Of course a number of posters here claim just the opposite. M1 being the quiter oil.


A number of posters here? Fair enough. Maybe 5. Almost every post I read that has anything to do with mobil 1,the poster claims more harmonics(great term) using mobil 1.
If you are going to copy and paste don't pick and choose the data,actually post what's really out there.
If I were to guess I would go as far as 75% of posts on mobil 1 claim more noise.
I find it funny that you would post this since there is an overwhelming majority that claims more noise.
Not saying that more noise equates to more wear,even though the uoa that I've seen using mobil 1 have had high metal reading but over the lifespan of an engine I think it's irrelevant. More relevant would be the maintenance schedule,not the brand of oil used.

I agree. At one point it was the best oil available to consumers,now it's no better,or worse than whatever is beside it on the shelf.

Plus 2

In reality - with an OCI every 6K to 7.5K miles either should be fine . Just saying I notice a difference in "harmonics" with PP. For grins , next time I am going to try QSUD to see if those Hyundai power plants growl or purr...

My car loves thin oil. On its second run of Castrol Edge and none of that "revving" noise the OP described throughout the entire OCI. Many oils, including QSUD produced this noise towards the tail-end of the OCI.

Your M1 sample was diluted by fuel (would be my guess)

I've been driving a vehicle that is sensitive to this. It's amazing how it happens sometimes and not others.

Mobil1 is arguably one of the most used synthetic oils. It probably has more miles behind it than any other OTC synthetic. If it caused even 10% of the things people here claimed it did it wouldn't be on the shelf anymore. I run M1 5w20 in my Kia Optima with 2.4L and guess what? It is still running and will continue to run for a long, long time.

I might just start doing a 10K OCI with Mobil1 and a Fram filter. Just to prove some of the people on this board wrong.

I'm not aware of too many posts in which M1 was described as being the quieter oil.
Could you provide some links?
My two cents is that M1 is neither better nor worse in engine sound than any other oil that I've used in the cars I've used it in. PP is quiet and smooth in both of the Hondas, but M1 was okay as well in both cars.
If the OP likes the sound of PP in his Hyundai, then who are any of us to argue the point?
Many posters have commented on how smooth and quiet SOPUS products seem in use.
Who really knows?
It may all be a placebo thing.
The more posts claiming that M1 is noisy and PP is smooth, the more posters who agree that this is the case?

M1 is not arguably the largest selling synthetic, it is by far the most sold synthetic. Remember, we have a fair number of M1 bashers here, with some actually stating they have a bias toward XM so they bash M1. One of Americas most successful companies isn't immune from that.

Nope, I don't save those post. But I have seen at one time or another posters claiming more noise with one oil compared to another. Like you, M1 keeps my engines very quite. Of course more M1 is used than any other synthetic by far so more complaints may be heard. The vast majority of non complainers never post. It's that way with everything.

Which FRAM filter?

Have used both oils and just seem to prefer PU alittle bit more. But both are fine oil.

Interesting; it's opposite in my car. PP 0W-20 in our Honda sounds rather clackity. At Caterham's suggestion, I drained out a quart and replaced it with Mobil 1 0W-40 and it made an incredible difference in noise. I have previously run M1 0W-20 in this engine as well (with no 0W-40 shot) and it was also very quiet. M1 seems to run the quietest in our Hondas.

Completely to the contrary, and in line with your Hyundai, M1 5W-20 was very loud in our old Chrysler 3.8L OHV V-6. PP 5W-20 made a world of difference in that engine.

It seems to depend completely on the particular engine.

I've long been a SOPUS user, so it took a lot for me to admit to myself that M1 really does run quieter in our current vehicles.

This is how the saying goes..."You have to find the oil that works best in your particular engine". Wheather it's the BUTT DYNO or UOA. Use what make you sleep at night!

I buy oils by price and am happy doing so! I always use oils that are held in high regard here at BITOG

And I won't use an oil that I have never heard of or seen before!

I don't really have any favorites per/say but, I have noticed that some oils do make the engine(s) more audible than others.

I have been surprised by some of the oils that I bought CHEAP that seemed to make the engines their quietest. Two that come to mind are:

PEAK 5W30 that I bought FAR about 3 years ago

SPECTRUM 5W30 that I got from SEARS about 8 years ago. Bought a case, CHEAP after Rebate.

Both oils cought me by surprise by how quiet they made the engines. Although I must admit, I have no UOA on either!
