Mobil 1 vs. Toyota 0W-20 - 4000 Honda Insight 1.0

[veryHeavy]

The three-cylinder engine ran each oil 4000 miles. The Toyota oil appears to have high levels of Moly and calcium, but there's no evidence it provided extra protection.

Code:


TOYOTA MOBIL

3 2 aluminum

0 0 chromium

4 4 iron

2 2 copper

0 0 lead

0 0 tin

Both oils kept the parts separated.

It appears to me that the M1 controlled the acid better. And although 1ppm may not be significant, by percentage the M1 test shows only 67% of the iron that the TGMO did.

Based on the UOA's I'd use whatever is cheaper and easier to get.

That's because molybdenum is primarily a friction reducer, not an anti-wear additive.

Any idea why the Toyota oil has such a high TAN?

 

[Garak]

Where's the VOA of that specific formulation of the Toyota 0w-20? Without it, how high is it, really?

Because at 4000 miles virtually any oil you dumped in there would have worked the same. Can't judge the winners of a marathon 5 miles in.

Agreed. This is pointless at best.
