What is your actual location?
What do you mean by "hot weather area?
-- Are we talking mild winters and summers,
or Arizona w/ 110F Summers and cold Winters?
What vehicle and what year model?
Dodge recommends for most gasoline Dakota's a 5w-30 motor oil.
__________________________________________________
I believe that if you live in an area where the Winters are mild and the Summers hot ... the less spread the better ... therefore I might recommend a 10w-30 ... otherwise I would probably recommend the 5w-30.
FYI -
Almost any Synthetic "X"w-30 will work ... and a 0w-30 and a 5w-30 will perform better when the temperature is cold ... and give you slightly better gas mileage.
__________________________________________________
Which brings us to the topic of:
VISCOSITY ... in the general term defined as " a fluids resistance to flow". It's a measure of the internal friction of the fluid or the resistance to the movement of one layer of molecules relative to an adjacent layer.
THE LOWER (SMALLER or FIRST #, as in "10w-_) NUMBER.. is the Cold Cranking measurement, made at low temperatures, using a concentric cylinder viscometer to predict the oils cranking resistance in an engine during cold starting.
The measuring devices, or viscosmeters, most often used are in the form of close-fitting concentric cylinders. The fluid being evaluated is placed between the cylinder walls, the outer cylinder is held stationary and the inner cylinder is rotated. The speed of rotation is measured for a given force to calculate the viscosity, most commonly reported in cp or centipoise units. Also known as Absolute Viscosity.
THE HIGHER (BIGGER or SECOND #, as in "-30") NUMBER...is commonly measured in capilary tubes, in which the time for a fixed volume of fluid to flow through the tube under gravity at operating temp (100c)is measured and reported as cSt or centistokes. This is used most commonly to report the normal operating viscosity of motor oils or the higher number.
" 0W- " is a viscosity GRADE, not a viscosity MEASUREMENT.
When testing for cold fluidity, the temperature is lowered approximately 5 degrees centigrade between each test.
The Cold Crank Simulator Apparent Viscosity is tested at:
-20 C for 10W-
-25 C fpr 5W-
-30 C for 0W-
It is my understanding that the oil has to be labelled at the lowest temperature it meets the specifications.
It may not be long before someone comes out with a " -5W-30 " which would correspond with -35 C.

Miami is very mild winters and the summer temperature has never exceeded 99 degrees F. I know because I lived there for 3 years from 1991 - 1994 on Brickell Key.

What year and model is your Dakota?
It does not matter really ... Dodge recommends for most gasoline Dakota's a 5w-30 motor oil ... and you could use either 5w-30 Synthetic Motor Oil or 10w-30 Synthetic Motor Oil.

Since when did Dodge specify 5w30 for Dakota engines? Maybe the 4.7 and 3.7, I don't know, but the 3.9, 5.2, and 5.9 take 10w30.

Hey Canadakota,
I live in Edmonton, and I'm sure we get colder here than you do! I used to switch to 10W30 for the summer months and run 5W30 for the winter, but if you compare the viscosity curves for 10W30 synthetic, you will see that even at about -40C the viscosity is close to the same as that for 5W30 dino oil. So I decided to go with running 10W30 Amsoil year round. The 10W30 keeps a better viscosity at the higher temps, and since my engine pretty much runs at the same temp (regardless of -40 or +40, I wanted to keep the better viscosity when the engine reached operating temp.
Hope that helps you out.

Ya, we rarely see -40 weather here but with the wind chill factor, it gets pretty damn cold at times. That makes good sense what you say about the oil. I was just curious but I`ll stick to the 10w30. Its starting to get cold and my truck never has problems starting, so I wont change a thing. Good luck to your Oilers.

luke;
5W-30 is the recommended grade as per the factory owners manual for temps 'during the next oil change period' from 0-75*F iirc....it then goes on to say 10W-30 for 20-100(iirc).....from my 2000 CC manual....after four years of ownership, i finally read through it, and was surprised at the amount of actually useful information in there....
