I never noticed it when I switched to M1 EP, but I took a careful listen to my engine idling this morning just before I drained the M1 in preparation to switch back to Havoline dino. As soon as I started the engine with the Havoline in, I immediately noticed all the mechanical thrashing sounds it was making with M1 were now gone. Nothing but a quiet, smooth running engine. I wonder why this is?
Now I know what you guys meant about M1 (noisey)

What kind of car do you have?
I dont know wither but I had the same thing in my truck also. it was noisy and I drained it and it was quiet when I put another brand of oil in. all I know is I wont be using M-1 again. maybe its the group 3 basestock compalining about being labled full synthetic
Dino oil is thicker than most synthec oils. The noise at idle has little to do with wear.

Your M-1 was probably quiet when it was first entered into your engine -- much like your new Havoline. Wait a 1000 miles & you may hear the old sound again. I read similar things here right after oil changes -- like how much smoother the engine runs too. That doesn't seem to last very long either.

Whatever it is, I've washed my hands of the M1.
Just put in my M1 0w30(
) it's as quiet as a chuch on prayer day, love the stuff...
I'm with TripleSeven on this.
I put 5w30 Havoline last year in my 2001 Solara & it became noisy after 1500 miles.
I also put 5w30 Quaker State in my 2000 Subaru, and after about 1000 miles, it too became noisy.
Switched back to M1 on both cars. Smooth ever since. Just my

The T&SUV is smooth in my Racura.

I ain't switchin' back to M1 no matter what.
My Harley has this issue as well but the Mobil1Vtwin is the oil that smoothes it out and quiets the top end clatter that all TC88 HD engines have. Mobil1 5w30 runs real quiet in my Vortec 6000 but noisy in my kid's Honda CRV where PP is the quiet oil.......who knows??
Did that same thing with Redline to Mobil1. The Redline 5W-30 was quieter than Mobil1 new even after 10K miles on it. So much so that the guy next to me stopped me to ask what happened.
When I did change back to Redline after a week of Mobil1 same game again. Redline was much quieter. That was back in 95. Oh well.
So far so good on Havoline 5W-30 now in my neon.

Bad, BAD, Mobil1
Stop with the noise, or off to the corner for a time-out you're going to go!
Naughty, noisy Mobil1
The imagination Dynometer has GOT to be in overactive Thyroid mode with the noise. I'm sorry, there's GOT to be some way to quantify this noisy M1 (bad, bad M1!
) in some empirical measure. Oil is oil. I wish there were some double-blind Pepsi-challenge experiment we could do. We got a couple or three or four BITOGERS in the same geographical area willing to give this a shot? Some sound equipment, a camera, couple of beers, what the heck?

Let's see... motor oil with cleverly deleted total miles on it compared to virgin motor oil with, hmmm... no miles on it and an unmentioned reference that after initial shear-down, all motor oils increase in viscosity as unfilterable particulates increase. Does anyone else besides me see a potential inconsistency here?
By the way, noisey the diurnal human hearing response varies markedly from various internal and extraneous factors. Next time, instead of relying on your assumed perfectly consistent hearing abilities, use a calibrated microphone connected to a level meter.

You're funny. You are actually incinuating that I'm trying to pull something here. While I didn't list how many miles were on the M1, I DID mention I was about to drain it because I was at the end of an OCI. BTW, the M1 was the EP version and it only had 9K miles on it (on an oil that's supposed to be good for 15K miles no less). Sorry the test wasn't conducted by engineers in a sound proof lab with mics and decible meters and such so that it would meet up with your standards, but I know what I heard. Now you best get back to your trolling you pesky M1 fan.
I insinuated nothing. I pointed out that without stating the mileage on the old oil, no valid conclusions could be drawn. 9K miles is enough to increase the viscosity of any motor oil - especially if some of it occured under hard driving and/or hot weather conditions. I'm neither a fan nor a detractor of M1. I also stand by my outright statement that trusting your own hearing repeatability to be an acurate assessment of relative noise levels is NOT realistic. It's NO reflection on you personally - that's WHY labs rely on instrumented findings. (Take your troll-referenced insinuated name-calling somewhere else, 92 post, newb.)
