Hello,

Toyota specs 5W30 for the engine and I've been running 5W30 since it was new. The oil changes are below. I live in Tucson, AZ and the lowest temp it gets outside is 30 degrees. And well over 100 degrees in the summer. Could I run Mobil 1 10W30 and be fine? Will it really make a difference between 5W30, or not? Thanks in advance.

10K miles Mobil 1 SS and filter
 
You could run 10W-30, but I doubt you'll see much difference, if any. You could easily extend your drain intervals with either oil too. I've been running my 3.4L 7K-10K with good results. There are quite a few used oil anaylsis results for this engine in that section. Look them over...

His best choice (if sticking with M1) might be to add a quart of 15w50 to that mixture, at least during the hot summer.
 
Since you have the 6 I would opt for the 10-30.

I mix about 200 ml of 15-50 M1 in the 4-Runner which holds 4.8 - 5 quarts.

My Taco just gets the 5-30.

I've been running 5w-30 Amsoil for the past year in my 01 Tacoma 3.4 for the last year here in Las Vegas. I am switching to 10w-30 Mobil 1 this weekend.....
 
10w-30. There is no need to try to thicken the oil for the Toyota 3.4 V6.
