My wife and I both run B99 in twenty year old Mercedes diesels. Her 240 D experiencing a small diminishing in torque, but with replacement of oil filter should clear up; my 300 D, no problems currently. We put in perhaps 250-300 miles/month each, so it isn’t much. My 300 D has very good torque.
No problems with oil filters or lines yet. We’re waiting. At first, we mixed petrodiesel with B99. Now we’re 100% B99 after a couple of fillings.
Feels great not to be spending money at the Big Oil Companies. Exxon made $40 billion last year, the most revenue of any company in history. They’ll use the money to dig deeper in the earth and at sea, but the era of biofuels and other alternatives is here, no turning back.
We need to get the word out. B99 and the others work. And, the good news, you’re putting out a fraction of the C02’s.
