On some engines, absolutely it does.
What he said!. My 2015 Equinox AWD w/2.4 Ecotec had a minor drone with factory fill. Drone was worse with Mobil 1. Much, much worse with QSUD. Drone GONE with 5w30 Magnatec.

There are better oils available from Castrol and other companies and although it is good for most normal petrol cars, I would not use in a turbo or use it for extended OCI's, particularly in a diesel.

Anyone got the VOA ??


Apparently Magnatec was the factory fill for Jaguar until they switched to the new proprietary 0w-20 Castrol Edge Professional. Before Magnatec they were using 5w30 GTX.


Well I guess that explains "gotta own two Jaguars to keep one on the road"...


Not sure how that pertains to the oil conversation but as someone that has owned two Jaguars at the same time(three if you count the Lincoln LS) there's some truth to that! I'd get a newer Jaguar XJ but I really like not having a car payment.

Good to hear since I have 16 quarts of the stuff. I've been wanting to try it for awhile and with the Advance Auto score it was the perfect time. Plus scored 3 quarts of Havoline conventional.

How were you measuring that? Or are you telling us you can feel it?

I have been driving for 50 years and have owned many cars.
All the way from a 1966 Street Hemi to a 4 cyl.
I never had any car that ran bad because of what oil was in it.
Someone please explain.

Hey Dallas... What could anyone say that you would believe?? I am not trying to give you a hard time here. I am just curious as to what your threshold is for believing someone else's account.
I can understand what you are saying from all of your years of experience. Is it legitimate?? Of course I believe it is. Because I trust what you are saying. You know what you've heard and noticed over all that time.
I will say that I've noticed some differences at times. I had run Royal Purple API SN one time and it had a lot more noise at startup and running down the road. I changed the oil Castrol gold bottle and filter. Noise was gone and never heard again. Now could it have been the filter possibly. But I'd bet it was the RP. Now, RP is a very good oil. Especially the RP HPS version. For some reason it just had a lot of noise when running that.. The Camry my lady has runs a lot quieter on Motorcraft than it did on anything else. Just my observation. So, I do believe that when other people say they notice a difference at times too.
But I also believe what you are saying too. You know what you've observed as well.

Well, it's not like there are not ways to measure noise and vibration. I'd love for someone to come with data, that would be very interesting. There are ways to measure how VVT is working, too, which would also be interesting.

I am not talking about noise.
I am talking about oil actually making an engine run bad.
That was the original statement I believe.
Most startup noise is caused by the filter used anyway in my opinion.

This is the OP and just to clear things up the motor in my 2012 Nissan Pathfinder is the VQ40DE 4.0 V6 and it has a rather large timing chain that makes noise on start up more so when real cold. This is the only car or truck I have owned that the oil seems to make a difference when it gets near or below zero the difference as in start up noise and I find Castrol Magnatec 5w30 seems to be the quietest on start up. I have never really noticed a difference when running just start up. And this is the only motor that I can notice the start up noise difference.

Well I agree with you are saying to a good degree. I do think noise does matter to an extent. When my oil was 2 qts low in my Ford Probe in 98 it certainly was making some noise. I didn't pay attention like I should have been at that time. Or when 2 yrs ago my step fathers Avalon was 2 qts low and it just sounded noisy to me. Pulled the stick and dry as a bone. Or like when my lady's car blew out all 4.5 qts in a half a mile and she drove another 4 miles. It made all kinds of noise the last mile and a half she said.

Again, those were obviously circumstances where oil levels were way off. The cars obviously ran noisy and were not running a bad because of the oil used but a lack of it.

I do think that you are right in that an oil used that is the correct viscosity would in almost all circumstances not lead to a car running "bad". Does noise with a correct viscosity and level mean it's running "bad"? Unless someone were to do a tear down of numerous motors in which all of the above criteria were met then we could maybe ascertain an answer.

Okay. We have engine dynos and other tools to measure "running bad".
