You have your opinion, I have mine. If you want to run Mobil 1 5w30 when you get an LS1, go right ahead, but I won't run it when I get another one, nor will I recommend this oil to my friend's with LS1s either.

What are the long term effects of a little valve train noise?
What benefits does M1 give compared to other synthetics?

Noise =
M1 5W-30 is on the very thin side of a 30wt oil... its 40C and 100C cSt rating is almost the same as 0W-30 and 0W-30 Racing.
M1 10W-30 has a slightly higher 40C cSt rating but that just means it pours in slightly thicker, but once it heats up it's the same as 5W-30.
If you look at any other manufacturer's oil... their viscosities vary a lot more than M1's.
I'm experimenting with 4qt M1 5W-30 and 1qt M1 15W-50 in my Ford 4.6L SOHC V8. I tore apart the engine to slap in a pair of CompCams and saw how much the nylon guides wore with only 10k miles of 5W-30 usage (dino and eventually M1 5W-30).
I decided to do an experiment, run a slightly thicker M1 5W-30 and see if the engine noise dies out a bit. If not, switch to a much thinner weight since a few ppl noted their engines smoothed out with the use of xW-20. I don't know if its just pure 100% drivel or BS, but it won't cost me too much to run it ($1.80/qt).

I'd have no problem running Mobil 1 5w-30 in a Vette for daily driving. Only if I were to race it everyday would I look for a thicker oil/more additized oil such as M1R/ASL/maybe RL. And I'm sure after X amount of years my Vette would be running as well as yours. When is the last time you heard someone that blew up an LS1 bc Mobil 1 was in it?

I ran Mobil-1 0w-30 in my 96 5.7L Silverado from day one until I sold it just last summer and NEVER had any valve noise what so ever.
Same engine?
I'm starting to wonder if for some reason people around here just enjoy slaming Mobil-1
Thinking logiclly it seems to me if there is something to this that it has to be the viscosity. A thicker oil should quiet things better than a thiner oil.
I understand Mobil-1's 30w oils run on the thin side of 30. I'd just try a thicker Mobil-1 before assuming it's a bad oil or bad product.
I've had great luck with Mobil-1 over many years in many cars so I'm biased.

To answer the first question, if you're not seeing increased wear vs. something else, there is probably no long term detrimental effect. It's just noise. Turn up the stereo and forget about it.
For the second, from what we've seen on this board, M1 looks a lot like other quality synthetics. Good in some engines and applications, not as good in others...
Yep.
Yep again. I think that is what it is. In some engines, it's fine, in others it's not. There are people that complain that GC makes their car sluggish. Even 3MP said ASL is not as smooth as M1.

I'm begining to believe it's more the oils composition. I've run numerous combinations of M1 and the noise is the same. Currently running 15W50 and it's still noisy!quote:

buster,
Read your post and see if it makes sense. You agree with hankr that people here slam M1 all the time.....yet you say in the very same post M1 works differently in various engines. Could it possibly be that those that complaint about M1 be the same people you refer to having different experiences with the oil?
I have given M1 more than enough chances to quiet my engine.....and it hasn't. I should also mention that M1 combined with Schaeffer's #132 gave me outstanding results as far as wear goes.....so the oil seems to be as good as any other out there.....it just seems to have a problem with noise.

Actually I do happen to know a lot of LS1 owners who burn oil with Mobil 1 5w30, and then switched to something thicker and no longer burn oil. That definitely counts for something. A good friend of mine was burning 1qt every 3k with M1 5w30, and he switched to GC per my recommendation, and now uses no oil between changes (and he's stretching his intervals longer now too)quote:

Z I agree with you and Patman. What I'm saying is some people have LS1s with no engine noise, great wear and no consumption. Then their are some that have LS1s with engine noise using M1 and consumption. There are also people that go from M1 to another brand the car feels sluggish. I think it's a combination of the engine type, engine's condition and engine make. Yes Mobil 1 is thin, but I don't here many 0w-20 people complaining about noise.
Also, thicker oils will hide the noise, but that doesn't translate into reduced wear from what I've seen. It could be a ZDP issue more so then an oils thickeness, which is what you alluded to. M1R aparently quieted down George Morrisons car....only difference with M1 is 60% more ZDP.
seems like a lot of cars are noisier with M-1 5/30 and 10/30
Has anyone experienced increased noise with their Truck/suv 5w/40 also?
just curious...

I ran valvoline 10W-30 in my 3.8 = silent
Then I tried durablend 10W-30 = silent
I switched to Mobil1 for many miles = ticky sound
then switched to Maxlife 10W-30 = super silent
I've swapped back and forth, and anytime M1 is in my 3800-II, it ticks like a clock at idle... very noisy. With Maxlife she is quiet and smooth, no vibrations, and doesn't burn oil either.
I run maxlife because of this. I'm sure M1 is good oil for some engines, but not mine. At least not my valvetrain.
FWIW I've tried this on the following vehicles with the same result:
2002 Toyota Camry 2.4L 4cyl
(2) 2000 Firebird V6s
2002 Camaro V6
2000 Toyota Rav4

My wife's GTP with 10w30 M1 is noticeably louder. I don't know what was in it previously, but it's definitely louder. I noticed the difference immediately.
I was using M1 10w30 in my LT1 Formula with 47,000 miles on it. I did an Auto-Rx clean phase, now I'm using Havoline 10w30 as my rinse oil. The engine is louder now, but the oil pressure is higher.

Weird
During break in I ran original fill to 3500mi = fairly quiet
Valvoline 10W-30 to 5500mi = valve ticking for several seconds on start up
Amsoil XL7500 = ticking for a few less seconds
Schaeffer's = one or two ticks, then silent
Mobil 1 = silent, perfect, not one valve tick on start up. Purrrrrrrrrr
Could be the engine wearing in but my ear and my great analysis reports say Mobil 1 is the oil for me.

M1 0W40 TS was bad in my Mazda turbo. Used a lot too. Pennzoil Performax 100 5W50 now and i can only hear turbo whistle. Zero consumption too.
Hmmm...I'm thinking I would probably put a whole lot more stock in UOAs rather than something as subjective as perceived noise coming from my engines when making oil choices.
That's my thoughts too. I'd bet you could pack an engine solid with heavy grease, and it would be very quiet - right up until it siezed...quote:
