Mobil 1 0w-40 or Pennzoil Ultra 5w-30

[tpaxadpom]

I have 550i 2009 and 2010 with naturally aspirated 4.8L T62TU motor. I have always been using Mobile 1 0W-40 in these cars. Right now there is a crazy rebate on Pennzoil and I was considering trying 5W-30 Ultra oil. Both can be sourced at Walmart. It is not euro approved oil and the Walmart doesn't carry any 5 qt Euro version of Pennzoil oil at Walmart (online order only).
I am not an aggressive driver and neither is my wife. I change oil on my car 2-3k miles (due to age, not miles) and wife's card ~5k-6k.
Open to suggestions. I don't have an issue continue on using it Mobil 1 but thought about trying Pennzoil as I can top off my Acura Legend 95 that is consuming oil in addition to rebate.

I wouldn't. The HT/HS is not sufficient for that particular engine. Likely wouldn't do any damage though.

 

[tpaxadpom]

Thank you. I should go back (continue to use) to the trusted Mobil 1 then.
Walmart carries Mobil 1 5w-40 as well as 0w-40, both Euro blend. I have been using 0w-40 most of the time (even before fs reformulation), but sometimes they are low on stock and I have used 5W-40 instead. I don't live in a cold climate. Is there a benefit of one vs the other?

They are pretty similar in characteristics to be honest. Someone has been developing a VOA database ("Virgin" Oil Analysis) where you can see the additive properties of 5w40 and 0w40. Here's a link to the thread. It's worth checking out. VOA Database

thank you. That is very helpful. Will check out the link.

Right now there is a crazy rebate on Pennzoil

Pennzoil Platinum Euro L 5W-30 Motor Oil - this should get you $10 per jug, you could buy 2 and this should work for your car.

Stick to XW40. Mobil 0W40 is better of two with more PAO/GTL content than M1 5W40.
Don’t go thinner oil with that N62. It will find its way easier through valve stems and that alternator bracket.

Will do. Thank you.

Unfortunately the Walmarts in my area do not stock this oil in 5qt jugs and rebate won't work with online order though.

I haven’t checked SDSs to see if that is true, but even if it is, it doesn’t matter to me. How the oils handle high temperatures does matter to me. We don’t have engine test results for M1 0W-40 and 5W-40, so we can’t evaluate them based on those ultimate measures of performance. We do have some test results in the following thread, and M1 5W-40 outperformed 0W-40 in terms of volatility and resistance to forming insolubles. However, I do not recommend either oil unless the person is constrained into using one of these oils.

What methodology was used to get these results?
Mobil1 0W40 FS is entry track oil in Mobil1 line up.

I explained the methodology in that thread. Some details are not present because they are in older test results threads.

I saw that thread when it was open. So Mobil1 0W40 FS is entry track oil for Mobil1 and has all approvals (I personally ran it to 300f on track and 5k OCI).
But, cool to know.

 

[JAG]

It will do alright on the track and normal street driving. My initial point is that I wouldn’t choose it over M1 Euro 5W-40, though the differences are not great. 300 F is a high oil temperature in terms of typical oil temperatures, but the good modern oils can handle that temperature for a very long time. If I tested at that temperature, I bet the test would have to go on for weeks or maybe more before I would start to see insolubles form. The oils don’t have to deal with the many damaging chemicals that oils do in engines. Compared to normal driving, the 300 F helps very rapidly volatilize the water and fuel byproducts, helping make the acids and other nasties less harmful.

My reference was that you would not use any of those oils. I mean, that is news for the Porsche team that uses 0W40 in 24-hour Daytona, etc.
So, ok, M1 (both) have Porsche A40 approvals, which have specific track requirements. “Any” oil won’t be able to pass that requirement and Porsche doesn’t charge approval that much (when I was working on that stuff it was around 4,000 euros). So, no typical oil won’t perform the same as 0W40 (or 5W40). 300°F is not normal for street oil. 300f is just oil temperature at sensor which mean, oil temperature is far higher in places where things get really hot and where having appropriate oil matters.
According to Mobil1 5W40 is GTL based, 0W40 is PAO and GTL based. That was my point, and yeah, I would use 0W40 without ANY hesitation in street or on track before 95% of oils available off the shelf. I would not trust many oils doing 1.5hrs long track sessions at 101f degrees at 5,100ft altitude.

Ok. I do not recommend either oil because I think there are better choices. I think the Porsche race team uses M1 because of a business agreement (M1 is factory fill supplier) and perhaps other constraints further narrowed it down to M1 FS 0W-40, rather than the brand and specific oil being entirely their call.

Sure, HPL is better oil, Motul 300V is better oil, Redline is arguably better oil on track.
The fact is that M1 0W40 is still doing 24hrs Daytona.
And which are those better choices?

We have a member here who has tested various oils, and his test results have been close with NOACK Numbers that are posted for these oil's. I think Jag knows what he is saying because he has done the tests that he has done. I am now using Mobil 1 ESP 5W-30 and in his tests show that the previous oil that I was using which was ESP 0W-30 did better in his tests, so be it. I had oil usage with 0W-30 versus 5W-30, what does that say about his test, his results are his results, and I like ESP 5W-30 better. What is interesting is that I am using the new formula of ESP 5W-30 yet on my next OCI I will be using the old formula of ESP.

Amsoil Signature Series 10W-30, and Quaker State Euro 5W-40 have very good NOACK Numbers, as well as a Quacker State 10W-30 that Jag tested, that is no longer available.

Mobil 1 0W-40 in the 24 Hours of Daytona is not relevant to cars driven on the street.

Let's appreciate all of the tests that Jag has done, the only way I would question him is if I did his tests myself.

This is not a track oil thread, so for street use in an engine like the OP has, I would recommend M1 ESP 0W-30, M1 ESP 5W-30, Quaker State or Pennzoil Euro 5W-40.

Don’t get me wrong, all are excellent oils. I used PPE 5W40 on track extensively and did a comparison with Motul in coordination with SOPUS.
However, basing that on your test, which is only one variable here is not something I would base my choice. I followed that thread, but volatility is just one variable. I agree, PPE 5W40 is an exceptional oil. However, there is no N62/63 engine where I would use XW30 oil, regardless that I personally also think ESP 0/5W30 are exceptional oils and I have used both in my vehicles.

As for not being track thread, it is not. Mobil1 as well as PPE 5W40 are street oils. My point is that Mobil1 is also entry track oil and being used on 24hrs circuit tells enough about quality. We are not talking specific racing oil, so we have concerns about deposits, etc.

Noack is the one variable. For example staple of racing oils is Motul 300V, but Noack is nothing special, around 8% for 5W40. But, it is first choice among racing folks. There is much more to it.
As for ESP< I used it extensively since first version in my vehicles when it had Noack 5.6%. It is very good oil. Personally, in N62/63 I would not use anything that is not XW40. Those engines like heavier oils, especially N63.

Absolutely it is if you use street oil in a 24hrs circuit. What other street oils are used in 24hrs circuit?

Let's appreciate all of the tests that Jag has done, the only way I would question him is if I did his tests myself.

Nowhere did I say I do not appreciate his test, but that is one variable, and it is a garage methodology. Sure, you get some results that you can observe and get some conclusions, but it is far from: I would not use either in N62. That is why I mentioned 24hrs racing circuit.
Again, I used in my BMW PPE 5W40 in winter, on track (it is my daily too) etc. I used ESP in BMW diesel, in Tiguan, etc. I think they are all exceptional oils. PPE or M1 0W40? IDK, toss a coin.
