I was debating on running this or the mobil 1 5w50, I'm still waiting on the results of that to come back. I'll follow up when I get that one in.
I've actually got the mobil in the pan now.14.7 KV100, 4.7tbn and 2000+ ppm zinc? Edit: just noticed this is a race oil.
I think M1 5w50 would be better in both circumstances, high TBN, KV100 of 17.4, HTHS of 4.4 (a real 50) and has Porsche A40 approval.
Uh...yes?You're making an oil choice via the results of a $30 spectrographic analysis?
It's a technically poor way to choose an oil. UOA do not discriminate oil quality. People keep trying but there is no technological basis for that belief and the analysis labs will be the first to tell you the same.Uh...yes?
Don't act like this is abnormal.
You mean actually listen to the experts?? Pshaw, why would one do that when they can rely on feelings and presumptions? /sarcasmanalysis labs will be the first to tell you the same.
you mean the lab that tells me what's in the oil so I can decide whether it suits what I'm looking for or not? Kind of like this report?You mean actually listen to the experts?? Pshaw, why would one do that when they can rely on feelings and presumptions? /sarcasm
A list of ingredients won't tell you how tasty a loaf of bread is.you mean the lab that tells me what's in the oil so I can decide whether it suits what I'm looking for or not? Kind of like this report?
If that were the case then no oil blender would have to run the suite of tests in SAE J300 or the even more extensive validations that are in a manufacturer approval or specification. All they would need is a $30 UOA and a relatively uneducated interpretation.you mean the lab that tells me what's in the oil so I can decide whether it suits what I'm looking for or not? Kind of like this report?
I'm sure they are; so far the 5w50 mobil has held up well to my hot running 416 iron stroker. Add to that the heat of the eastern plains of NM and I still stay between 100-105c oil temps and around 38-40 pounds of pressure at hot idle with a stock radiator (for now) and it's doing well.Both are excellent motor oils. Reference is made to my previous post.
MolaKule is this board’s preeminent oil expert, because he actually works in industry in the formulation of oils, and how their additive packs interact to provide the necessary protection needed for a given spec. One would think that when he posts that a true lab test to identify everything in an oil that is relevant to certifications and performance costs several thousand $, and that a VOA/UOA does not provide that information, people would listen. But you’re free to do as you wish.you mean the lab that tells me what's in the oil so I can decide whether it suits what I'm looking for or not? Kind of like this report?
So you called the manufacturer, they told you for your given application it would be fine, and then you assume after that fact that you’ll have to “change it much sooner” even though the manufacturer just said it would be fine?when I called and asked Schaeffer's I was told it would be fine for daily car. So now I know if I run it on the street I'll need to change it much sooner than I would have initially expected.
Did you not see the TBN?So you called the manufacturer, they told you for your given application it would be fine, and then you assume after that fact that you’ll have to “change it much sooner” even though the manufacturer just said it would be fine?
Yeah, sounds like science.
A couple of things unless I’m too weird for you. First off if that is race oil then it may indeed be “fine” for use just like they say. But I’ll agree that a high TBN is not an objective of a race oil.Did you not see the TBN?
I heard this place was full of gate keeping weirdos, this is wild though.
