Low sulfur fuel and additives

[Jeff Miller]

FWIW my car manual specifies #1 fuel for temps under 32*F, or to mix
30% kerosene with #2 diesel for temps between 14*F and 32*F, ...
50/50 for temps below 14*F. Never to mix #1 and kerosene.

Many of us on various Mercedes Diesel forums have had fuel leaks,
pretty common, I've had two minor ones this fall on one of my cars.
The incidence with existing vehicles will likely increase with the
ULSD especially in older o-rings. Not much can be done about it,
various additives could in theory help, more can be learned from
Biodiesel and WVO forums as there are additives used in cooking WVO
such as benzene and naptha that could increase seal swell.

ULSD is here, it is staying. Watch for leaks, raw diesel is an easy
smell to notice just after shutdown. If you smell raw diesel you're
getting a leak, find it. Increased fuel consumption and rough idling
are other indicators, and watch the engine oil for leaks into the
oil which I know from experience can grenade an engine if it gets
enough diesel oil to hit the crank/rods and run-away (no way to shut
down). A drop in oil pressure might indicate thinning oil from a
leak.

With ULSD it is now more important to use algaecides, watch filters,
use quality oil, and notice smells or fuel mileage changes.
