What happens if I put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters.
Similarly the oil viscosity will be higher and oil thicker than specified during summers..
Which oil is thicker 5w30 or 10w40?

The end result is that your engine won’t last as long as it could. It might also mean an extravagant bill for an engine replacement or a sooner-than-expected rebuild.
How often should I change my full synthetic oil?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
How many miles can you go with full synthetic?

Should I use thicker oil in a high mileage engine?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
Will switching to synthetic oil cause leaks?
Switching to synthetic oil causes leaks: Generally, switching to synthetic oil does not cause leaks. It is true that synthetic oil is thinner than conventional oil and therefore flows more easily.
