You know some part of Canada regularly get 100+°F in the summer? I would say unless you live in the middle East, where temps stay 100+ at night, you don't need heavy weight oil. Sent from my A0001 using Tapatalk |

Phoenix gets to 120 in the summer. Stop and go driving with the AC on under those conditions would be about the most extreme operating conditions I could imagine. I definitely would want some input from people with professional experience about what oil to use. I have serious doubts 5W-30 is going to cut it.

I take either my 2010 Yaris or my 2012 Honda Civic. I was concerned because Honda only recommends a 0W20 oil for the Civic. So I E-Mailed Mobil 1 back in 2013 about my concern, their response; Dear Bill, Thank you for your inquiry. Mobil 1 0W20 AFE does provide excellent high temperature protection and thermal stability is outstanding. It is certainly fine to use Mobil 1 0W20 in the environment that you described. According to the specifications for your vehicle, 0W20 is recommended and we highly recommend that you stay with your manufacturer's requirement. Sincerely, Mobil Help Desk 1-800-ASK-MOBIL Well, if Mobil 1 0W20 AFE (what I use in the Honda) can handle Phoenix and Las Vegas temperatures, can't I assume that Mobil 1 5W30 EP (what I use in the Yaris) can also handle those extremes.

However! When your car hits 100k miles and you put 0W-20 (or even 5W-30) synthetic oil in it the oil consumption is going to go UP! Even more when its 120 degrees! My wifes Camry with ~120k uses a quart of 5W-30 (regular) in less than 2000 miles but only about half a quart of 10W-40 in ~5000 miles. Since synthetic oil is thinner I have to believe oil consumption would be even higher in that case. If you have children like I do when they come to visit theres often no oil on the dipstick and 15 psi in the tires. Having been a car mechanic Im pretty sure the general public isn't to far from those things too.

My blue Yaris = 'Phoenix Summer Weather Tested' , so to speak. Lots of stop and go as well. Also, have never done a cooling system flush on the '07 either......and I've never had any Yaris issues in Phoenix and always = running 5-30 oil.. That heat though.........usually one of the only places in the U.S. that regularly has a summer heat index that exceeds any of the major Texas metros. One of my cousins lived within the Phoenix Metro for 10 years....and at certain times during the summer....he'd go to Prescott to escape that level of heat. AFAIK, my cousin always used the recommended in the OM oil weight for any vehicle (subcompacts), usually 5-30.
