Why is Honda 0W-20 so much more expensive than 5W-20
In response to your earlier post.. There is mineral oil added to all synthetic motor oils. It has been added to curb the leaking that was common with the 100% synthetic products when they first appeared on the market.
I started the van today and it leaks, Have to replace the valve cover gaskets. The car has been sitting but has synthetic oil M1 High Mileage 10w30. Oil is changing just like the gasolines. Thats why prices are higher too.
I suspect it's an urban legend.
Honda themselves will tell you, every manufacturer does this and any engine should be run with a high moly/zddp dino oil for break in.
Urban legend huh? Why is it with the internet at your disposal you couldn't be bothered to do some basic research and instead assert an ignorant "gut" feeling with no basis what so ever?
Here's a nice hot cup of shut the fuck up:

Yet here we are.

The additive is not in the factory fill oil, but the pistons are moly coated. This disperses gradually during break in. You do not want to flush it out by changing the the initial fill oil too soon. Note the high moly in the Blackstone report above. A large dose of ZDDP is not there because phosphorus degrades the cat over time, an emissions warranty issue. One of the reasons I prefer Chevron oil is moly in the Oronite additive package.

Think I'll be running Toyota's 0W-20. Easy for me to access and I have read very good things about it.
Its the cost to make 0W-20; there are components in the recipe that are needed to get to 0W that are fairly costly but thats not the biggest reason for the high cost. They don't have the volume necessary to justify the lower cost. If you produce a thousand gallons in the same equipment you make 100,000 gallons the unit cost is considerably greater for the 1000 gallons.
Oils, like food recipes, are full of additives to combat wear, viscosity change, and lots of others we don't talk about.

Al has stabilized at about 8-10 ppm, pretty normal especially since the 3 sigma variation is about 5 ppm. Fe also, interesting that Boron is decreased but Ca in increased ! That one involves some research.
It would also be useful if the friction level was checked by determing the power loss across a known gear train. That's the real measure of lubricant worth.

Do what the dealer does and throw cheap bulk oil of another viscosity in there.
It's all about "pour point" and most synthetics have a pour point of -40F or even colder, expecially the 0W20s.
And on what authority can you make this claim? When you say "full synthetic" are you talking about Group 3, or Group 4, or Group 5, or maybe Group 6?
