@Tinkertech I agree with you 100% !

Kodpkd won’t rest until everyone agrees to run 0w-40 and the pf64 oil filter. Oh and that 0w means 0 degrees Celsius.

 

lol lol 😆 😂 🤣

Getting that post count up..... lol lol

Yes the 0 is degrees and the W is for Winter. Nope. There are lots of oil filters you can use, they just have to have the 22 PSI bypass. NOT 15 psi and NOT 35 PSI. It's kind of a technical thing on how the engine is designed. It just bothers me when people have such a wonderful car and don't have the knowledge, or are to cheap, to care for it correctly. I really don't care what you do to your own car, but what I don't like is when misinformation is spread as fact. People come here for facts.
Straight from the current 2019 manual. Kind of hard to understand!
"Use SAE 0W-40 viscosity grade engine oil"
AND they changed the Dexos oil from Dexos1 to Dexos R.

 

I think we can agree with you on the filter but you’re just wrong on the oil man. Give it up. Use the 0w-40 if you want to but just please stop spreading your misinformation and pleading everyone to convert.

 

No. 0 denotes sufficient ability to flow on initial cold start-up tested down to -40°. See the following and you can go to 2:50 if you don't want to watch the whole thing. Pay attention to the column labeled "Low Temp. Pumping Viscosity.

 

Man u just need to give it up ... so many have told you the reason WHY GM changed the spec and by the way , this reason is published ..... and yet you continue to press your point of view and say everybody else is wrong . So i gues that on my on my 2015 , which I have changed the oil religiously , using the old spec, and all the other owners out there, including your car ..... that did the same .... we should be worried..., I think not ...

Look you are entited to your opnion and we are entitled to ours

Now please ... step away from the keyboard ... step far away from the keyboard ..... resist the urge to reply ....

Deleting just your posts from this thread would eliminate 100% of the misinformation in this thread.

Even clinging to this "zero is degrees" thing is getting ridiculous.

 

It is a bit strange to wish to eliminate the posts of the guy who started this thread in the first place. Although I don't agree with a number of statements he made, there is some truth in what he stated. GM recommends 0W40 now and we know the reason they told us.
We don't know if this is the only reason.
Even though the recommended 0W40 might include viscosity modifiers, it does not automatically mean a 5W30 oil includes less viscisity modifiers.
There are big differences in the viscosity index of different base oils, and depending on the base oil used, a 5W30 oil might inculde more viscosity modifiers than a 0W40 oil.
But even if there are more viscosity modifiers, oils that are Dexos certified need to stay in grade for the time of use. That means a 0W40 oil at the moment of change has a wider viscosity spread than a fresh 5W30 oil.
Does that mean everybody needs to use a 0W40 oil ?
No, 5W30 oils were used for many years and served many people well.
But if you own an early year Z06 (with the thin main rad and without aux cooler), I would certainly use a 0W40 oil.
If you live in a cold climate and also drive during winter, I would certainly use a 0Wx oil.
If you live in a hot climate and hammer your car regularily, I would certainly use a xW40 oil.
Personally I own a Z51 and hammer my car frequently, but I have retrofitted the thick main rad AND the aux cooler. So my oil never exceeds 220° F and I never drive in winter.
Therefore I use a 5W30 oil, but I would also not hestitate to use a 0W40, it is just not required.

When it comes to the filter, the statements of kodpkd are relevant. There is a very good reason to only use filters with the corrent opening pressure and he never said to only use the AC Delco filter, he said to use a filter with the correct opening pressure.
