What is the tax-free amount of gas I can bring to Lithuania from Kaliningrad?

I am planning a trip from Kaliningrad to Tallinn. Since gasoline in Russia is cheaper than in Lithuania, it is useful to fill up a canister and bring it across the border to the Schengen zone.

What is the upper limit for tax-free import of gasoline (for a car) in a portable container to Lithuania from outside of the EU? For Estonia for example it is 10 liters but I can't seem to find a similar source for Lithuania (this resource for example does not list fuel).
