As long as there's a bottle sitting on the desk of the Toyota engineer who wrote the formula, it will provide superior wear protection under all circumstances, everywhere at the same time.
TGMO...it's what's NOT inside that makes it so special.
thanks Shannow!! I was dying laughing!!

Decided to finally get a UOA on one of my cars, a 1996 Honda Civic, 200k miles. Would like to get everyone's opinion on the results I just got back from Blackstone.. I'm thinking it looks good. But wondering about that Lead number, averages are 4, I'm at 5, no big deal? Or am I over thinking it about changing from 5w20 to 5w30?
Lead is a little high but then these old engines tend to show high lead. I don't know if switching to thicker oil would help.
I dislike oils that contain sodium because then you can't tell if there is coolant contamination, which also brings sodium. Coolant contamination would increase lead wear.
If you're going to use xW-20, use 0W-20 synthetic instead of 5W-20 conventional. It protects better.

yeah I can bet Lead was a little high because the oil was thinning out way too much. The engine was designed for 5w-30 but Honda back-spec'd 5w-20. I began using 5w-20 after the engine rebuild in 04 because of "piston slap" the previous engine developed. Can call it what you want, superstition. But when 5w-20 was available I used that after the rebuild. Sure it might have been coincidental but after 13 years no piston slap and excellent compression. But I didn't like how the Toyota/TGMO was thinning out. Way too much. I've also seen the same thing with Mobil's oil, of course they make it for Toyota.
I have switched to Castrol GTX Conventional since I don't want to go full syn, not on an older engine, not yet, baby steps. I know the whole thing about the marketing term "synthetic" compared to the real thing. But for now I'll see how Castrol GTX does in comparison to the Toyota stuff. If it thins out too, I will definitely take your advice about 0w-20, or 5w-30, I just dont want to get the dreaded piston slap again! So I feel that baby steps is appropriate.
So far with the Castrol GTX Conventional 5w-20, I have already jumped up 5.4mpg! I have done my research of the "old school" oil that this civic engine enjoyed and they had moly in them compared to titanium. Hey an engine likes what it likes. I'm not one to argue. I do know from what I've learned, moly will melt at a higher temp onto the friction surfaces, where titanium requires lower temps. Sure they do the "same thing" but it's not the same for this engine since the evidence is showing already. All I did was copy what was worked from the past (or similar to it).
I'll be updating this as I get more lab results but so far I'm happy with the change, we'll see.
and I would love to see those documents that show Mobil is using a trinuclear moly, always wanting to learn more.
EDIT: also wanted to add, if you notice on the UOA, you'll see I lowered the miles on the oil change and yup, lead wear went down, along with the evidence the Toyota stuff was NOT keeping up. I'm not that impressed. Nothing against Toyota but when there are such better performers out there, I wasn't going to stay with it anymore, thinning out way too much. I was using Toyota because it worked so well in my Scion tC 2az-fe engine, there was a time when this oil worked but something has changed. So onto something better then...
