Dear all
I have just finished a calculation for my weekend trip cost to a nearby town 230km south of Ulaanbaatar 50% offroad. i filled my tank just outside of southern checkpoint and i clocked exactly 76 liters of AE92 and took off to my destination, some food, my backpack full of winter clothes (20 something kg), tent (50kg) and full tank. no snow at all on freeway half the length and compacted snow off the highway for the rest of my leg. Outside temp -25c with headwind (almost doubles the chill) coolant temp never reached half the gauge (only one fourth all the way) with regular Siberia antifreeze mix up to -50c so it's a fairly good mix.
winter tyres and no roofracks or anything, speed constant 50-60kmph engine rev 1600-2000rpm
got to the town and light came on (230km) filled my tank and exactly 74 liters this time, scratched my neck in disbelief and went to play around on the fresh snow for like 10 mins, did not get bogged or anything, no spinning tyres, camped, met my friends, idled for 25min to keep it from freezing. Headed home, this time wind from back, rolling hills (same route) speed little less (40-50kmph) with 300kg of butchered cow in the back. and only 25km short of my home just outside the checkpoint i filled up the tank first time, engine died.
grabbed my canister and walked 8 km or so to have it filled, this time it's 5pm and already dark, -30c or something.
10 liters in 20 liter canister and the rig would not budge (still starving of fuel) went back and got another 10 liters and engine started to run but very rough like a diesel (NKNKNKNKNKNKNKNKN). but first thing is first, i took off anyways as i have already lost hour and a half walking to and from gas station in cold.
got into my garage and just as i was parking, engine cut off. fine, i got home atlast, then went to check for spark plugs, wirings they are fine, nice and dry (all new but i still checked as i do not have full confidence in chinese parts)
I am intrigued 460km total distance with little idle and burned almost 140 liters of fuel (not winter blend) clearly there is something wrong which could have left me frozen dead in the wilderness.
this evening after work (few hours ago) i refilled the tank and 78liters. back in the garage, i heard this zzzzzzzzzz sound coming from the fuel tank and exhaust sounds like V8 (PLPLPLPLPLPLP) smoke is not continues but (PLPLPLPLPLP) no color change in smoke but clearly PLUTTERING PLPLPPLPLPLP. Did the fuel pump gone toast? there is no odd sound in engine this time, no diesel like NKNKNKNKNKs.... I am speechless... what do i do? sh*tty milage in winter is normal but returning little over 2 km to the liter seems really odd to me even by Mongolian standards
oh oil is W30 siberia moly blend syntechic.
