Mobil 1 ESP 0w30 observations

I´m sure some interesting responses will come to that question, but honestly, wouldn´t you have to drive an engine nearly exclusively using that oil until it wears out to get the real answer?
That is correct. Many think you can run an oil once and "see how the engine likes it" and make a determination. But differences in oils are seen over 10s of thousands to 100,000+.
 
Neither one would be even close to the best oils for any of my cars. Know your engine's requirements and base your fill around that, not around MB 229.5 or Porsche C30 or VW 508 or 509 or whatever. They're tough specs to meet but are only optimized in vehicles that need the properties and characteristics they provide.
What are your cars?

How would you even know this? How can a better oil be worse for your car? I think you're ill-informed.
 
Maybe so, not all that interested in arguments I've got better things to do with my weekend. I've posted my vehicles in the latest oil change thread. None of them need a C3 oil with emission system protection so won't be spending $60 CAD for the new jebus of engine oil.

I do appreciate all the information though so thanks to all (y)
Just keep it technical and that will help. Really. Avoid terms like “leghumping” and explain what you’re trying to say in clear terms and people will listen.
 
True. You have to be selective.
For you, the small price disparity is fair and you'd buy the ESP?

Which vehicle again?

If you don't require low SAPS, then I'd happily run the Mobil 1 Full Synthetic 0W-40. If you have a GDI application, I'd run the ESP though too I guess. Might help with intake valve deposits. If port injected, Mobil 1 Full Synthetic 0W-40 will serve you well.

None of my cars require low saps and all will be very happy with the 40 weight. That answers my question thanks :) (y)
 
C30 + 229.52 + 0w30 = Ideal Oil.
Shear-stable 0w30 with ultra low oxidation/wear/deposits ...Mobil ESP 0w30 is ideal for most all applications and regions.
Fair enough but all but one of my vehicles would do better with the 0W-40. This 0W-30 ESP sure does appear to be the real deal though. I actually have a jug of it in 5W-30 that I picked up last season currently sitting on the oil wall (y)
 
Have you noticed that you had to increase the radio volume? 😁
In the mid-'80s one of the fellows at work was selling Bitron additives.

IIRC, the literature warned that if you had a carbureted engine you might have to turn down the idle speed. 😜

The seller himself told us of adding it and then pounding the dashboard because he thought the fuel gauge was stuck on F. No doubt he was sincere, but I think there was an element of placebo effect.
 
For me it's ESP and it's not even close. To me it's nonsense to dictate chemistry limits in a spec, especially one that results from a roomful of "experts" voting on something. It's as stupid as having rules like NFL QBs must be 6'4" tall at least (a rule that cause the Chargers to say goodbye to one Drew Brees, who it turns out could play QB at least as well as the taller Phillip Rivers who displaced him).


Absurd arbitrary limits are all around us, creating pretend differences of kind out of differences of degree. Yes, one could draw a line at 68F and say everything below it is "cold" and everything above it is "hot", but at the margin, 67F and 69F are only two degrees different. Yet the categorization implies they are as different as -20F and 120F, which also fall into the same separate categories.

Nature is analog and any perfectly round value is almost certainly manmade and arbitrary. This is why PI was discovered, not dictated. As was the golden ratio, Euler's number, avagadro's number, etc etc.

There is a place for abitrary limits-- mostly in politics. But in the apolitical arena of science and nature, limits should be discovered, not dictated.
This reminds me of the heat stove on my '71 Toyota Corolla.

GM used a vacuum-operated system with thermostatic control (AC Auto Thermac, or something like that), whereby a damper would open or close, feeding either cold outside air or air heated off the exhaust manifold, into the air-filter housing.

The Toyota had a wing nut on the outside of the housing, attached to a sliding curved plate inside. In summer position, the plate blocked off the pipe running from the exhaust manifold, and admitted ambient air. In winter, the plate blocked off the ambient air and admitted preheated air.

Instructions on the housing next to the wing nut advised the summer position above 68°F, and the winter position below 68°F.

I wonder how many people made the seasonal change.
