None of the above testing involved Modifying the Injection event or fuel-system. The engines used for the most part were Direct-Injection and NOT Pre-Chamber engines--They are Very Different....

DI engines perform poorly on Veggy-Oil with regards longevity IME....

Constant-load/speed found in agriculture/generators is NOT recommended for using veggy --even when the fuel-system has been modified--

Constant load/speed even using std. diesel cause excessive carbon build-up anyway...--They coke-up.

Flawed testing IMHO I'm afraid.....

Next naysayer please.....
