Drink a quart of Z rod Amsoil and call me in the morning.

Many oils use Moly as the heavy lifter for wear, while others prefer to use P and Z to achieve it. There is no one way to get to a reasonable Add Package. And You can have too much of an ingredient.....P and Z will foul the plug electrode at high levels even though those levels are best for the valvetrain. Just keep in mind that MORE of something isn't an indicator of better, there is a lot at play.

I agree with you on that. You really shouldn't be consuming any oil let alone enough to foul plugs but there is always a little vapor in the system. A cheap and easy way to help limit that is by installing a catch can. Mine catches mostly water but there is definitely oil mixed in there between oil changes.

Having a lot of a chemical causing issues was my thinking as well but I'm no chemist.

Here are my two favorite places to look at oils.
If you want to see element analysis, NOACK, cold cranking viscosity, ect. Use this link: http://pqiamerica.com/PCMO_Sample_Summary_12_15_2016.html
If you want to see how the oil performs use this link: 540 RAT - Tech Facts, NOT Myths
The Rat oil test site also has a Questions & Answers section were you can ask the guy specific questions and get a answer. He's a Mechanical Engineer by trade. Link is here: Q and A | 540 RAT - Tech Facts, NOT Myths

Got home from work and Amazon had a nice little package waiting for me, got my OEM aluminum oil filter housing in and it looks to be a very good part. I think this is a nice addition. Can anyone tell me about the center tube? Is the one on the aluminum housing the same as the one in our plastic housing?

You'll have to swap the center tube over from your OEM plastic one. They pop right out, no effort at all. I ordered one for my 2019 Highlander since I am getting close to 2K miles so the first oil change will be done in the next couple weeks. Curious to see what center tube is used on that housing.

Thanks man I appreciate the information, I can’t wait to do my first oil change just rolled over 1000 miles LOL.. The center tube looks to be good quality on the aluminum housing but I have nothing to compare it to. It looks to be made of aluminum.

Your OEM tube in the plastic housing looks identical but maybe an inch longer? I don't honestly remember, it's been 2.5 years since I swapped mine over.

I extracted a summary of RAT's oil testing from his lengthy and verbose report. He measured wear protection in psi, however he didn't measure Moly, Mag, Zinc and Phos content, so I included Moly and Mag content from PQIA. Higher psi values equate to better wear protection. Over 120,000 psi is fantastic wear protection. 105,000 to 120,000 psi is incredible wear protection. 90,000 to 105,000 psi is outstanding. One may argue that laboratory measurement of wear protection does not simulate how an actual engine wears.
RAT tested Amsoil oils Fall, 2017.
0W20 Amsoil Signature Series, no API designation, synthetic 134,860 psi at 230F. Onset of Thermal Breakdown not specified. Moly and Mag not measured for 0W20. Values for 5W30 are Moly 153 ppm and Mag 19 ppm.
RAT tested the following oils Spring, 2016. These are listed from highest to lowest wear protection (psi).
1. 0W20 Quaker State Ultimate Durability, API SN, synthetic (gold bottle) 124,393 psi at 230F (106,163 psi at 275F). Onset of Thermal Breakdown 270F. Moly 249 ppm. Mag 9 ppm.
2. 0W20 Toyota Motor Oil, API SN, synthetic 101,460 psi at 230F. Onset of Thermal Breakdown 255F. Moly 787 ppm. Mag 674 ppm.
3. 0W20 Mobil 1 Extended Performance, API SN, dexos 1 approved, synthetic 100,229 psi at 230F. Onset of Thermal Breakdown 265F. Moly 85 ppm. Mag 777 ppm.
4. 0W20 Pennzoil Platinum, Pure Plus Technology, made from Natural Gas, API SN, synthetic (silver bottle with blue vertical stripe on the label) 92,504 psi at 230F. Onset of Thermal Breakdown 275F. Moly 57 ppm. Mag 8 ppm.
Toyota Motor Oil has the highest combined Moly and Mag content and the lowest temperature at the onset of thermal breakdown.

That’s a nice sum up of the top five 0w20 oils, interestingly the top 3 are my favorite choices for the Toyota 4.0. Amsoil, QSUD and Toyota all look fantastic to me.
What oil are you running in your rig?

Quaker State Ultimate Durability 0W20

You could take 2 brand new 4Rs and run Walmart Super Tech 0W-20 in one and the most elegant boutique 0W-20 out there in the other and 15-20 years later, both would most likely still be running and performing about the same, moly/mag or no moly/mag.

Yes, Moly content levels are no indicator of the oil's quality or wear results as none of these additives should be in play until metal to metal contact happens through heavy lugging or rod stretching RPMs! Long term tests where engines were run on a dyno for thousands of hours to compare synth and dino in the same grade showed little to no advantage to the synth and in some cases a dino actually had less wear! If you don't exceed the normal parameters of an engine's operation you aren't going to exceed even the most basic approved oil's ability to work well.....changing it on a proper schedule is the bigger factor in longevity of the engine.

So, I've actually researched this considerably. Mobil1 is an inferior oil to some other big box store available synthetics, primarily Pennzoil Platinum. PP has a better additive package as per Blackstone Labs analysis. However, regular oil and filter changes will likely matter more than the particular oil you select, as you're not likely to keep the truck long enough to realize a difference.
As far as Toyota Synthetic 0w-20, apparently the formulation has changed recently, with a much higher magnesium content than it used to have. Long story short, the formulation is to help prevent pre-ignition in direct injection engines, and is a catch all for the entire fleet. It is not "bad" per se for non-DI engine, but it can lead to piston ring fouling in the long term, before a more standard blend oil.
Again, buy a quality oil and do the recommended changes and you're probably fine. I work with a guy with a 2015 Hyundai Santa Fe who hasn't changed the oil in something like 40k miles. We pulled the dipstick a while back and it was smoked out brown and mostly dry. A little bit of black oil on the tip. We joked about it a little bit, and he went to 7-11 and got a quart of cheapo store oil, and poured it in. He still drives it into work, and it is about 4 months later.

That QSUD is the best Off The Shelf oil on the marked right now! How many miles do you run it?

Tell us more about the new 0W-20 formulation when used in the 5th Gen 4R non-DI engine. How does this oil cause more piston ring fouling?

My apologies, Toyota has very high Moly content, not magnesium. I misspoke, as I'm not really an expert, but I did read a lot on the subject. I'll look for some references and drop them here when I find them.

10,000 mixed city (~75%) and highway (~25%) miles. Quaker State Ultimate Durability is about twice as expensive as Walmart SuperTech and about half as expensive as Amsoil Signature Series. SuperTech is branded to Walmart by the lowest bidder, so I choose to not buy it. What's the thermal breakdown temperature of SuperTech? I don't know. QSUD oil costs me about 0.4 cents per mile. Gasoline costs about 15 cents a mile. I choose not to buy Amsoil, which is the most expensive and arguably the absolute best oil. QSUD is a high quality (or very high quality) oil at a midway price point which makes it my preferred choice.
