Welcome to BITOG. Thick vs thin and daily Amsoil threads.Telling us the car would help. It’s no use assuming one is better than the other.
Yes it is.My very simple logic here is the 5W-30 is probably the better choice for the engine. If 0W-20 was really what was optimal, why not recommend it globally?
Thoughts? Especially when it’s hot.
Because in many parts of the world 0W-20 is not readily available so the recommendation are changed based on what's available in the area, in like Mexico, Central America, the Carribean, Africa, and the Middle East, 20W-50 and 25W-60 until relatively recently (or possibly still) were all that were available, in Russia I think 10W-40 or 15W-40 are actually the most commonly available grades, In Europe C3 and A3 oils are among the most common so the manuals in those countries they recommend based on what's available.My very simple logic here is the 5W-30 is probably the better choice for the engine. If 0W-20 was really what was optimal, why not recommend it globally?

It'll make no difference. Automakers recommend what is optimal for your market. Optimal isn't viewed as a tradeoff between emissions vs engine wear. Availability and cost of lubricants as well as operating conditions (ex, autobahn) also play a factor.My very simple logic here is the 5W-30 is probably the better choice for the engine.

For the conscientious owner who chooses a quality synthetic oil and changes it frequently, that's likely quite true.It'll make no difference. Automakers recommend what is optimal for your market. Optimal isn't viewed as a tradeoff between emissions vs engine wear.
I towed a 5,000 pound travel trailer with a Silverado 5.3 running 0w/20 all over the Rocky Mountains and the motor didn't blow up.My very simple logic here is the 5W-30 is probably the better choice for the engine. If 0W-20 was really what was optimal, why not recommend it globally?

Blasphemy!! You must be a plant or a bot sent here by a secret society which wishes to make our lives inconvenient. Where's my aluminium foil.I towed a 5,000 pound travel trailer with a Silverado 5.3 running 0w/20 all over the Rocky Mountains and the motor didn't blow up.
According to BITOG, you just narrowly escaped catastrophe!I towed a 5,000 pound travel trailer with a Silverado 5.3 running 0w/20 all over the Rocky Mountains and the motor didn't blow up.
10W30 even better-er!My very simple logic here is the 5W-30 is probably the better choice for the engine. If 0W-20 was really what was optimal, why not recommend it globally?

I have the same preference as Astro14.Running either oil viscosity isn't going to affect your engine as long as you change it as required. Honestly, I run 5W30 in my Toyota, which specifies 0W20.
There is zero difference in MPG and it's way too soon to judge wear.
The 5W30 was just easier to find, and allows me to comply with that one sentence in the owner's manual that says a higher viscosity may provide better protection under heavy use like towing.
Don't sweat it either way.
