This is not an issue for a one time top-off. I would always use the manufactures recommended oil and filter when doing a full change however.
ONE NOTE: 40w oil is sometimes used in older/worn engines. It is slightly less viscous and will provide a better seal between highly worn parts.

No, it doesn't matter. Really the recommended oil should be used if you are under warranty but since your not...the only difference in weight is how thick or thin the oil is. You would want a thicker oil in the winter but it is the perfect time of year to use 1040. Better than no oil at all! : )

There are no problems with this. Remember when you are talking oil, the 30-40 second part refers to the viscosity or how thick it is. 40 wt oil is alot like pancake syrup and it will mix with a less thick one like 30 w. The first part is how cold it could be and have the oil perform. So, 5-40 w oil will work in -5 degree weather (cold) and have a thicker consistancy than the typical 5-30w oil. But it's okay to mix them. I hope this explanation is helpful to you, good luck.

It depends on what you have been using, if any kind of syn. oil has been used do not put reg. oil into the car. Also look to see what the manf. recomends. For top off in emergancy situations use what you can find but make sure you have the oil changed.

No manufacturer recommends using 40 weight oil anymore. It tends to cause sludge (gunk) in your engine, and actually provides no benefit over 30w. Also, try to find out what (name)
brand was used previously, because there are differences in the
formulas, and you should stick with Pennzoil (or whatever) if that
is what the last owner was using in it.

it will not hurt your car if you are toping it off with it..just make sure you use the proper oil at the next oil change
