Could it have thinned then thickened as it oxidized?

I also thought that a high Noack (14.4% per PQIA for Valvoline 5w30 conventional), means that the lighter fractions of the base oil will evaporate.


Certainly possible; however the recommendation was to extend to 7000 so I think it was good to go.

This one went out of grade. Maybe it's the fuel?

CAFE dominates our auto industries as a whole with the crazy mandated targets...DI, TGDI, CVT, 0/20 these gassers are really transforming too quickly.

I started using Mobil 1 5w20 in 1978 in my Dodge pickup. What CAFE?

Why a 5w-20 in Canada versus a 5w30? I seem to have no troubles with a 5w-40, and I live in one of the coldest parts of Canada, this side of the Arctic Circle. Additionally, in the summer, if it matters, we can also hit some of the highest temperatures on the continent.

The old Audi allowed 5w-20 in the winter. I'm sure it would be "okay" for the G37, too, maybe even the F-150, under cold enough conditions and sensible driving. That doesn't mean I'm going to try it in the summer. Generally speaking, if an oil isn't suitable for use all twelve months of the year, I'm not buying it in the first place.

As previously discussed, this was a 2.9HTHS oil, in an era when the 10W40s of the day were woefully inadequate, and when finally addressed were held to 2.9HTHS.

It's NOT the same as an ILSAC 20 of today, and shouldn't be used in the context of demonstrating such.

(But we go over...and over...and over)

but...
* CAFE was enacted in 1975
* all of the early papers which I've found that include this new synthetic 5W20 were based around economy while seeing if wear protection was maintained.

The oil crisis began in late 1973 and Mobil 1 5w20 was introduced in 1974.

Nothing like a sudden four fold price increase to get people thinking of conserving.

CAFE was enacted by Congress in 1975 but took effect in 1978.

OK, I'll just stick to...

That'd make it a 30 weight....

Good old days before CAFE in Year 1987.

In the commercial it's said, "6000 SUX. An American tradition. Because bigger is better."

Watch the 6000 SUX commercial below.

Took the words from my mouth. This is just plain trolling on the OPs part.

We resolved the reliance on German courts in 1945. Just adding some levity, not attacking. But what German courts today feel like is of little relevance to many of us. I don't always agree with U.S. courts either. That a bunch of lawyers in robes decide what is or is not a synthetic doesn't mean much.

 

[Shannow]

Chemists knew what "synthetic" meant...before marketing departments decided to stretch the definition.

Conventional 5w30 is also part of the big government CAFE conspiracy then.


Someone clearly doesn't understand how the cold rating works. Probably oil shear in general as well.

I think usa dealers benefit most from way thin oils.
Cafe might be just a nice way to ensure
there are plenty of cars in for repairs and i am not necessarily talking about engine wear. Its the other things that are attached to the engine like egr etc. In many countries people want to keep their cars forever due to economic reasons. Here as long as you get 75k to 100k miles the car is considered reliable by the dealer.
So thin oils with their high noack helps the dealers profit.
Ford mc 5w20 has noack of around 15%. What kind a repairs will that lead to? I would like to know?

CAFE (Corporate Average Fuel Economy) started in 1975, when Congress imposed it following the Arab Oil Embargo of 1973-74.

I don't see how a car ad from the movie "Robocop" is even germane.

And wear protection was maintained with Mobil 1 5w20 as it is today with Mobil 1 5w20 and Mobil 1 0w20. As someone who has used their oil all these years can testify. I used Mobil 1 5w20 in my engine calling for 30 and 40 wt oils.(I used Valvoline 10-40).
