I'd stick to what the manufacture says for your climate/location....I'd run the 5-30 synthetic such as R/P hps or Mobil 1 w/ a synthetic filter.....

In the Brutally Cold Canadian Winter™ where temperatures drop below -15C (5F), and often don't rise above -10C (14F), 0W-30 will definitely be easier on your engine (even with an engine block heater).

Otherwise, I use 10W-30 when the temps come up to (and stay up) above 0C.

Additionally, I run regular motor oil in my engine for the first 25000ish km (16000ish mi) on the odometer. After that, it's full-synthetic.

That's my opinion on the matter anyways.

There is no real good reason to use dino oil except for when the engine is brand spanking new and you want to speed up the break-in process. I am amazed that they have not outlawed this oil.

#1 It takes away fuel economy, negating any savings.
#2 You have to change it more often.
#3 It causes more wear and tear on the engine.
#4 Over time it messes up engine seals.

You are better off running synthetic oil from day 1 and keeping synthetic oil in for the duration of keeping the vehicle. And reap the benefits of extended drain intervals and reducing the need for oil and using up natural resources.

Just changed it @ 4000km (2485mi), and still going to change it regularly every 8000km (5000mi). I would never run more than 8000km on regular oil, it's just that I've come to know that running regular oil is a good idea during the break-in period.

LOL, you don't have to run syn oil at all if you don't want. I run cheap Walmart Supertech conventional ($2.78/qt.) at 9K OCIs and can't kill the cars, 3 now well over 200K miles apiece each and run fine. 10-40 in all of them right now.

The oil price totally smashes any fuel savings to atoms. They of course won't tell you that part.

If you're in Texas, I'd believe it. In as hot a weather as you guys get, you can run straight-weights. Even if you didn't, the additives in multi-weight oils probably wouldn't get much of a chance to break down and turn into acid in the 50C (~120F) temps you have down there, synthetic or regular oil.

Up here you simply have to run multi-weight oil. Our temp scale is -40C to +38C (-40F to +100F) depending on the season. This recent oil change cost me $46 CAD ($34 USD) for regular motor oil, which is a bargain in my community.

Yes, the cold there is a problem that oil has to be picked for. Here I had no problem even starting straight 30 weight at 5 below but that ain't spit for a low. When I used to straight weight I ran 40 in summer and 30 in winter.

The no 'global warming thing' up north has created more trouble anyway. Hotter temps often in NYC than here in Dallas, it's just crazy.

I would NEVER run conventional oil at 9k miles. I use synthetic oil and change my oil every 15,000 miles. You never saw that van that went close to 1,000,000 miles changing his oil every 35,000 miles with Amsoil? I have to find the story on that. They opened up the engine at over 900,000 miles and the entire engine was within 1% of factory specifications. Virtually no wear with all those miles. I've had plenty of friends over the years blow engines using conventional oil. NOT ONCE have I ever had anyone I ever spoke to ever blow an engine using Amsoil and their extended drains.

Since the Forum is preventing me from PMing a Seller in buy-sell-trade, because I don't have enough posts, until I spam the Forum with useless post:

Just let me say: "Wow. Confusing & informative." 0 weights seem to be popular to try now, online, but I'm not sure you hear, when someone has an engine failure, becuase of it.

Woot! That's #7!
