    Have always used 0w/20 Mobil 1 since day one in my 2014 5.7 , thinking of switching to 0w/30 for a trip pulling heavy boat to lake Powell from central AZ. Owners manual states "an oil with higher viscosity may be better suited if the vehicle is operated at high speeds or under extreme load conditions". Does anyone have experience good or bad switch oil weights?

    There's no downside to what you are looking at doing. Maybe not needed but would not hurt anything

    I'm thinking you might lose a little mpg under similar driving conditions

    0W30 is a great option for towing at freeway speeds, high heat situations. I used the hell out of it every spring to fall.

    Shouldn't be an issue either as long as it meets our manufactures specs for engine oil.

    well spec is 0W-20 but the 20 is what gets me since with dino xW-30 or even xW-40 used to be recommended (not for tundra ... at least in US) for hot weathers.
    I need to study the synthetic oil and see what 20 means relative to dino 30 or 40 ...
    never used synthetic before and I have or had cars with 270K miles and one with 400K miles using dino 10W-30, 5W-30 and 10W-40

    I've seen some guys who two heavy using 0w-30. I personally would go with 0w-30 rather than 5w-30 even though the difference between 5 and 0 is small. Cold start doesn't mean cold temperature start.

    0w-30 maybe a good alternative for hotter climate or towing ...

    fyi, they sell the same Tundra and sequoia in some counties that don't even have synthetic.
    I was talking to an army guy a while back and if I recall correctly he told me that Toyota specifies 5w-30 dino in those countries.
    he also mentioned something about xW-40 but I don't remember.
    I don't think Toyota changed the engine for US market!

    we have a 2014 car that specifies synthetic and also 5W-30 or 10W-30 if synthetic is not available!!!!

    0W20 was used for fuel economy. For towing, use 0W30.

    I'm not towing but my truck sure as hell weighs almost a ton more than stock, especially with the 40" tires causing more drivetrain stress. Should I switch to 0W-30 from 0W-20? I'm in CA for weather.

    I would be the last person to definitely recommend something different than the manufacturer spec (0W-20).
    having said that, in US alone, the 0W-20 is specified for a wide temp range from Alaska (-40F or colder in winter) down to Phoenix area (wasn't it 120F a few days ago) ... also 0W-20 suppose to cover one year and/or10K miles. So we are talking about a wide temperature range.

    • would 0W-30 be a better choice if towing in hot weather or if you live in Phoenix or southern states???
    • Can a knowledgeable person tweak the spec (e.g. use 0w-30) based on the region & conditions they are driving in?
    • What does Toyota recommend for the same engines in Europe, Africa or middle east or other parts of the world with cold weather? Based on what i have heard, some don't have synthetic yet and Toyota doesn't specifies it either! we need to get hold of a foreign user's manual! I was told spec is 5W-30 (one of my favorite dino oil) is some of those countries.
    now what?
    1. its a good idea to study synthetic oil and make an educated decision. refer to bullet #3 above!
    2. even better is to do a UOA (Used oil analysis).
    0W-20 maybe a cure-all. like I said before, I have never used synthetic and Tundra is my only car that specifies 0W-20 and I am not due for an oil change yet. btw, I have heard rumors (even mentioned on this site) that some dealers don't have 0W-20 and use bulk 5W-30.

    the above is on my to-do list, amongst millions of other things .... lol
    I am very comfortable with dino oil, I have/had cars with over 187K, 270K and 400K miles with no engine problems using dino oil. also previously mentioned that we have a 2014 car that specifies synthetic and also 5W-30 or 10W-30 (my other favorite oil) if synthetic is not available!!!!
    Synthetic is a new territory for me. I ask questions to see what others have experienced and what oil they are using. I know one of my neighbors with a 2010? (can't remember) Tundra who uses 5W-30. He is an older guy and anti synthetic! his car runs great! again I am not recommending it.

    conclusion:
    until I do my homework (refer to 1 & 2 above), I will use 0W-20.
    would I use 0W-30 if I had to? yes
