Thick vs thin debate...

[SR5]

like the 60 just posted about or higher (if there is any).

Yep, Penrite HPR 40 25W70

 

[aquariuscsm]

Deal !!
Not a problem and I certainly have before, year round and for years on end. Expect sometimes I ran Penrite HPR 30 20W60 instead, but I’m sure that counts.

I too ran 20W50 year round in my 87 Olds Trofeo. I sold it with a little over 350,000 miles on it. Didn’t use or leak a single drop of oil. I still miss that car!!

Toyota in Asutralia I think says it is ok to use 20W50 in 2GR-Fe, same engine that is specd. for 0W20 in US.

 

[edyvw]

@edyvw
I didn't imply anything. I said 508 cannot be back spec'd to vehicles that use 502 which is exactly what the links say.

Oh, I see, Mobil is looking to recommend 0w20 "where ever it can"?

Well, this is from Castrol EU...

I used to run/leak 20/50 in all my old VDub air cools.

2017 1.4 TSI....

Yes, they also recommend 5W-30 LL as the second recommendation too.

Of course.

So, how is that possible if only takes 0W20? Shouldn't engine disintegrate? By the way your first selection is Sportwagen. That is US model.

 

[JT20]

Making a blanket statement like that is silly. How about you run 20W-50 in ALL of your vehicles, year-round ?

Your signature says you run 20 weight in your Taurus. You can't get much thinner...

There is a range of thickness within the 20-grade spectrum.

The Taurus says 20 on the cap.

It can take a 30 no problem...

Put 20W-50 in it. "Thicker is better", as you say.

 

[JT20]

That's funny because it may very well run good on 20W-50.

I put what it says on the cap.

I would not put in 0W-16...

 

[Kuato]

I ran a 2013 F150 5.0 on 0w-40 (specified 5w-20). :hide: (
Guess what? Smooth. Quiet. No loss of power or mpg that I could detect.

All options taken from EU site for EU vehicles.

You seem to misunderstand my entire premise. I am not arguing that vehicles recommending 0W20 can only take one viscosity.

I agree that that's not the case BUT ALSO that 0W-20 is recommended in Europe (as first option for 1.4 TSi), and not just in the CAFE handcuffed U.S.A.

Why would it disintegrate? Poor quality on VW’s part?

Probably not.

I am just asking since apparently that is consensus among some. All Euro engines run on heavy oils, no exceptions.

The reason some engines are desirable with lighter oils is that EU adopted start/stop system earlier. That is why they give options. Actually, Mercedes is pretty clear about that and clearly states which approval is for what kind of exploitation.

 

[kstanf150]

That's why I mentioned M1 HM and M1 Truck and SUV. Both are heavy 5/30's. And with sales and rebates can be purchased cheap.

You can keep your "ribeye" oil. In the end it will not serve you any better than any other oil....at least not that you could measure. I'll keep the extra change in my pocket and upgrade to a $3 double cheeseburger

Redline serves me very well and there’s very much a noticeable difference. Well worth the cost

 

[ZeeOSix]

I keep asking my engine what it likes, but it just won’t tell me!

What was that TV commercial where the engine jumped out of the car and went tearing down the street because it wanted a certain oil?

 

[RDY4WAR]

good info!

I would have guessed less blow-by with the increased film thickness ... but I'm just an oil user and not an engine designer.

This engine has thin 0.8mm compression rings and 2mm low tension oil rings. The issue was the greater film thickness was increasing oil transport past the oil rings into the compression rings. The slamming of the oil around the ring lands and the ring grooves was unseating the rings causing flutter. An engine with standard tension oil rings most likely wouldn't encounter that issue no matter how high you spin it.
