    I changed oil to a 0W30
    In short it's better, but advantages occur under conditions that don't occur 12 months a year
    The north country zero and below is common wile 5 w 30 works well any way .
    0W30 starts motor even better & even feels smoother ( if it's even possible )
    So for cold starting 5W30 is fine ....... 0W30 is king .
    I found with MPG
    My Tacoma gets great MPG on the HWY I can pull from 27 to 28.8 depending on how relaxed I drive
    If I go 55 to 60 I will get 28.8 fully warmed up 0w30 or 5w30 same MPG
    Short trip cold weather 0 W 30 blows 5w30 out the door
    during the summer I'll put in $20 & drive all over (many miles)
    at one point I say heck I drove alot for $20 ,that is during the summer
    As the winter cool rolled in I was noticing Gas MPG was BAD like $10 per day I had a hunch
    and the hunch was short trip cold so I excepted it .( thats winter I figured ) .
    Now with 0W30 I put in $20 and getting that same MPG as summer I'm at day 3 still have plenty of fuel
    0W30 is fantastic for short trip cold weather use .
    Most likely this will be the oil I use year round
    unless I notice an issue during summer
    So till further notice Mobil one 0 w 30 is my oil

    Isn't 0W20 specified?

    It is on the 18 I just picked up last week. Don't know why it'd be different for 16 or 17.

    What you are stating.
    The 2016 and 2017 Tacoma manufactures suggestion for OEM oil is 5w30 and the 2018 with the same engine is 0w20?
    What’s up with that?

    Beats me. That's what the 2018 says to feed it with. Didn't know 16 and 17 were different...

    Maybe it's a regional thing? I'm in Southern Idaho... 20171228_153255.jpg

    2008 calls for 5w30 and 0w30 - meets that spec at the most important area ,normal warmed up running conditions as 30 weight
    at start up running zero weight has to lend to less motor wear & it is a 30 weight when needed
    If 2018 calls for 0W20 ,it's the 20 weight aspect you have to wonder about If Toyota tightened up the tolerances then a 20 weight is needed
    it's said the engineers do the test's - invest the money .& what they recommend is best .
    The real news of requiring a 0 w 20 is auto manufactures have crossed the divide
    Zero weights are best gracefully formulated with synthetic
    or at least synthetic blend , conventional oil is being replaced
    this is just the beginning
    future oil requirements are heading
    for 0 w 16 and even 0w8
    I suspect some day maybe in 10 years , mentioning synthetic will not be necessary as it will just be the Norm & The only way to make it for the application
    But the future will be listed as the term GROUP and a higher
    group number, equals a more refined base stock .
    Group 4 as well as 5 is a pure synthetic
    and anything below that is truly not a synthetic oil,
    but Group 3 Base oils are allowed to be called synthetic

    IMO if it calls for 0w20 use it
    hot weather 5w20 would logically be ok

    If anyone lives in southern Missouri, I get synthetic 0w20 for free. Only 2-3 gallons of leftovers at a time when I haul it.

    As best I can tell, the 4.0 specified 5W-30, the 3.5 specifies 0W-20. For what it is worth, the 5.7 in the Tundra specified 0W-20 from its intro in 2007.

    My 2007 Tundra took 0w20

    Well I can't stress this to much it's around zero and 12 degree highs . My short trip Gas Mileage is fantastic What I suspect now is
    trips of 10 to 15 miles in winter is short trip as engine is warmed up proper after 10 to 15 miles till it is warmed up nice a five weight has more resistance then zero weight
    I can't see how in summer a zero weight will add any fuel MPG gain
    but who knows For sure Mobile One 0w30 is no snake oil

    Well a warm spell and just about 60 compared to last weeks below zero .
    0W30 is fast becoming the only oil ill ever use , smooth as silk I gotta say
    Holy Crap is the 4.0 smooth
