45:1 from BRP ???
The infamous 45:1 from BRP appears to be if you can reach 17 mpg
Maybe with a stock 1" track and 29/49 gearing.
Earliest info said to expect 14-15 mpg on hard trail riding
11 to 13 mpg with a studded 1.24" track running 27/49 gearing. Ball Park Figures
It's not about being precise, but rather being in the ball park.
Example: 13 mpg @ 100 to 110 mpq.
The next day it consumes 150 mpq.
There might be a problem with a frayed oil cable.
Say the oil cable adjustment is set to 18mm.
With a preset gauge using a piece of anything, it takes 60 seconds to check.
I have seen frayed oil cables so loose that it was obvious just by looking at the adjustment. Disproportionate Fuel/Oil Consumption
One reason for more oil is the real time fuel consumption is unknown.
At least three factors affect fuel consumption disproportionately to the oil.
Engine temp greater than 90C
Exhaust temp greater than 600C
Ambient temperature as it gets colder. Forget the 45:1
Throw that ratio into the garbage.
It has no value without the fuel consumption. Graduate the Oil Tank
Graduate the oil tank to 1/4 quarts.
Figure oil consumption per quarts.
Then compare with Fuel Consumption.
XPS Mineral works great with the sea map.
