I changed my oil recently and I have learned what oil not to buy again

i have heard that todays oils might as well be synthetics. With that said i still run M1 syn with dexos 5w-30 in my truck.

Most of the premium oils today use synthetic additives and are highly refined compared to oils 10 years ago. Additive were usually the first to go in oil, now they basically remain as long as the oil does.

The Quaker State you bought, was it the conventional green bottle, or was it their synthetic?

 

I've been using Quaker State synthetic for 3 plus years and it is one of the best and quietest oils in all of the engines in which I've ever used it. As far as Quaker State being garbage, it is owned by Shell. Recently PQIA tested some of the top name synthetic oils. Based on Noack volatility (the percent of burnoff) The cold flow properties (viscosity at -30----lower #'s are better) the amount of zinc (wear additive) etc. I don't see how anyone can call it junk. It's numbers are as good or better than Mobil 1, Royal Purple, Amsoil OE, and many other name brands. It is almost identical to Pennzoil Platinum which is also owned by Shell. Many used oil analysis reports at bobistheoilguy indicate that it is one of the best choices for syns while being a bargain to boot.

If you aren't happy with Quaker State, obviously that's ok. It's your money and you should spend it on what makes you happy. There are lots of other good choices out there, but in my humble opinion the numbers show that there aren't many significantly better. It's not 1970-something and this ain't daddy's Quaker State anymore.

Took the words right out of my mouth... MY Truck sees only Pennzoil Platinum or Quaker state Ultimate Durability, both excellent oils and are very hard to beat...

Let me put it this way. Pennzoil and Quaker State Conventional are garbage. I know for a fact that Pennzoil is because every engine I've seen it used in ends up full of sludge, and they had the oil changed regularly. I have heard from other people that Quaker State isn't much better. Now as for the Synthetics I'm not sure, but I would think they are way better because mostly synthetics are. I still wouldn't use them though, but that's just me. I'm a Valvoline, Castrol, or Mobil 1 guy

[texansilverado]

Haha.... For a second I thought you were going to say you changed your oil and there was no oil and you had just finished a long road trip. And while driving your truck with no oil you never got a lower oil light or oil pressure warning.......reminded me of a story, but lets not bring that up.....somebody will post the link and raise the post from the grave ..... Lolol

Dexos1 is a synthetic blend oil.

I disagree, the Mobil 1 Extended Performance is a FULL synthetic oil, and is Dexos 1 approved. Dexos 1 is just a standard that GM imposed for using a high quality oil, I find that the approved oil is 5W/30 weight.

 

It also lets GM void your warrenty for engine failure, if they can trace it back to the oil you used that caused the failure.

 

RIGHT ON GM!!!!!!

The brand of oil you use has nothing to do with the ticking you have on cold start. My '11 6.2 did it (28k miles when I traded it in las week) and my '13 does it (380 miles currently). It's caused by bs cheap parts, the lifters especially, period. I ran Dexos and Amsoil in my '11 with puralator, AC Delco and Amsoil filters with 0 change. It always made noise.

I believe that GM parts are of high quality, the problem being dis similar metals that are used (i.e. aluminum block, steel sleeves between block and piston).

 

My 2001 Z28 (Sara) 5.7L (348 c.i.) Gen III LS1 has a tick @ startup, until warm, the generic name given to this is called "piston slap".

That's not the noise my trucks have had. My '98 had that and it certainly wasn't a tick.

let's see if it gets quieter now...ouch it's a hot oil change!

 

I picked up some Honda Genuine synthetic blend 5w30 from work today

Sorry, forgot to say that the AC Delco Dexos1 oil is a blend, semi synthetic, the oil you get from the GM dealership.

[Davidsingletary]

I'm not bashing Quaker State or any other brands, it was on sale (which may be mistakenly perceived as "cheap" or of "lesser quality")

And I have no credentials, proof, or knowledge of what oils are "good" or "best"

 

All I have is an observation.

That being after I changed my oil from Penzoil to a, new-to-me brand: Quaker State, I had a much louder and more frequent ticking noise that I suspect is the "normal"

ticking sounds that these engines are notorious for.

Call it piston slap, lifters, etc...I personally heard this noise before this particular oil change, and was used to it. But now it is louder and longer occuring

 

There is a possibility that there is no relation between Quaker State, or Band-X oil, and more engine noise.

There is also a possibility that changing the variables in this experiment will yield different results: Example: introduce different brand or numbered oil --> get less noise

 

 

That is all I am doing

 

Swapping from Quaker State 10w30 to Honda Genuine Synthetic Blend 5w30 to see what happens

(Using an AC Delco filter)

[Big D's H D]

Add aQt of Lucas oil stabilizer in place of the 6th qt. when you change Back to the Oil that worked best for you and your engine will never TICK again! I used this in a V6 S-10 that started to have a constant lifter tick, and a few days later the tick was gone and never came back,250,000 miles on the clock the stuff is Great! try it and you'll see ..... good luck

From the owners manual:

 

Use only engine oil licensed to the dexos1 specfication, or equivalent, of

the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is

recommended. See Engine Oil on page 10‑6.

Don't ya just love the word Equivalent? There are some oils out there that meet the exact same spec (GF-5) as required by the Dexos requirement. The companies have not, at this time anyway, paid GM for the licensing of the word Dexos. So if I used Amsoil oil that meets the GF-5 spec I have met "equivalent" as noted in my 2013 owner's manual.

And as a retired GM engineer, who worked for many years in Service engineering. I know that if GM pushed it and you pushed back with receipts showing the equivalent oil was used, there would be no problem.

I'm not trying to argue, but the old Pennzoil/Quaker State paraffin wax, sludge stories seem to never die. I really think back in the day when no conventional oil was anywhere near the quality of current oils and PCV systems were poorly designed or neglected that there were lots of motors with sludge problems, with any brand. Since Pennzoil was then and is still currently the #1 selling conventional oil brand and since more cars had it in the crankcase it got the rep for sludge issues. Read FAQ #1.

Anyway, like I said Pennzoil and Quaker State are both currently owned by Shell Oil. Shell's synthetics are top notch, and facing the wrath of brand loyalists, are in my opinion a step above Mobil 1. (No I don't work for Shell)

 

But just so folks can compare the conventional/dino oils, here are tests from 2011 on SN rated name brand conventional oils again by the folks a PQIA. Look at Pennzoil in comparison to the others. (I believe Pennzoil conventional is a step above Quaker State myself.) So to the original poster Pennzoil is better on paper as well in your experience. Notice the levels of moly and zinc. Also the beginning level of additives measured at 8.3 TBN (total base number) beats them all. On the sludge front, both Pennzoil and Quaker State have the highest levels of nitrogen which is a sludge dispersant/detergent.

 

In the 2011 and later trucks the dexos spec hasn't been (can't be?) met by a conventional oil. Dexos speced oils are either semi-syn or syn, so I can't use a conventional and meet the Dexos spec for my warranty purposes. But, if I were looking for a conventional oil, it would be Pennzoil. The others are good, but just not quite as good.
