The winter rating is important for expected starting conditions. The difference in cranking and pumpability between a 5W and a 0W rating is apparent below -30 or so. Above that there is little to no difference, either one may be thicker or thinner. But as long as it can be pumped it will make it to needed engine areas.

Both are 30 grade oils however. HT/HS is a better indicator of protection at operating temperature.

So a 30 grade would have better HT HS properties right>?

@chriscosta416 do you have any data based justification for switching?
It seems the 0w-20 has worked well to this point.
I have been reading up on using the 5w-30 weight on ih8mud, Overseas Toyota calls for 5w30 and a wide range of weights for the 5.7. In the states it calls for 0w-20 and people are assuming its for CAFE standards. My truck is often loaded up with gear and either bashing through dunes or climbing rocks so I was thinking of switching to a heavier weight oil since my truck would fall under severe use per the owners manual.
I assume a slightly thicker oil would be better for a higher mileage motor as well as often better protection
So the answer to my question is 'No'.

There are probably 100 existing threads on this topic. Perhaps you should search around on the board a while before you ask a bunch of related questions?

You are correct, I have no solid data other than losing half a qt at 3,500 miles. Is it safe to assume a heavier oil would not evap/burn off?
You're chasing a problem that doesn't exist.
You burned a half a quart in 3500 miles on a vehicle with 173k+ miles on it.
That's fantastic performance.
There's nothing that needs to be fixed.
There is no problem.

And you may be interpreting that data wrongly. Losing a half a quart in 3500 miles is insignificant considering the age of this vehicle and the miles accumulated. You also don’t know the prior maintenance history.

Thanks for your help everyone, sounds like I was asking for an advice on something that is not an issue.

Regarding maintenance history, Lexus service records show oil changed every 5-7k miles since first owner. I am the 2nd.

I have run Pennzoil Platinum 5w30, Mobil 1 5w30, Amsoil SS 5w30 and current fill is Mobil 1 EP 5w30 in my 2011 Tundra with the 3URFE. Will be changing the oil again in the next month with M1EP 5w30.
