FIRST GLITCH IN THE BIG RED FIRE TRUCK;
Since the 10,000km service (now has 15,000km) the fuel economy has been rising. Earlier in the year I towed the van (1750kg) from Melbourne up to Jindabyne through the Snowys and across to Merimbula and back to melb. 2,200km's at 12.1 l/100. Totally happy and acceptable with that considering the hills and sitting on 100kph on the highways. Consistent with other trips towing the van.
Since the 10,000km service noticed the consumption going up around town whereas I was getting 7's l/100 am now getting 11's and 12's l/100.
Just got back from a 4,500km trip towing the van and the consumption has gone up to 14.5 -15.5 l/100 with easier conditions.
Driving style is the same.
Fuel range has dropped from the original 1200km's per tank down to 800km's per tank with no van on.
This week noticed high idle and hit the go pedal to clear it maybe.
Noticed that the rev counter could only go to 2500RPM's. Tried it several times and same thing.
Did it in Park with brake on. Did it in Neutral with park brake and foot brake off.
2,500 RPM's the max.
Rang up a Jeep dealer and spoke to workshop about it. Muganic said "No worries mate, itsa diesel and they only rev to 2500 anyways. Thats where you get all your power at."
Quoted the specs to him then. Sure max TORQUE is at 2,000revs (570nm) but the POWER is 184kw at 4,000revs!!!!
So how do I access all this you beaut power if I can only wring 2500 RPMs out of it Mr Muganic???
Will probably have it on the computer in the workshop next week to see whats wrong.
Strangely enough the take off and power through the gears are Ok under heavy pedal but the gears change at 2100revs any way in Sports mode and Economy.
Had no probs pulling the van except for the heavy fuel concumption.
