The following is a picture guided walkthrough for my favourite/quickest trade route.

Its tried and tested; (almost) perfected, and with optimum equipment/loading you'll make 750,000 SD in 12-15 irl minutes - 6 hours game time. The route involves buying 45+ barrels of crude oil from Tarasov Oil Field and selling it to Eastport, Kolovy. You'll be buying the barrels for 20,000 each and selling them for 35,000 each, making 15,000 profit per barrel.

As well as being fast, a big benefit of this route is using very little fuel . Midway between Buy and Sell locations is a very large hill. After going halfway uphill, you can coast the 2nd half of the journey in neutral gear and/or with your engine off. If done right you can cover literally half the journey without even using your trucks engine!



Requirements

-Due to the route requiring off-roading, a covered truck bed is needed for best performance. An open bed can be used; however you'd fit less product and likely have cargo ejected when travelling the bumpy route

-Bigger = better. For maximum profit you want the biggest covered bed possible. This route was tested with the Zakmat's and capped out at about 42 barrels on board.

-Starting money; buying your first full load of oil costs almost exactly 1 million SD (based on the test numbers above) . You can start smaller if currently not able to buy a full load.

So you're in Kolovy with your truck, ready to make $$$ (Note: These screenshots were taken after my demonstration run. I started this run with $6,315,215)

From the top of the hill exiting the docks, head pretty much dead straight into the wilderness, towards the oil field/Lupova direction. You want to bare slightly towards the less steep part of the distant hills (picture 2)


When you start climbing , bare very slightly to the right; you dont want to be too close to the coast. Aim to be central/ staying in line with the middle of Kolovy behind you. (after the first run you'll get a feel for the easiest path, no wrong answer really, just feel it out)

The hill should be pretty easy to climb (3rd-4th gear in Zakmat) At the top you should see something like what's below. From this point you can go neutral gear/engine off and roll the rest of the way.
Oil field is behind the lowest hills, dead centre in the screenshot below






You should see an abandoned garage somewhere below you. If you see it, head straight past it and follow the direction of the dirt road just beyond it. The oil field is behind the low hills above and to the right of the garage in screenshot below.

I dont see the garage?

If you crest the hill too far to the right, you should see the oil field in the distance anyway. If you come up and dont see the garage or oil field, but very steep drops with hollows below them; you probably went too far left when climbing the hill, head right - away from the ocean/coast line, drop down the high ridge of cliffs and you'll be in the valley with the carpenter shop and garage, follow the only flat direction of travel and you'll come across the garage eventually.

At the oil field you'll see some porta-cabins, fuel tanker and parked cars clustered together (illuminated at night) Park up there and buy the oil from the stack of barrels to the side of the cabin.
Load as follows



Dont forget to fill your inventory as well (I was unprepared, so just dumped my smaller inventory items into the trucks cab)

Once you're loaded and ready to go, follow the dirt path back the way you came. However once you reach the point of narrowing (2nd picture), turn left off road. You'll see one direction that clearly looks far less steep.



^Garage is slightly to the right in this picture, head left instead, where my truck is pointing.
^top left of this picture.

Once you reach the top , you'll see Kolovy/ Eastport clearly in view. Now its just a case of getting down without flipping. Once again you can go neutral gear/turn off engine here. Its completely possible to make it from here, all the way into the docks without once needing to accelerate.

To the right may look more direct, but it gets tricky at the last section. I head right until the last section is visible, then turn left and go for the smoothest down ramp (Picture 3). Final technique is up to you.

You've arrived!
The drop off bay for selling crude oil is the furthest one, directly opposite you when driving through the entrance - between the 2 ship towers


I recommend reversing in, due to the tight space near the oil bay being almost impossible to turn round in.







And here we are. Nearly 3/4 of a million in profit , just dont forget to sell the barrels in your inventory!

Thats it for my first ever guide. Hope it helps some people start bringing in that easy profit :)

It may seem like effort the first time, but after a few runs you'll perfect the easiest/quickest route over the hills; and master loading up the oil quickly.

Its worth noting that in this example; I didn't fill all 10 slots of my inventory with oil, and I also failed to fit the max possible amount into the truck bed. As a result I only made about 700k, however when repeating this run more carefully; I not only completed it far quicker, but also made more like 750-780k SD.

Special thanks to @UnreasonablySaucyConcrete , who pointed out to me that crude oil was worth testing as a better route to my previous Lupova brick hauling run.

Happy Trucking!
