So I know this doesn't really mean much in terms of oil performance but for me noisy oils just bother me. Super subjective too, I have never taken decibel measurements or anything like that...
I have a 2004 LS430 that has about 125k on it, I've put the last 12K on it since I bought it, it is an amazing car. But it has perhaps the most sensitive/oil dependent tappet-y sound of any car I've ever had (I've had A LOT of cars) but it got me thinking over my past cars and what oils I've tended to notice are nosier than other oils.
I've also been playing with oils to see what is really quiet in this particular car since it has seemed to be the most different from oil to oil. I've only done a few oil changes on this particular car but I've thought back on some of these oils I've run in other cars that also have been somewhat noisy on certain oils (S2000, Miata, Z06) and once I thought about it, these have proven true in most of my cars, so I figured I would share to see if anyone else has kind of landed where I have on these.
So these are the loudest to the quietest i've used (mostly 10w30 or 5w30):
- Mobil 1
- Castrol GTX
- Ford Motorcraft synthblend
- Amsoil (I only ran it in a 1.8T passat but it was pretty loud compared to whatever came out of it I recall firing it up and really noticing it)
- QSUD
- Redline
- Pennzoil Ultra (it was super quiet in our Honda Fit)
- Pennzoil Platinum
Now I don't know if there are specific things in these that make them quieter or if its car specific but its something I've always seemed to notice.
