I'd love to hear from the knowledge gurus regarding engine sound changing with different oils. In audio world there's an omnipotent myth that different amplifiers/av receivers have different sound signature. This has been definitively disproven with scientific blind tests, time after time.

I would guess that the same holds true for "this oil quieted my engine" or "that oil made my engine sound coarser", assuming identical viscosity is used. So, how can, FOR EXAMPLE, 5W-40 oils with the same MB 229.5 approval, but from different brands cause engine sound signature to change, as is often claimed? I can understand a lighter weight oil vs heavier weight oil causing a change in sound signature, but again, same 229.5 (JUST AS AN EXAMPLE), in the same viscosity, just different brand producing a difference? Sounds like a typical human myth to me.

What do you say?

I see a lot of opinions on noise and no data.
Which tells me most of the opinions are worthless.
(since you don't need a 3000 dollar B&K sound meter any more to measure this stuff).

I mean, the fact that two oils meet the same standard doesn't mean that they are identical in any capacity. Similar, sure. But there is still latitude for the manufacturers to design an oil as they wish, so long as it meets the spec they say it does (perhaps calcium vs sodium in the additive package). And viscosity isn't necessarily identical within that spec. Again, it can be similar without being the same. Different enough to make a difference? I can buy it sometimes, in some cases. Will that difference be tangible and/or matter? Probably not. For example, the PP Euro and M1 are not exactly the same product despite meeting the same spec, 229.5. There are many examples of this (for example, not all TT gas is the same - Shell doesn't necessarily use the same additives as Chevron or Mobil or BP, but they're all TT). The fact that it performs similarly, and is certified to do so, does not mean that it is the same product, or that it will necessarily perform the same way in all conditions. What it does mean is that the initiating party agency (in this case, MB) says that the product meets their standards. The companies making it are free to do so as they want, and some differences should be expected.

In Engineering world it is called "Tolerances".

Most spec is stated in a range of value, NOT absolute.

For example:
Absolute value "5".
Then when it is expressed as a range: 5 +- 5% or 5 + 5% or 5 - 5%.
Note, the first one is "plus minus", second is 5 or greater up to 5% of 5, etc.

So a company can go on the minimum, maximum or the middle of the tolerance.
Nothing in this world is really absolute.
Will it ever be 5, heck no.

This spec is valid for the oil and the car.
Means both the cars and oils are made based on tolerance NOT absolute.

The 3.5L V6 in my 2010 Challenger would sound like a typewriter when started any morning when ambient temps were below 50F and the engine oil was conventional 10w-30 of any brand (IIRC QSGB, PYB, and ST were all tried with no relief).

A switch to Valvoline Maxlife 10w-30 stopped the typewriter noises on the colder mornings the very first start, and the noises didn’t return as long as I ran that oil.

I won’t say I know what is about the MaxLife that quieted that engine so completely, nor will I say Maxlife is the best oil for other applications. Whatever it was, however it did it, Maxlife 10w-30 and that terrible Dodge V6 worked well together where others would not.

My 2006 Honda Odyssey 3.5 sounded significantly different with 5w-20 vs. 5w-30. The 5w-30 was much quieter.

In my 5.3 Chevy truck, I cannot tell any difference between 5w-30, and 10w-30, or even SAE 30wt.

My engine sounds different at different times of day/drive with the same oil. Good luck trying to ascribe a change in sound to oil.

Sometimes the typewriter sounds are stuffed inside the oil filter and not in the oil galleys.
So when you switched to the quieter Maxlife, you also switched oil filter brand / model too?

Or, have you stayed with the same exact oil filter, throughout the entire ordeal / OCI changes?

Maxlife full synth or synth blend?

That engine got nothing special in the way of oil filters. The normal one would have been the MicroGard filter from O’Reilly Auto. If I strayed from MG for that car, it would have been a standard Wix oil filter.

Also, I usually run an oil filter for 2 consecutive OCIs unless something happens that prevents it. Whether or not a coincidental change from MG to Wix occurred right at the swap to Valvoline Maxlife, I cant say with any real certainty I remember that happening.

IDK...whichever one comes in the red bottle and whispers sweat nothings in old Dodge V6s’ ears, that’s the one!!

That's the synblend. My former S-10s 4.3 engine's favorite oil. Always popular with BITOGers, as is the Valvoline Durablend..

Earlier this year, I was running Shell gas truck 5W20 in my old crown vic police interceptor and it idled funny like a slight miss and had "meh" acceleration


I switched to M1 truck/SUV 5W20 and HOLY MOTHER [email protected]&! talk about a big difference in engine sound and torque/acceleration !!


STRONGLY thinking of running it in my Suburban/Silverado work fleet thumbsup
