I roadtrip often to the Sierras and colder climates (nothing THAT cold right now) but during the winter I would see temps in the low 20sYou said you are in South California, thus a 5w-30 will be fine.
So a 30 grade would have better HT HS properties right>?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.
@chriscosta416 do you have any data based justification for switching?
It seems the 0w-20 has worked well to this point.
So the answer to my question is 'No'.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
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?So the answer to my question is 'No'.

Personally I find that unacceptable. Sure maybe in a new Toyota engine since the company has started declining, but I don’t lose any oil level on my dipstick at all in my 2001 Toyota tundra 4.7…. That’s because that’s when Toyota made perfection. Can’t say the same with their new age engines. Losing half a quart from evaporation is laughable especially below 4k miles. That doesn’t happenYou'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.

Yes some guy in this thread is saying he lost a half quart in 3500 miles and members here are saying that’s normal due to evaporation lolHalf a quart from evaporation?
