M-1 oils.....make engines noiser ???

I have a Duratec focus also - mine should be same as OPs but just smaller displacement. I don't have DI or any sort of variable valve timing. Mine is quieter on Mobil 1 0w-20 than it is on 5w-20 or the 10w30 (I know, I know ... it was cheap) that is in it now.

I have run two brands of 0w-20 in it. When it was new, I was using Castrol Edge 0w-20 when it would go on sale at Advance Auto parts and I got a good discount. After that I used Mobil 1 0w-20. Both times the 0w-20 were quieter.

I have been trying to drag this OCI out as long as possible, but hopefully end of October I'll be switching back to some Pennzoil Platinum 0w-20 ... whatever that is ... and I'm sure it will be nice and quiet

I can attest to that. Anything I tried with high boron made the valvetrains in both my old Subaru and my wife's Corolla a lot quieter, be it conventional or synthetic.

I an also agree that certain oils make certain cars sound louder or quieter. The Subaru sounded fine with Mobil 1 but was noticeably quieter when I switched to Synpower. The Corolla sounds butter-smooth on Castrol GTX dino but clackety on both Pennzoil conventional and PP syn. So is that a dino/syn comparison or a Castrol/Pennzoil difference? Who knows, but the results are real.
 
I noticed the same thing on my old 2005 focus. It would be quite loud on M1 and then when I switched to motorcraft syn blend the engine got very quiet to the point where I thought it was not even on at idle. I thought I was just me until my friend asked me what I did to my car because it was so quiet. We could even have a conversation between the people in the back and the people in the front.

I like M1 and the car being a little louder wont effect the protection the oil provides but there is definitely a difference in noise level for this car at least. Funny to see this same observation here on the same car.

"Everybody"?


Troll-kava strikes again, LOL!!

Regarding the OP, nope, my wife's 5.7L HEMI sounds the exact same on the dealer Pennzoil Conventional 5w20 as it does on AFE 0w-20.

The BMW was actually quieter (slightly) on Mobil 1 0w-40 and Pennzoil Ultra 5w-40 than it was on the BMW 5w30.

The Expedition sounds the same period regardless of whether it has 5w-20 or 5w-40 in it.
 
I had Mobil 1 5w30 in our Subie and switched out this time for Quaker State Ultimate Durability. No difference and this engine isnt exactly smooth.
 
Nope. In my F-150, I started with Pennzoil Ultra 5W-20, switched to Mobil Super 5000 5w20, switched to Mobil 1 Advanced Fuel Economy 0W-20, and finally to Mobil 1 Extended Performance 0w20. There was no "extra" noise caused by M1 and as for the iron shedding, my used oil analysis never showed that M1 shed more iron than any of the other oils.
 
My Equinox and Malibu ran louder on Mobil 1 High Mileage. Neither are known as quiet engines but the current combos I have in there seem to make the engine the quietest I have experienced.

I'm wondering if any of you guys have had a similar experience after switching from M-1....to another synthetic.


Not here. I've never heard oils of the same viscosity sounding any different at all. Thinner or thicker- maybe a slight change. Different brand? Imagination.
 
If no significant noise difference can be measured between 10W60 and 0W40, I highly doubt there's any difference between brands of the same weight. But go ahead, keep on telling yourself you can distiguish noise change that machines can't.
 
I have no idea what oil was in my hemi when I bought it but Mobil 1 Extended Performance didn't change any noise.

It has a little tick but nothing I'd call "the hemi tick".

It sounds the same as the last ohv engine I owned. (2000 ls1 camaro)

Even my ranger 4.0 has a slight tick if you listen real close. I'm thinking it's just a common valvetrain noise to ohv engines.

My 5.4 f150 had injector tick before developing cam phaser tick.
 
When it comes to engine noise it's hit or miss depending on the engine type and oil. I've never found any consistency or pattern between brand/engine noise.
 
It's confirmation bias.

Someone notices an engine tick that could have always been there. Blames it on last brand oil used.

Buys a more expensive/cheaper oil. Tick seems quieter/noisier. Current brand is better/worse.

Eyewitness accounts are among the least accurate pieces of evidence. There have been many studies demonstrating this. Which is why I suggested measuring it with a readily available instrument. Apparently that is a silly idea, though. What is really silly is the number of people that hee and haw about this but refuse to actually prove it despite claiming that the difference is "dramatic"; if it is so dramatic, measuring it, even with crude instrumentation, should be easy.

Quaker State Ultimate Durability quieted the engine from M1? What is your OCI withQuaker State Ultimate Durability? I plan on a 7500 mi OCI on Quaker State Ultimate Durability.


Thanks for verifying thatQuaker State Ultimate Durability quites engines. I believe it has high moly content, so that might be the reason.

I intend to do an OCI between 7500 and 8000 miles. I currently have 1100 miles on theQuaker State Ultimate Durability fill.
 
Oregoonian: have you ever tried the older different decal scheme QSED? It's their synblend and I have 3 jugs that Wal mart clearances for $13 and its 2/21/2014 stuff. That may go in the 03' Taurus of mine. This is 5w20 synblend
