55-98 vol % isoalkane solvent of the a total volume of the penetrating oil, wherein the isoalkane solvent contains at least 85 wt % isoalkanes of the total weight of the isoalkane solvent and wherein isoalkanes in the isoalkane solvent contain at least 85 wt % in a range of carbon number C14-C20; and
2-30 vol % oil derived from biological sources of the total volume of the penetrating oil.

2. A penetrating oil comprising:
55-98 vol % isoalkane solvent of the total volume of the penetrating oil;
2-30 vol % oil derived from biological sources of the total volume of the penetrating oil; and
a lubricity additive 0.1-5 vol % of the total volume of the penetrating oil, the lubricity additive containing 5-50 wt % solid particles and 50-95 wt % carrier oil of the total weight of the lubricity additive.

3. The penetrating oil according to claim 1 , wherein the penetrating oil selected to contain 2-20 vol % oil derived from biological sources of the total volume of the penetrating oil.

4. The penetrating oil according to claim 1 , wherein the oil derived from biological sources is an ester oil derived from at least one or more of biological sources.

5. The penetrating oil according to claim 1 , containing 70-95 vol % isoalkane solvent of the total volume of the penetrating oil.

6. The penetrating oil according to claim 1 , wherein the isoalkane solvent at least 93 wt % isoalkanes of the total weight of the isoalkane solvent.

7. The penetrating oil according to claim 1 , wherein the isoalkane solvent comprises:
at most 98 wt % isoalkanes of the total weight of the isoalkane solvent.

8. The penetrating oil according to claim 1 , wherein isoalkanes in the isoalkane solvent contain at least 90 wt % in a range of carbon number C14-C20.

9. The penetrating oil according to claim 8 , wherein of the isoalkanes in the isoalkane solvent at most 95 wt % are in the range of carbon number C14-C20.

10. The penetrating oil according to claim 1 , wherein the isoalkane solvent has a flash point which is above 60° C., as measured according to ASTM D 93-2010a (2011).

11. The penetrating oil according to claim 1 , wherein the isoalkane solvent has a pour point that is below −30° C., as measured according to ASTM D 5950-2014.

12. The penetrating oil according to claim 1 , wherein the isoalkane solvent has a kinematic viscosity that below 12 mm 2 /s at 20° C. as measured according to ENIS03104/1996.

13. The penetrating oil according to claim 1 , wherein the isoalkane solvent has a kinematic viscosity that is onc or morc of at least 1.0 m-m-2 / s, at (cast 2.0 mm2 i sandler--at-least-3-0. mm2/sat 20° C. as measured according to ENISO3104/1996.

14. The penetrating oil according to claim 1 , wherein the oil derived from biological sources has a higher kinematic viscosity than the isoalkane solvent, the kinematic viscosity of the oil derived from biological sources being at least more than 8 mm 2 /s as measured according to ENISO3104/1996.

15. The penetrating oil according to claim 2 , comprising:
0.5-2 vol % lubricity additive of the total volume of the penetrating oil;
wherein the lubricity additive contains 10-40 wt % solid particles and 60-90 wt % carrier oil of thea total weight of the lubricity additive; and
wherein the solid particles of the lubricity additive are boron nitride particles, graphite particles, molybdenum sulfide particles, or polytetrafluoroethylene particles, or a combination thereof.

16. The penetrating oil according to claim 1 , comprising:
a propellant 1-10 vol % of the total volume of the penetrating oil;
wherein the propellant is selected from propane, butane, CO 2 , N 2 , or air, or thereof.

17. A method for producing a penetrating oil, the method comprising:
