Can someone tell me the difference between the blue and the pink oil that comes with Daiwa reels?

I've noticed no difference in the blue verse red oil that they supply. I've even got a few bottles that are a gold color. All seem to be low viscosity and work well for spool bearings. 

Look into Yellow Rocket Fuel.  An excellent bearing oil.

the oil(fat) in avocados is mono-unsaturated.

Besides the color I'm going to go out on a limb and say they are probably the same. A standard 3n1oil works great and I suspect that is what many are selling colored or possibly a variant of. From the ones I have that seems to be the case.

I don't know Daiwas reasoning to the different colors but I can assure you that any colored oil or grease is just dye that plays no role in the quality or lubrication of the product. 

Thanks.  I have many of these in both colors and wasn't sure if the color was indicating different viscosities.

Great chart Molay.  Two comments.  Oil viscosity is highly dependent on the temperature.  Some are better than others at maintaining a viscosity over a temp range.  Also, you should be aware that very low viscosity oils will be slung out of your bearings faster than a thicker oil will be, and so need to replenished more often.  So choose an oil that agrees with your re-oiling habits.  I like servicing my bearings twice a year, with oil added periodically during the season.  I like a medium viscosity bearing oil like Yellow RF or Reel Butter.  They stay in the bearings for a period that agrees with my servicing habits.  Nothing worse than having a reel start screaming at you for service when you're on the water fishing.
