Mobil 1FS 0W40, Honda Civic Type R FK2 , 2279km racetrack

[CarfriendXX]

Here is my analysis of almost pure racetrack operation. The third analyse from the left is with the honda Engine Type 2.0 0W20, the other two with mobil 1 fs 0W40. What do you think about it?

What will you Show us?

Are you using a moly additive with this oil or does mobil 1 fs 0w40 have more moly these days

 

[Oliveoil2]

0w-20 looks really good. No fuel dilution. So what’s with the 0w-40? I don’t see the need for it.

 

[CarfriendXX]

The 0W20 has Over 600ppm moly. The mobil 1 fs 0W40 has 80-90 ppm moly in a virgin analysis.

 

[CarfriendXX]

Should I stick with this or maybe switch to the mobil 1 esp 5W30?

 

[Popsy]

Is it a direct injection engine?

 

[CarfriendXX]

Yes, only direct Injection turbo.

What do you think about the importance of the noack value for engine oil? Everything under 10 is sufficient, or the lower the better?

 

[ceecbtg]

I would stay with 0w20 or try 0w30.

The harder you drive it the Lower it should be. JMO

Can someone tell me which base oil the mobil 1 has? Does it own mPAO? Does it have a high natural VII?

 

[RDY4WAR]

It's unlikely that Mobil 1 FS 0W-40 contains mPAO. I also don't see a reason for the 0W-40 here. The 0W-20 held up just as well and possibly free'd up a couple horsepower.

It's a mix, mainly PAO + II+/III or PAO+GTL

In terms of wear values, certainly almost the same. However, the w20 engine oils are all mid or low saps. Since my car stands for a long time over the winter, I would like it to be particularly well protected. Furthermore, w20 oils are more prone to volatility and thus deposits, for example, on the turbocharger shaft. With exclusive summer use, higher viscosities are certainly an advantage.

What do you think about the VII? Does this not "best" base oil have more polymeric than other viscosity with "better" base oil?

You can make a 0W-20 with the same or even higher initial base oil as 0W-40, plus possibly better base oils, and thus about the same or better volatility. The Noack for M1 FS 0W-40 is 8.8% while Ravenol DFE 0W-20 is 7.6%. Amsoil Signature Series 0W-20 is 8.8%. The first number has far more relevance to initial base oil and Noack than the 2nd number. A 0W-20 and 0W-40 both start out with similar blends of 4-6 cSt base oil and use VII to boost the KV100 to the appropriate grade. A 0W-40 will need a lot more VII than a 0W-20. Aside from shear and solubility concerns, VIIs tend to have a lower flash point as well which doesn't help matters.

I wouldn't hesitate to run a quality 0W-20 like Ravenol.

How can a 1,000,000+ molecular weight polymer have a low flash point?

Usually natural VII from base has better behaviour than added after, but is not easy to formulate. FS both formulations have very good uoa results and good VI, so nothing to object for me.
