The question is somewhat unclear, but if you're asking if it's okay to mix synthetic-blend motor oil with full-synthetic motor oil, then the answer is yes.
However, it somewhat defeats the purpose of paying extra for full-synthetic oil.
Full-synthetic oils lubricate better than conventional and blended oils, and are more resistant to breakdown. This doesn't mean you should go longer between oil changes, though. No matter how good the oil lubricates, it still gets contaminated with particles from the combustion process and needs to be changed. The advantage is that over a long period of time, full-synthetic oil's better lubrication will protect the interior of the engine from heat and friction better than conventional or even synthetic-blend oils. With all conditions being equal, the engine treated with full-synthetic oil will retain its original performance and efficiency longer than the same engine treated with the alternatives. How much? That's a WHOLE different question!
Synthetic-blend oils take advantage of the superior lubricating properties of full-synthetic, but at a lower cost by blending full-synthetic oil with conventional oil. It is a slight improvement, but generally won't make a considerable difference in the life of your engine if you maintain it properly and change your oil regularly. Again, contaminants are the biggest culprits in engine deterioration, not cheap oil (usually, there are exceptions).
Mixing synthetic-blend oil with full-synthetic won't hurt anything at all except for slightly downgrading the superior lubrication properties of the full-synthetic oil. Mixing in conventional oil is also acceptable, effectively producing a synthetic-blend oil. Just be sure to use the proper oil type as called for in the owner's manual.

No they shouldn't be mixed as they have different viscosity Actually, yes you can......but you are wasting your money. Mixing the two reduces, significantly, the positive effects of the synthetic oil. Only do it if you have to, but they are compatible. There are oils available that are a synthetic blend of standard oil and synthetic oil.
