A-friggin-MEN! This has been my motto for 40 years... The ONE time I fogot it I ended up with a motor going though a quart of oil every 600 miles! NO THANK YOU! NEVER, EVER AGAIN!!!

My 2020 2SS is getting an oil AND Diff fluid change at 500 miles, 1,500 mile and 4,500 miles... Does it REALLY need it for a non-tracked car??? Probably not, but it is the most conservative maintenance schedule I could find and the $300 or so investment is WELL worth it to protect my $50k car... ABSOLUTELY!!!

it says it meets the spec its fine. they had to pay GM alot of money to put that label on there oil.

So, re-read what you just stated. "Just because an oil meets the dexos cert it has little to do with the quality. It just means it passed GM's test.

If it passed the test, it does have something to do with the quality, because, it, uh, passed the test, right? And that means it can be safely used in that motor with no adverse effects, huh?

Do you have any comparison tests I can read? Until then, they all meet the same minimum standard set by the manufacturer. And, even AFTER I read it, they ALL meet the minimum standard set by the manufacturer.

Why do I need an oil filter that lasts 10K when I change my oil every 5k? As long as the filter performs at the manufacturers' specs is what is necessary.

Do I need a better filter media at the expense of oil volume and pressure?
Would that require a larger filter to hold more media? What about your fancy super filter plugging up the media quicker and causing the bypass to pop and then I get NO filtration. Or the restrictive media causing a partial bypass. How would that be helpful to engine longevity?

I'd agree with you if the guy were asking if he could put API grade SA 20w non-detergent oil in his ride motor.

Dexros2 oil is Dexros2 oil and will not hurt the motor in any way.

You're right. What was I thinking? Sams oil reigns supreme!

Spend a little time over at BITOG forums. Who knew we were all wasting so much money on uselss oil when "sams club" had my back.

2003 C2500HD and a 2005 K3500

I had an 02 C2500HD and it had them too.

There are 11 total. You could probably cock the tires and see the upper BJ fitting pretty easy.

Sometimes the BJ is tapped and threaded but there is a plug screwed in instead of a zerk. I have only occasionally seen that on brands other than GM though.

But hey, maybe the Sam's Club oil IS "Dexros2"!

Thank you very much, I'll stick with Mobil 1 0W-40 ESP Formula (Dexos2) for my $18.5K engine (factory recommended)

because the molecules are damaged. It wont meet dexos2 spec.

So much wrong with this molecule damage I won't even bother with it.

We have a winner.




There is a lot wrong with a lot of statements in this thread. Dexos 2 is for all the bullshit catalytic converter requirements we got force fed from the last idiot in office under the 2012 EPA mileage mandates.


ANY MOTOR OIL THE MEETS DEXOS 2 SPEC of the proper weight is more than acceptable. Crazy fact, you could run them on non synthetic and your engine would be fine.......


Please for the love of God, go read up on what qualifies as a synthetic nowadays as I could pee in a bucket and whirl a ball in the pee for 3 minutes and qualify.......


Here is the key parts u need to worry about, proper spec per manufacturer(for your warranty) and changing your oil on schedule or earlier. If you're buying boutique BS oil and changing it every 3k miles you're making yourself poorer.


Think of it like this, everyone fawns over the AC Delco filters because they are the "best", same bottom bidding company will be making the next batch which is different from the last batch :-) (I like Baldwins for constitency personally)

i completely forgot about the HD trucks. 1/2 tons dont have any.

I know little to nothing for oil comparisons but I do know that SuperTech Full Synthetic does have the dexos2 label

Seems like all SuperTech oils that are Full Synthetic have the certification now

[SJFGTO]

If it meets the Dexos2 requirement, it is fine for your Camaro. Your engine does not know what brand of motor oil goes into it, that is largely a feel good thing for owners. Yes, different oils have different additive packages and there are some which are likely “better.” But for day to day driving with regular oil and filter changes you’d be hard pressed to see the difference after 50 thousand miles. Have an oil analysis done after an oil change and see what shows up if you are concerned.

If the best you can do to attempt to disprove an argument or fact is a misspelled word....

As far as sticking with Mobil1, it *might* be a "better oil" than Sam's Club oil.
But, the cheaper oil won't hurt your engine since all the minimum specs are met. (Provided you follow recommended drain intervals).

[LT4Greg]

I don’t understand all of this arguing about brands of oil to use. If it is Dexos2 and synthetic then you can use it in your engine! I get flack from my friends about using Valvoline instead of Mobil 1 in my ZL1 but it’s fine to use because of the rating. Also I’m hearing that I should switch to 0W-40 instead of using 5W-30 what the engine is supposed to use unless I’m tracking the car. There is too much grumbling and arguing about oil brands and grades in my opinion! Run the brand/grade of oil you want to use and roll on!

Wow! I did not know that the 1/2 tons did away with them. It's been a while since I was a grease monkey...
