P-39 and P-63 engines just got the same coat of Adamantium paint when assembled or painted on Russia that the local planes, be sure.
From a post I made several years ago:
http://www.sas1946.com/main/index.php?topic=17831.0
"The DB and Jumo engines cook very quickly when damaged, if the engine is smoking it dies in 3 or 4 minutes (depends on the power setting), if you are leaking it start to overheat pretty quickly at combat power and dies in 5m top, only going to cruise power give you more time to escape, but in no way you can pull the crazy stunts the P-39/63 does at full power when leaking or even smoking.
Very few times I got a engine instantly stop with the dead prop, but it happens, sometimes I saw hits then a high pitch from the RPM controller going out of control and the engine seized. The radial engines can survive hits and still work for long times, giving less power off course (less pistons working) if you are not loosing much oil or fuel (usually the fw190 get the fuel lines leaking on the cowling and even when the engine still works you loss all your fuel in 3m). Sometimes I noticed hits on La-5 cowling (little bullet holes) and no leaking whatsoever but that could be right or error on the damage decal.
There are several DM errors on the planes, a structural weakening MOD by damage limiting the maximum G stress allowed would fix for example when you put 1 or 2 MK108 shells in a P-51 wing or P-47 mid fuselage (did that yesterday) and the damn plane keep fighting, turning, diving at full combat power. Only showing some holes on the skin instead of breaking the plane. The now very limited G stress will only allow for a escape run, if the plane keep tryng to fight, it should break right there. So the errors on the DM would now be atoned at least in a simple and broader way. No need to check and fix every f%&%ck·$ing plane DM."

OK guys, after 90m of searching, quick resume:
OIL (pilot manual) 9.4 gallons (35.58 Litres) for the P-39 L/K
P-39Q 8.2 US Gallons (31.04 Litres)
P-63 used the same engine (more advanced model only) and similar airframe, couldnt get the manual but from all the warbirds I found OIL tank info, they were pretty much equal size, even the P-38 had a similar sized tank for each engine to the Spit or Mustang
For comparison:
The Spitfire XIV, without a long-range tank, carries 110 gallons of fuel and 9 US gallons of oil.
Bf-109G2 One light-metal oil tank, type NKF. Oil capacity 8.1 gallons (30.66 Litres) with an additional air space of 1.3 gallons.
The Mustang III with maximum fuel load has between 1.5 and 1.75 the range of a Spitfire IX with maximum fuel load. The fuel and oil capacities are 154 gallons and 11.2 gallons respectively, as opposed to 85 gallons 7.5 gallons of the Spitfire IX, both without long-range tanks
NOTE: PROBABLY IMPERIAL GALLONS BECAUSE 7.5 Imperial gallons = 9.00712816 US gallons

So.....can we get a ending to the "Highlander" Allison engines now??? By the way, the oil tank on the P-39 is behind the engine, close to the tail, so when you get a 6 o clock shot at them that is the first thing to get screwed.
AND REMEMBER GUYS THAT BESIDES THAT "BUG" I WAS WONDERING ABOUT A "COMBAT DAMAGE REDUCING G STRESS ENVELOPE LIMIT" MOD
