That depends mostly on the specs of the oil. However, assuming it has the right specs for your engine, 5-30 is a good allround viscosity. Personally i use GM 5-30 in winter and 5-40 in hot weather.
I live in a hot state under slightly hills. The owners manual recommends 5w-30 And it even says it on the actual dipstick. And that's the kind I always use. I accidentally bought one quart of 10w-30 and 3 quarts of 5w-30. I dumped all of it into the engine, not knowing one of them was the wrong kind until after when I disposed of the empty bottles. And I do live in a hot state and my car does hesitate going up hills or heavy acceleration. But after putting one quart of 10w-30. A car actually did better than before. It ran like a new car. I didn't know that. was panicking when I accidentally put one quart of the wrong oil. My car also leaks oil so I'm kind of panicked even more when I accidentally did this. My car has 250,000 miles so hopefully I didn't do any major damage
Hi Bryan.. You likely didn’t cause any damage by mixing 10w-30 with 5w-30, especially in a hot climate. The slightly thicker oil (10w-30) can provide better protection at higher temperatures, which might explain why your car ran better. Given that your engine has 250,000 miles and leaks oil, the thicker oil may have also reduced oil loss.

100%, Great point!
10w 30 is better for hot weather and more aggressive driving. Not 5w 40 that’s European oil.
What do you recommend for a 1995 Nissan Altima? 5w-30 or 10w-30 in California? The mileage is 64,000
Is the wear not the same if the visocity is still the same once warmed up ? W30 ?

Super low height for less friction for better fuel economy but bad for wear.
Great point!
