Easily 10w30
Does ambient temperature matter? The engine still operates within a specified range.I know Honda recommends OW-20 for the 1.5 Turbo engines in the Honda CRVs. Being located in Phoenix, AZ, where outside temps hit 115F and pavement temps exceed 140F+. Would it be okay to run a 5W-30 synthetic oil like Pennzoil Platinum or Valvoline? The OW-20 seems to thin for this type of climate.

I'd go Royal Purple 10-40. Had great results with my Mazda rx-7I know Honda recommends OW-20 for the 1.5 Turbo engines in the Honda CRVs.

Withstand it how? That would be some seriously low HT/HS. Not something I’d want in my engine.0w-20 could withstand temperatures of 400+
You neglected La Crème de la crèmeA few previous threads on this oft-asked question:
Hot ambient temps and engine oil question.
Why do people think or consider 100F ambient temp is hard on oil? Flows easier in the engine than colder temps. If engines run at 180-210F how can 100F ambient temprature be hard on the oil and be considered severe service?bobistheoilguy.comDoes ambient air temperature matter or not for Oil
I am greatly confused about one main thing: Air and climate temperature, vs grade of oil selected for a car. Please let me explain. In almost any pre-2001 car manual (and some after that) i see, i see charts of temperature vs grades listed for the engine. Most charts list 10W-40 from around 10...bobistheoilguy.comOil temperature versus ambient
It has finally cooled down up here in the GWN and so I got curious as to what the oil temperature on the Charger was. Warmer temps, in the low to mid teens, it was 98-100C (208-212F). Tonight, driving around the temperature varied from a high of -18 to a low of -20C (roughly -1F to -4F). Oil...bobistheoilguy.comOil Viscosity/Ambient Temperature Relationship
Okay, here's my question for you guys. I've always been interested in how it seems that there are discrepancies between what SAE grade of oil (once the oil is up to operating temperature) and the corresponding ambient temperature in which it should operate. For instance, comparing two Honda...bobistheoilguy.comGrades for high ambient temperature locations
Living in the greater Phoenix, Arizona area we have winter temperatures down to -4C/25F and summer temperatures above 43C/110F. There are days when it gets above 46C/115F. I'm convinced manufacturer's recommended grades of 5W20 or 5W30 are not appropriate at higher ambient temperatures. I...bobistheoilguy.comWhy does the high ambient temperature matter?
Since engines are liquid cooled and have a set operating temperature why does the upper ambient temperature matter when selecting an oil grade? I totally get the low ambient temp being important because the oil has to be able to flow at startup in a cold engine but the engine gets to 200+...bobistheoilguy.comAmbient temperature vs. engine temperature
I've read many posts on the forums advocating the use of higher viscosity oils in hot climates, say 10w-30 vs. 5w-30, or 10w-40 vs. 10w-30. What I don't get(and correct me if I'm wrong), is that it seems to me that the temperature inside of an engine in operation and at operating temperatures...bobistheoilguy.comOil Weight and Ambient Temperatures
I asked this before, but didnt get a straight answer. Whats the point of running a thicker running weight in extreme heat? We see here that (some) Australians and folks in the Middle East like a 50 or 60 weight oil. Wouldn't the radiator keep oil temperature somewhat in check and prevent any...bobistheoilguy.comThicker oil for hotter ambient temp, Why?
It's common for manufacturers to recommend thicker oil for higher ambient temperature. But if the coolant temperature gauge says the bike isn't running hotter, why different oil? Does the engine have hotter operating conditions in some way not indicated by coolant temperature? Or in the case of...bobistheoilguy.comHow does high ambient temperature affect oil ?
I see posts from people from Las Vegas and elsewhere thinking they need a better oil at > 100F ambients. If a vehicle is operated under similar conditions (normal driving), how does ambient temperature become an issue if any engine cooling system generally maintains a stable engine operating...bobistheoilguy.comDoes ambient air temp matter /that/ much for weight?
Living in AZ, this summer I expect to see my daytime highs no less than 105F or so with a few 115F+'s thrown in here an there until well into October. Now I traditionally have run M1 15-50 in my Toyota 1FZ-FE engine (~100k) and my Ford Probe 4cyl (~160k) during the summer months due to...bobistheoilguy.comAt operating temp, why does outside temp matter?
This is a bit of a noob question. Regarding an oil weight... Once and engine reaches and maintains its operating temperature, why would the outside, ambient temperature matter? Say in one case it's 70 degrees outside. Say in another it's 105 degrees. An owner's manual might spec a xW-30...bobistheoilguy.com

Royal Purple, great looking bottle, I have always wondered how long the Purple Color of the Oil stays Purple after you have driven it for a while.I'd go Royal Purple 10-40. Had great results with my Mazda rx-7
Heat exchangers do help, but they still don't regulate the oil temperature nearly as well as the coolant temperature is regulated. The oil/coolant heat exchanger on my Subaru keeps the oil temperature within 10°C of the coolant temperature in normal driving in normal weather, but it's still possible for it to get 30°C hotter than the coolant with hard driving in hot weather.Assuming the OP's vehicle uses an oil/coolant heat exchanger like most modern vehicles, the temperatures of oil and coolant are typically quite close together.

Is it 10 miles or 100 miles.
Yeah not all at the same time. Heat protection doesn’t mean simultaneous wear protection. Physics still matters.
I will just have to buy a quart of Royal Purple and get a Shot Glass and pour in the Oil and just leave it on my desk. I do have a Royal Purple Oil filter sitting on my Desk, nice Color.When I used RP about 15-20 years ago I recall that it didn’t even show up as purple on the dipstick when I checked it after idling the engine for 20-30 seconds after the oil change
I have to disagree here. In any sort of normal climates, what you say is true. I have an old dodge truck thatI put an oil temp gauge in years ago. While living in Phoenix, the oil temp absolutely rose higher in the summer than the winter; the water temp was on the high side of boiling, and the oil got HOT.Ambient temp means virtually nothing. What matters is oil temp.

Really. Another strange issue that’s trying to be mysteriously connected to the octane rating of the fuel.Will run the 5w-30 Valvoline synthetic and a Wix filter.
I know it's another topic all together but are the head gaskets an issue with the 1.5 turbo engine in the CRV?
I read running HIGHER OCTANE fuel (91) will help with potential head gasket issues.
Really? my "old Dodge Truck" running on gas and lubed with oil is somehow radically different from a newer car with a turbo yet? New car oil doesn't get hot, stays magically cool under all conditions? I think not.In what way does your old Dodge truck compare to the OP's modern vehicle?
