labeled ask the station operator what fuel is being dispensed before
filling up your vehic le .
Service stations offering diesel fuel are generally located on truck
routes or major highways. Directories of diesel fuel stations are
usually available at diese l fuel stations.
Some states in the USA require permits to purchase diesel fuel.
Check with your State Motor Vehicle Department.
Diesel fuel may not be available outside the USA and Canada . Be
su re to check before traveling to other countries .
Winte r ope ra ti on
At temperatures be low 20° F (- 7° Cl, Diesel fuel No. 2 loses its fluidity
due to wax separation, which may c log the fuel filter or tank filter
and keep the engine from running.
To he lp the filter from being clogged by wax, the fue l filter in your
vehic le is automatically preheated. Preheating the fuel fi lter makes
operation of your vehicle poss ible with Diese l fue l No. 2 down to -
10° F (- 24° Cl.
If you expect tempe ratures below 5° F ( -15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is sufficiently winterized for the prevai ling and expected temperatures .
If not winterized or insufficiently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during
the warm -up per iod in winter. It is also normal when whitish -blue
smoke comes out of the tailpipe after starting and dur ing warm-up.
The amount of smoke depends on the outside temperature .
Do not let your diese l eng ine idle unnecessarily after a cold start.
Driving off slowly will shorten the warm -up period.
