@weaponoffreedom You think it’s funny, yet the literal site operator of BITOG @wwillson and several other mods/proven members have data to back up that 20k is not a pipe dream. All you got is jokes? Telling.
I have no doubt that an oil can, and in fact does last 20k or more. No issue there. But for the normal guy, in severe conditions, changing the oil and filter every 20k is just asking for trouble. Especially after changing to a superior product like HPL.
Read my reply to astro.
Where did anyone mention not opening the hood and/or performing other sensible maintenance operations during a 20k OCI?
also, with todays engines, using a quart per 1000 miles, I'll bet almost any oil could go 20k, with just topping off with fresh fluid.
Its not the oil ability I question, it is the unintended consequences of not checking things that would make me not recommend such a oic. Do youi not understand that. Thought it was pretty clear.
also, most would not be sensible, they are not like us, up on maintenance and such.
I did, in my post of opposition.
Its ok, keep backpedaling. Eventually you’ll get back to the facts that 20k OCIs are possible, and not that unusual, especially when paired with minimal maintenance checks during the OCI.
I wouldn’t make that assumption about consumption.
Not really an assumption as many low friction ring direct injection engine do this, that is what i mean about "todays engines" I have 3 in my work truck fleet, all 6.6 L8T engines and they are all like clockwork, oil users. There are many known complaints about this, and is a known thing. And the like with many other DI newer engines. Not sure about your Tundra, as Toyota is usually and rightfully last to jump on the dumb idea band wagon. My older 6.0 vortec uses 0 oil, and is is run hard.
You think most of todays younger generation will do this, really?
I am not contesting this, I have no doubt that this is true, but the total idea behind it is what I would not recommend. Thought I made this clear.
No I would not, as they are not low friction ring, DI engines.........really you could probably run anything you want in them and they would be fine as they are good to begin with.
No clue, and I aint backpedaling.Its ok, keep backpedaling. Eventually you’ll get back to the facts that 20k OCIs are possible, and not that unusual, especially when paired with minimal maintenance checks during the OCI.
IIRC, @dnewton3 has run somewhere around 15k OCIs on conventional & semi-syn oils for quite some time. I dare you to try to disprove not only his data, but his analysis to support his position.
You’re obviously free to do as you choose, but making up unsupported claims won’t stand for long here. Do you think XOM’s lawyers would expose them to unnecessary litigation with Extended Protection if it wasn’t capable of delivering on its publicly stated performance standards?
I made no claim fella, just oppostion to an idea, with reasons why I do not think it is a good idea for the regular individual to rely on 20k oil changes is all. It seems as though you dont get it. I have an opinion on the subject...........and have stated it. Can you refute my stance? NO, becasue they are all valid points. Never once did I say the oil cant do it, I said the owner should not, there is a big difference.
On the MB - OEM. 10,000 for now.
why not 20k?
Well, that’s over five years on the MBs at their current rate of use. I live in a very humid climate. MB requires 10,000 miles or one year. I’m OK going to a couple years, based on UOA, but five seems excessive.
Low tension rings get blamed a lot on here, by more than just yourself, but there are many engines that use them that don't consume any appreciable amount of oil, Wayne's Pentastar being one.
DI and low fiction I think is a unneeded design, especially when put together in one design.
It's not inherently bad however. BMW's execution appears to be just fine.
