why no Mobil 1 Extended Performance 5w20?

[Kelton]

From what I've read here, Mobil 1 Extended Performance oils have respectable additives. I also read that there is some suspicion that the new 5-20 is a possibly a 'lesser' version of the old 0-20.
So why no 5-20EP?

Is the redline 5-20 a good option from my '04 CR-V? (I think it's a bit thicker, but don't know how appropriate is for a Honda given the copper issue)

10W-30 is the thinnest I'd use in Florida.

It looks like the argument continues on that issue. I take some probably 10 very short trips (2-3 miles) for every 1 trip over 5 miles...so that has me thinking that 'thin' might be good even in this hot stinky weather. Frankly, I can't decipher the numbers in the various charts in here. If a 10 weight oil is plenty thin in 90degree weather on startup, then 10-30EP would be terrific.
I will be taking a 1000mile trip in July though...so who knows?

If you read the label on the Mobil 1 Extended Performance, it says don't extend the drain periods for cars under warranty, for towing, for racing.
I'd be that most of the cars recommending (requiring?) 5W-20 are still within warranty.
For those that read their manuals, this would be a turnoff. For those that don't bother to read the manuals, most are convinced that they have to have something more viscous.

In other words, probably a limited market. Though maybe not as limited as the Mobil 1 Racing oil turned out to be!

Most car manufacturers call for 5,000 mile drains under "severe" conditions, and 7,500 under "normal" conditions. I think those are good drain intervals to follow under warranty or not. I personally will not go past 10,000 miles on any car. Why risk it? I believe that in time, we will see a long drain 5w-20 Mobil 1. Technically, I could run Mobil 1 5w-20 in my Honda for 10,000 miles, but I prefer the extra additives of the EP.

Blue, What "exxonMobil GrpIV" oils are you referring to as better options? The EP stuff?

Sorry for the confusion, I was referring to base oils and not the finished motor oil.

I posted links for info on this higher VI index PAO in This Previous Thread.

The lighter PAO viscosities in the 4-6 cSt range do have some volatility issues. The recent launch of the ExxonMobil Grp IV+ line of base oils provides some better options.

And looking at the 2.6 HT/HS of the regular Mobil 1 5W-20, this is just the opposite end of the spectrum from where the Euro extended drain oils are formulated.

In a 'round about way this implies that it's doable, but will the consumer currently be willing to pay the expense??

Amsoil has a 5w30 HDEO, but look at the price.

I think it will be awhile before a 20wt. extended can be cost viable.

for pcmo's.

Probably extended drain xW-20 aren't marketed, because it's not technically feasible.

Our 99 Lincoln recommends 5W-20 and has long since been out of warranty.

The market is there, but the thinner 20wt. probably can't be engineered to go extended, especially with current NA gasolines.

Why not run Mobil 1 Extended Performance 5w30. The Xw 30 Mobil 1 tend to be on the thin side of a 30 wt. Not really that far from a 20 wt from what I have seen in the VOA and UOA.
