5w-30

[DENNISD]

Changed out the factory fill at 5k miles, at 27k miles… so far, so good….5W30 Napa Synthetic for the past 22k miles

Why would it not be okay? Heck, you could easily run a thicker oil and be fine with those low of miles.

Unless you are driving in hot conditions or pulling/hauling heavy loads, you are simply not getting the mileage that you could be getting running with a thinner oil.

It is as simple as that.

The only thing that I was pointing out earlier is to follow the owners manuals. The people on this forum that think they know better are guessing at best.

This wasnt meant to be whether you believe what American Manufactures handcuffed by CAFE standards are feeding you. The same manufactures that told you 10k oil changes. The same ones that recommend a 30w overseas.

There's vids posted on this thread that show how much better a 30w protects against friction vs a 20w. There's also lots of peeps showing how their 20w is being diluted by fuel which would lower the viscosity even lower then the 20w you think is running in your engines.

I remember sitting in a class with those same engineers and them telling us how the new Tacoma (3rd gen) is designed to run at high rpm's to get horsepower out of the engine. Same as that Toyota engineer that replied to TFL axle fiasco that its designed to self destruct where a subaru could of made it.

Instead this thread was meant to be for peeps running a 30w and sharing info and oil analysis. We'll make up our own minds after we see the engine wear, and not what some jackass wrote in a manual because the Govt forced him to.

22k miles of using 5w30 and … so far, so good

I think if you stick to it OCI 5K miles that taco will make it to 200K miles plus.
5W30 seems to be the right combo. All ford trucks new and old are on 5W30.
You hear Fords being trash talk about cause it’s due to customer neglect and that’s any brand, any vehicle..

Perfect example is the vid i posted earlier of the dude doing his 20k 4th gen review. Good Guy, good vid however he starts the vid off with why everyone needs to use 0-20. Then when he posts his oil analysis and its showing increased engine wear he blames it on "maybe his tires" Instead of the absolute most obvious. The oil he's using is not protecting the engine sufficiently.

So its not about what someone wrote or thinks, it needs to be validated by oil analysis's. So no matter what oil your using post them up and lets figure it as a community.

I think oil analysis is useful, but we still have to be careful about drawing conclusions from a single report.


There are a lot of variables that can influence wear metals in a sample — driving style, trip length, engine load, fuel dilution, ambient temperature, dust, and even the sampling method itself. Because of that, it’s really hard to point to one result and say the viscosity was the cause.


To truly prove something like that you would need a controlled side-by-side test under identical conditions. Otherwise we’re mostly just interpreting trends.


Manufacturers like Toyota have already run thousands of hours of durability testing under many conditions before settling on the oil recommendations in the owner’s manual. While CAFE standards definitely influence the push toward thinner oils, the manufacturers also have to protect themselves from warranty claims. They wouldn’t recommend something that leads to widespread engine wear.


At the end of the day, most modern engines are very well engineered. Whether someone runs 0W-20 or goes slightly thicker, the engine will likely last a very long time. I think the bigger takeaway from oil analysis is simply making sure nothing abnormal is happening rather than trying to prove one viscosity is universally better than another.


Just my take on it.

Dennisid, the idea is too compile some real data so we can learn from it and make adjustments. Not just one, but lots of people thru the years. Like I mentioned earlier the Power Wagon peeps have way over 100 pages on one thread and they have the oil thing dialed in pretty good.

Granted most people buy a Toyota so they can dump in Mobile 1 drive for 200k miles. I get it and that why Toyota has such loyal customers. Its well deserved.

Now then, there's a handful of peeps who love to nerd out on their trucks and want to see the real numbers. That's what I hope to start going here.
