that since our weather has been so wierd lately (well, wierder than normal).

Data point:

8k miles on WVO/RUG blend up to 15% RUG. My engine hasn't melted yet.

Nuclear explosion? What is the half-life of gasoline anyway???

I have two 1980 300 TDs. On page 85 of the owners manuals it recommends blending up to 50% kerosene or up to 30% regular unleaded gasoline in very cold weather if #1 diesel fuel is not available. It says not to blend anything with #1 diesel fuel.
I have been running these cars on 90% settled and filtered WVO and 10% RUG for a couple of years.. Sometimes 100% WVO. This is in central California, mild climate. Steve

Although a little gasoline will burn just fine in biodiesel, gasoline has terrible "anti-gel" qualities. I tested some, and the biodiesel just precipitates out, leaving liquid gasoline and solid biodiesel. Not something you want to happen in your fuel system. Hopefully your filter plugs before your IP seizes from lack of lubrication.

And my owners manual specifies mixing KEROSENE in DIESEL, not gasoline. Kerosene is a better anti-gel for biodiesel, I would NOT consider gasoline.

Oh, Please....

How on earth can the fuel explode in such a dramatic way you describe--Come On!....

WHEN IT AINT EVEN IN THE COMBUSTION-CHAMBER UNTILL ITS ACTUALLY NEEDED TO BE BURNT!

First, induction-Clean air, Nothing more is drawn in...
Second, Compression- The Clean air, again Nothing added, is compressed...
Third-Injection- At the Correct Instant controlled by the injection pump and timing-device,--and in a Controlled, Metered manner, Fuel is injected into a hot Turbulent air-mass and -AFTER A SHORT DELAY- (Depending on the quality of the fuel injected-Good fuel of High Cetaine= Short delay, crap fuel, with Low Cetaine = Long delay...), the fuel will PROGRESSIVELY burn....
Fourth, -End of Injection, and Direct-Burning phase at the start of the power stroke...
Fifth,- end of Power-Stroke, start of exhaust-stroke....

Diesel Theory 101!

It is quite acceptable to add a little RUG to diesel-fuel of our old M.B. diesels, But I would advise against it in Common-Railers or anything Post 2000 year, Not due to combustion issues, but due to electronic and injection-system issues....
