2014 Tundra 5.7L w/amsoil Bypass filter 15,000km UOA

[zpinch]

Here is the first UOA I have done on my work truck that is used everyday towing a heavy 8000lb eaves-trough trailer with aerodynamics of a fridge with saddle bags, I also live in Saskatchewan Canada, many gravel roads I have to run to get to jobs. Averaging 23L/100km fuel mileage, so pretty high daily engine load.

Other engine related add-ons are obviously the amsoil dual remote bypass filter, EA-BP100 & EAO26 full flow (heavy filtering!). I also installed at the start of this oil change interval an Injen nano-dry cold air intake, I feel it's a good idea in my situation.

I did add a product called AW-10 anti-wear, 200mL per 10L engine oil.

Total system capacity is 10 liters.

What is it you believe the AW-10 antiwear will do during your OCI?

looks grat
keep doing whatever you're doing

Looks better than my 2019 Tundra pavement princess whose only job is hauling me around.

Isn't the bypass theoretically hiding wear? Yes it's filtering out wear metals and stopping them from flowing all around the engine. But in the case of a UOA wouldn't that mean wear would potentially appear lower than it really is?

I don't believe anything, I use their other products with great results (Cost Effective Maintenance) including CleanPower in the gas, and RMI-25 in the cooling system to prevent the Toyota water pump failure. The upper cylinders are super clean and the CleanPower acts as an upper cylinder lubricant.

All I can say for the AW-10 is it makes a very noticable difference in engine noise, it seems to hush it right up, nice and quiet. Does lower noise mean lower wear...??

I'm not sure where you heard that it filters wear metals, it doesn't, they are much smaller than a bypass can capture.

It filters any contaminant out, sludge precursers, and essentially keeps the oil cleaner than new oil all the time.

looks like fantastic wear given your severe service uses. even silicon is low, which given all the gravel driving you do, looks like the air filter is also working great. keep on keeping on!

Good results on a working 0w-20

Back when Tundras had a great engine.

I am very happy with the results of what I'm doing.

I also changed the full flow EAO26 filter and left on the BP100 filter (actually I drained the old oil out by pushing gently on the anti drain back valve while holding it upside down.

Pennz Ultra Plat out, Amsoil SS 0w20 in.

I will post some pics of the setup here and on the bypass filter section.

Wish it was still an option or Toyota would enter the diesel market in the states

well, truth be told, we really don't know how good or not so good it will be, yet. The engine recall is a manufacturing ****-up, and nothing to do with the design. Maybe it will turn out to be a rock solid legend like the 5.7L and even better, the 2UZ 4.7L before it, better than the 3UR.

Personally I don't think it will be AS GOOD as the 3UR, for the simple fact it is smaller and has twin turbos with multiple cooling systems...

I am going to take care of this baby and I will just live with the lower than average fuel mileage.

Thanks for the post!
It's Great to see you running the Amsoil Dual Bypass filter system on your Toyota with the EA-BP100 & EAO26 filters. I've been running that exact setup on my 2011 Expedition EL 4x4 King Ranch for almost 9 yrs, and almost 300k miles.
That system has served me well. You're UOA looks good, and you've got a lot of TBN left to increase your OCI's by 30-50%.
If you don't already have a petcock, I would recommend that you install one. They are quite useful for sampling, etc
Here's a pic of my setup with petcock
I look fwd to following your results
