Sorry, here's the report.

A bit confused on which metals are purposely used to make engine oil and metals that are considered wear metals. The reference numbers for the 2grfe uoa are almost 7,000 miles and my oil only had about 4,300 on the it. Mine indicates 1 on tin, where the average 2grfe with almost double the miles...

Good good talk about OCD.

That's because the 09+ has the 2ar fe.

That 2.5 will probably run like a top until the coming with any old oil, my Toyota only mechanic compares it to the old 5sfe as far as robust design.

Actually with high ambient temps you're in an even better position, quick warm ups... which is easier on oil, little to no fuel dilution, ect.. when it's below freezing here I tend to try to combine my trips as to only have to warm the car up once a day, in the summer I don't pay attention since...

What do you mean by heat, internal combustion engines run in a very narrow temp , ambient temps aren't a factor.

That's about dumbest summation I've heard of, iron block aluminum heads are some of the longest lasting engines in the world, you totally ignore there's an engineered head gasket between them.

You just picked that out of nowhere , and you're confused.

Interesting, did you have any detonation caused by combustion chamber deposits caused by oil burning?

After all these years bitog members still referring to oil control rings as compression rings.

$200 or $2,000?! The 2azfe is is an expensive engine, I'm talking a few thousand, even with 100k miles, I don't get it.

It's supposed to, rings on non running engines aren't exerting why pressure on the cylinder walls.

From what I've gathered, Seafoam isn't as harsh as it contains some petroleum, b12 supposedly doesn't have any .

Pertaining to piston soaks I've concluded that this product is the most effective to dissolve hard carbon deposits on piston tops, but I remember reading somewhere on berryman's own site that it should not be used for more than a few hours due to coated aluminum being damaged by the soak, also...

Shows what I knew, I was under the impression that there newer synthetic/sealants were superior in the shine department, heck even my wife noticed the glowing paint and asked what I did to it🤪 I might just stick with good old fashioned carnuba.

I tried the "old fashioned" mother's carnauba wax -cleaner in the tin on my Toyota Barcelona red paint, and wow.. It gave it a nice deep warm glow. I've used many products over the years with, mainly the ones mentioned here but I don't remember ever getting this deep warm glow before, there's...

So 200k miles is "very early" in a little ice engine's life, nevermind being 18 years old?

Valve guides seals aren't a major source of oil burning, heck engines didn't even offer to have them. And when you say "rings" , oil control rings and compression rings serve two different purposes, oil control rings for instance have nothing to do with compression.

Except that oil thickens with usage.
