GC and engine quietness

I put GC in my old Nissan truck about two weeks ago. Before it made a bit of engine "noise" at idle, you know valve train and mechanical noises that an 11 year old engine would make. I had been using Havoline SM/GF-4 5w-30 in it (the one with all the moly) and it was noisy and even used some oil in the roughly 2800 mile oci. Well after 500 or so miles on the GC that noise is gone even on cold starts. I was shocked that an 0w oil would do that. Chalk one up for GC in my book.

GC is pretty much thicker than Havoline 5W30 at all temperatures you would see in NC.It's almost a 40W.

The switch to GC made an immediate change in the noises that were typically emanating from both of my GM 60 degree V6 engines; '00 3.4L with 48K miles and a '01 3.1L with 36K miles. Both had been running 5w-30 Mobil 1 with PF-52 sized Mobil 1 filters. No more cold piston slap, no more cold lifter noise. Even the warm idle is much more quieter. The wife (a true non car person) noticed the different right away, even without me pointing it out to her. She was amazed that simply changing the brand/type of oil used could make that kind of difference. So was I [Smile]

I noticed the same thing. Much quieter than the M1 I was running in our daily drivers. I asked Pscholte in a PM if it was just my imagination...... but now I see that your elves quieter too! [Cheers!]

Well, sorry but the tears are just going to have to flow a little bit more.. [Big Grin] . My Grand Am (04 3.4L V6) was the same way...INSTANT reduction in startup noise/piston slap/valve train clatter/what-have-you. I too was running M1 5w-30 and it was noisy as h*ll, and it made me cringe every morning when I turned the key. But now it's all good [Cheers!] [Happy]
 
Just a few of the comments from new converts... GC has reduced noise and vibration in my Toyota V6 so much that I can't tell if the engine is running sometimes. Especially if the radio is on.

The music...its getting louder....so all can hear...we need BUMPER STICKERS...that proclaim we love GC!!! I spoke with the Elves and all their manufacturing abilities are into producing the Green Elixer...no time to do bumper stickers.. [Frown] We need a way to recognize each other... Just IMHO darrell sin city

When I used GC, it definitely made my engine quieter than the M1 0W-30 I used previously, and slightly quieter than the Pennzoil Platnium 5W-30 blend I'm running now. HOWEVER, I can't get away from this, it also reduced my mpg compared to those other 2 oils, and made my engine's dynamic response more sluggish.

As the Elves like to say, "Negatory, good buddy."

Not sure what engine your running bigpaulo, but I have actually noticed an INCREASE in MPG after switching both of my GM 60 degree V6 engines over to GC. I only wish I could run CG in my "toy".

With GC, my 2.8 30v gets one mpg better and is more smooth and quite than Mobil-1 0w-40. I really don't understand it because you would think a thicker oil would be more quite.

I believe what he said was that GC is quieter than M1 0W-40 and you would think that the M1 would be quieter since it is thicker.
