No. Certifications determine a performance floor. You could run all 4 oils in separate engines for say 250k miles, and you would be hard-pressed to ever determine any statistically significant difference in any wear metric or performance measurement between the oils.
I believe the esp has the most certifications.
Even if they are “flat tappet” it’s not the same as an old school flat tappet Chevy small block or something like that. Yours would not need a high zinc oil, buuut zddp is good for more than a camshaft, it’s can be beneficial for other parts of an engine as well, like main bearing, valve stems,etc. although zddp may not be necessary, in my modern good engines “the ones that aren’t in some old beater” I like to use redline oil which has all the “good stuff”. I will say tho that I have had zero issues running pennzoil ultra platinum or any other “regular” oil when I have used them.
Now we drift and tide into oil filters and worries over bypass design.
Nope
The one time I saw a car generating a catalyst efficiency code it was consuming in excess of 1 quart per 500 miles.
This is a forum to ask questions, no? That is why I signed up here. If it is not okay to ask question then i don’t even know why I joined.
Why you joined is up to you. But if you’re changing topics mid-thread then start a new thread in the correct forum.
No this isn’t about the oil filter question. I’m asking why do all my questions bother you. This is what a forum is for. If you don’t like all the question than maybe you yourself shouldn’t have joined here either. Or you could have ignored my questions. Instead of being all arrogant and condescending.
Thank you. I’ve seen you, overkill, and others mention before that the consumption has to be pretty drastic for it to make a difference.
Probably before you ask multiple questions you can use the search engine and learn, do you job before asking. Than you can find that this question has an answer or 99% close to yours. I’m a little surprised that too many bittogers has the patience and time to spend, nice forum.
As terrible as that sounds, it's still only 0.064 ounces of oil per mile. Way less than a 2 stroke
You may need thicker skin to be here; don't get discouraged. There's plenty of good info and good people here. It seems kschachn usually has good intentions; getting people to realize when they're making assumptions that could get them into trouble...
Well it did affect other things as well:As terrible as that sounds, it's still only 0.064 ounces of oil per mile. Way less than a 2 stroke
Oh I'm not discounting the damage that a poorly designed engine can generate. Trying to bring some reality of measurements to those who say "Oh I lost 1/4 of a quart over a 10k OCI, this oil is garbage" people.
I don’t really know exactly how bad the consumption was. But I rebuilt the engine for the person, that’s a long story.
