    Update: 5W-30 & Heavier Recommended RoTW

    Yep, a number of us have. 12180-38030 Fancy blue “F” series writing too.

    The noisy valvetrain I reference is quite subjective.. somewhere between a quiet hum for some people and “we need to adjust those valves, now” to other ears. It’s a very common quirk of the 3UR and nearly everyone that switches to the thicker oil reports it getting quieter. Which isn’t to say...

    It’s good to confirm nothing went wrong but you’d really need much more data over longer intervals to truly compare their efficacy. Which should be a surprise to no one. Personally 5w-30 made my valvetrain sound happier at all times and I haven’t had a single occurrence of the timing chain...

    And all of these oils, changed often enough, addressing other things like radiator and valley plate or even cam tensioners/phasers, will see our engines past 400k if you can afford to keep putting fuel into it. Toyotas are well-known for being easy on the oil.

    The front main seal, oil filter stand and cooler gaskets, valve cover & spark plug tube gaskets would like to have a word. But I agree with @Artie one oil change with the stuff isn't worth dumping it.

    I would never run “high mileage” oil in an engine I intend to keep. The seal swellers they often add will reduce rubber density & stiffness and lead to them wearing more quickly. Also I admit this is opinion, but 156k isn’t at all high mileage for a well-maintained 3UR

    Mine has had sporadic cam tensioner issues in the past despite 5k OCI from new, other than the 8k and 7500 that I experimented with a couple years ago. IMO the cam tensioner issue is more a design issue than extended OCIs, though I agree those would make it worse. While I agree with your...

    I think it depends on the engine and oil used though. My second TDI VW had 10k OCI using M1 TDT from new, 270k miles on it when I got it, and under the valve cover you'd think it was a new engine. I sold it to a friend at 360k, they drove it to 450k before selling, and to my knowledge it is...

    TBN isn't the whole story, though blackstone would know that. I know on my rig if I go past around 7500 miles on a change oil consumption goes from practically zero to.. not. There is a marked uptick. I don't know if that's some function of a viscosity threshold, fuel dilution, or what.. but...

    All US 200-series 5.7s came with the "towing package" engine oil cooler. I'm assuming some Tundras did not. Looks like the dipstick differences only apply to before 2013 200s Dipstick 09/2007 - 06/2009 15301-38060 07/2009 - 04/2012 15301-38061 06/2012 - 2021 all the same 15301-38062 Similar...

    Update: 5W-30 & Heavier Recommended RoTW

    Genuine Toyota = $21, AEM = $70. At the recommended interval plus the original this would bring you to 150k miles before costing more than the AEM. All while getting better filtration. More pleats than Genuine Toyota? The gasket does seem to be an issue on the original filter, but that's...

    Update: 5W-30 & Heavier Recommended RoTW

    @AnyMal my understanding is they have to use different and more involved additive packages to accomplish a wide viscosity spread, and the issue may be the stability of that additive pack over the oil change interval. Whereas if the viscosity spread is narrower you are depending more on the...

    Update: 5W-30 & Heavier Recommended RoTW

    A given vehicle can have vastly different oil temps depending on what the operator is doing with it, let alone how different vehicles can cool (or not) the oil with various methods of doing so. I bring this up simply to say “works to +35 or +40” is a huge oversimplification. It depends on the...

    5-30 year round for me. Winter in Alaska/Canada/Montana etc would be a different story, even though realistically that would be fine too. I’d probably push for 0w-30 there.

    For everyone’s info the fill cap gasket is replaceable separate from the cap. Puncture the old one with an oring pick and pull it out. Fresh soft rubber makes a huge difference in how progressively the cap tightens.. vs just turn turn *stop* 90430-35001 For the replacement gasket.

    "Energy Conserving" on a 200-series is particularly funny.. I'm definitely ordering one.

    @TeCKis300 strongly advocates this type of oil, and I see no problems with it. I prefer 5-30 simply because that is what I’ve been running already and it’s a bit easier to find.. but I may consider 0-30 for winter months in the future.

    On the contrary, I don’t see the point in not using what they specced for the rest of the world, including some of the harshest environments in which these vehicles are used. Not to tell you what to run..
