Maybe if there were some contributing intellectual thoughts and team discussions there wouldn’t be a need to keep visiting the topic. As a retired Principal Engineer and Project Manger most of the posters here wouldn’t make a year with me. Give me 5 why’s, why your using the engine oil in your car?
For being a "Principal Engineer" AND Project Manger" you sure type and sound like an idiot. Also, can't use the correct form of "your" or "you're."

Curious what a "Project Manger" is? Is this the person in charge of baby Jesus? Damn, you really ARE important!!

You sound more like a retired, self-absorbed moron.

Not one can answer the 5 why’s
I have five whys for you:

1. Why are you here bumping three year old oil threads instead of just one?
2. Why are you here in general?
3. Why do you think you are superior to other people?
4. Why are you telling people they aren't adding value while you do #1-3 above?
5. Why are you acting like a spoiled child?

OHHHH OHHHHH OOOOHHH LET ME TRY!!! LET ME TRY!!

1. I like oil
2. I like oil that does oil things
3. I like thicker oil because it takes longer to become thin
4. I've learned if I bleed out my vital fluids, I die. I consider myself being very close to a combustion engine, therefore blood = oil = living engine
5. It ain't none of my business
Actually not a bad start.
1. I like the oil it’s a name brand with tons of R&D.
2. The engine likes the oil as there are no vibrations or unexpected mechanical sounds throughout the rpm range.
3. Little to no oil consumption over xxx miles
4. The heavier weight and additive package is adequate as there is no excessive wear metals in the oil and thus are providing the right amount of oil

Quite Good! I have expanded on your thoughts

1. I choose the brand because they have tons of R&D.
2. Like my blood the fluid of life, the engine runs well with this oil. There are no vibrations, unexpected mechanical sounds, or leaks.
3. The oil weight and additive package cushions the bearings at operating temperature, like the blood in my knees do when walking.
4. Like my blood, the engine oil doesn’t thin out at higher temperatures resulting in excessive bearing wear and knocking or worn knees.
5. Like my blood the oil carries the contaminates for filtering.
6. Like my blood, the oil is adequately lubricating and transferring the heat from the cylinder walls and bearings as there is no oil temperature increase and thus no additional friction is associated with this oil.
7. Like my blood this oil is shear stable and long lasting resulting in acceptable OCI that meet my needs.

I am for technical information and sharing. Saying nasty words or posting stupid pictures isn’t contributing!
Are you wanting to control what I post and the questions i ask.
How is asking questions and sharing thoughts acting like a spoiled child or know it all. If I knew it all I wouldn’t be posting asking questions.
It is becoming clear some posters here like yourself just post nonsense. What have you contributed to the forum today?

Thanks for adding that in. The LSPI resulted in the reduction of the Calcium (a detergent) in the oil.

I would stick with the TOYOTA recommended SN grade oil and stay away from SP grade oils unless they are backwards compatible with SN and SL oils. SN+ oil was an interim grade oil while SP was written and tested.

SP was written to address LSPI , SAP’s, which destroy the catalytic converters and clog the particulate filters in the exhaust. Supra’s in the USA do not have particulate exhaust filters. And timing chain wear because car manufacturers don’t want to update the material, double row the chain, or modify the lubrication process. Sounds like the GM 6.2L disaster. Just change the oil and don’t address the root cause of bad engineering.

While SP grade oils have 1% or less SAP’s the SP grade oils also have significantly reduced amounts the critical anti wear additives zinc and phosphorus. Also responsible for rendering catalytic converters non- functional. From the few VOA’s I have looked at there is a 10-20% reduction in these anti-wear additives. It also appears some manufactures are adding more Boron into the oils to make up for the lower ZN and PO. I am in the process of understanding the increase of Boron in the oil.

Again, I would stay away from SP oils unless they are specifically labeled SP, SN+, SN and even SL. Or have a VOA in hand to compare to the SN grade.

Bro you already copy-pasta’d that in another thread. Hahah this is pure comedy.
