It is too expensive and that’s one of the main hindering factor running 0w40. I usually buy 30 gallon tanks from overstock sales. I managed to get 0w40 once and qualitatively felt better than 0w20 or 5w30
My 2013 has close to 278k miles, engine being smooth at that mileage makes one believe may...
Doesn’t see -40F, but those are extreme weather performance parameters.
0W40 felt right when I tow or cold mornings (here in Austin or when we visited NY during winter)
Cold weather protection but higher
I am quoting an online source “0W-40 oil flow can normally go down to -40℃, whereas 5W-30 oil flow can go down to -35℃. When it gets hot, 0W-40 oil shows better performance than 5W-30, with the ability to perform well up to +40℃. 5W-30 motor oil only flows...
Without too much technical know-how my experience with 5w30 has been very good. But I must say that few times we had freezing temp in Austin this year, the engine ticked more during cold start. But those days are very few for us here.
The smoothness of 5w30 is very very noticeable.
High performance German cars use 0w40 especially the BMW M series. 0 is chosen for the same reason (EPA), but smaller forced induced engines get more hot than naturally aspirated V8s, that’s why the 40 index is chosen.
0w20 works but 5w30 makes the engine sound extremely smooth.
The manual (US version) says that 5w30 is recommended while towing but if 5w30 is used then for next oil change use 0w20.
I have been using 5w30 for the last two oil changes, after the 2nd oil change the engine has been smoother than...
I alternate between 5w30 and 0w20. I use AMSOIL oil and TRD oil filter.
when running 5w30 the engine is noticeably smoother and quieter. Also helps when I tow 6000 lbs long distances.
