We often read how much better someone's vehicle idles, sounds or feels depending on the oil viscosity used. Never having paid attention to it before, i couldn't make any distinction as an afterthought. This time around i thought i would go into these oil changes with that at the forefront. Well, i still can't tell a difference. Might it be my location.

Am i sensory deprived or are you guys just 'hyper-sensitive'? wink

Some people's butt dynos are so sensitive, they can tell when a fly on their bumper is slowing them down.

The mind plays tricks on the hearing, if you want to hear a difference you will. I use my wife as a test subject, I don't tell he anything I do to her car, it would be a very rare occasion that she noticed anything.
She does notice engine noises but never after an oil change.

This might be an important distinction.

Wemay you carry the diagnosis of CHS... Can't Hear Stuff= or the other word smile

You may also carry another diagnosis of CFS.... Can't Feel Stuff.... smile


I do think age, mileage and motor matters a whole lot here. Newer cars and trucks it will be different than a vehicle made 15-20 years ago. On my lady's Camry there can be rather noticeable difference between oils run in it. Motorcraft and Valvoline Maxlife full synthetic run way quieter than others I have run in it.

Hearing any difference in engine sounds based on type or viscosity of oil is kind of hard with these new high pressure fuel injectors. Back when conventional oils were used more, I was attuned to things. I didnít really focus on the sound or smoothness of the engine. I observed oil color and fuel mileage. Lightest color to darkest color I used were Valvoline, Texaco Havoline, Pennzoil and Castrol. Of all the oils I listed, Valvoline gave me the best fuel economy. Now that was running the same viscosity oil in the same vehicle. This held true through 3 different vehicles, a Ď91 Ford Ranger 3.0, an Ď01 Dodge Dakota 4.7, an Ď03 Dodge Ram 4.7. The fuel spike after Katrina put an end to the gas hogs for me. Remembering these things, I have some Valvoline 5W30 Synpower waiting to go in my Escape.

^^ That 2.0T in the Escape is an impressive combination.

Impressive is an understatement. The thing is a rocket ship. It took some getting used to. The 2.4 KIA ainít too shabby.

Going to a more viscous fluid will dampen sound waves. The thicker the fluid, the slower sound travels through it. However, I'm guessing you'd have to run a 50w oil in something that normally runs a 20w to even begin to hear a difference in perceived engine noise.
