If the recommended oil is 5W-20, 5W-30 would work OK, but 10W oils would
not be recommended. The key is the weight of the base stock. 5W-20 and
5W-30 are made from the same 5W base stock. 10W oils are thicker and
won't flow as well. If the reason that 5W-20 is recommended is due to
tight clearances and small oil ports in the engine, a thicker oil could
cause oil starvation, leading to excessive wear and bearing damage,
especially if you live in a cold climate.

I'd have to re-check the manual, but I believe that all three weights
are OK to use given the right temperature range. 5W-20 is the preferred
oil, but I believe both 5W-30 and 10W-30 are acceptable.
Yes, all else being equal, 10W oils won't flow as well as 5W oils, but
all else isn't always equal. Viscosity numbers are given for a given
temperature (I forget the specifics now) and don't cover the behavior of
the oil at other temperatures. For example, a 10W dino oil will flow
the same as a 10W synthetic at only ONE temperature. At lower
temperatures, the more stable viscosity of a synthetic means that the
same weight synthetic will flow much more freely than the dino oil. My
10W-30 equipped minivan and truck crank much better at -10 than does my
Sonata with 5W dino oil.

You'll probably find that 10W oils are recommended for warmer climates
and summer use. I've never found any good reason to switch to thicker
oils in summer. As long as the upper end of the viscosity range is
adequate (the 30 in 5W-30) the heavier base stock isn't going to make
any difference and I'd rather have the better flow characteristics.
Out of curiosity, have you ever heard of anyone having an engine failure
due to oil that was insufficiently protective at higher temps (viscosity
breakdown)? It seems to be the thing most people worry about, but I've
never heard of such a failure. Using oils that are too heavy and cause
starvation seems to be a much bigger issue, at least in modern engines.

True. That's one of the reasons I use synthetic oils in my Elantra, both
in the engine and transmission. The transmission oil in particular makes
a big difference when temps are 0F or below.

True. That's one of the reasons I use synthetic oils in my Elantra, both
in the engine and transmission. The transmission oil in particular makes
a big difference when temps are 0F or below.

You'll probably find that 10W oils are recommended for warmer climates
and summer use. I've never found any good reason to switch to thicker
oils in summer. As long as the upper end of the viscosity range is
adequate (the 30 in 5W-30) the heavier base stock isn't going to make
any difference and I'd rather have the better flow characteristics.
Out of curiosity, have you ever heard of anyone having an engine failure
due to oil that was insufficiently protective at higher temps (viscosity
breakdown)? It seems to be the thing most people worry about, but I've
never heard of such a failure. Using oils that are too heavy and cause
starvation seems to be a much bigger issue, at least in modern engines.

I can't say that I've ever seen a failure that I could attribute to the
oil, other than the lack of it. I run synthetics simply for the better
cold starts in the winters I live in. Otherwise, I believe it is
overkill for the type of driving I do the rest of the year.
