Yeah and it's also normal to replace the timing chain every 45-60k miles LOL! They need to de-carbon the rings and pray that fixes it, issue is they still own an EA888 and that engine family is just trash tier IMO. I hate them

 

Yeah 100%, I use an exploit at AutoZone to get oil for the Audis and the LS460 that would normally be $16 a quart for $43 for 5 plus a free filter. Ends up feeding my supply of normal filters for my other cars and I get the needed oil for a car for "only" $86/129 depending on if it's one of the V8s or the W12s. Damn W12s all take 12.2 quarts each and there is a swarm of them now

 

Every car I have owned with the (2UR-GSE) I always get oil changes done every 5k-6k miles using 5W-30 Full Synthetic. I will never follow the 10k miles interval oil change even on my '25 Pilot.

 

I had my oil changed for the first time since buying the 540i after about 6k miles. Would have done 5 but couldn't get to it

The truck gets done when the computer tells me to, about 10k or 12 months whichever comes first. It's NA and port injected only. It'll be fine.

 

I don't think the engine family is trash tier, I think the manufacture-recommended intervals is what causes these engines to have issues.

On my 2013 allroad with the EA888, I'm at 174k miles on the original chain (clicks ~4) and original turbo, burn a quart right by when I change the oil every 5k. When I bought the car with 97k miles it was burning like a MF every 1,500-2000 miles, and all of these issues are due to the 10k oil change intervals.

 

The 2UZ motor is rated for 6K outside of North America. 5K in the US. I once went 2 years without an oil change in my UZ. Driving style is still very important as a factor too. In defence of the Land Cruiser 3UR, nobody really knows the history of the service or driving style. CCN already did one repair, maybe he did it poorly. A 200K is a lot of miles.

 

I just really hate how many I've worked on. They never come to me in good health and cam adaption angles are always 4-5* on the "good" ones. Contrast this to the 4.2 RS5 V8 easily able to get 200k miles and have like 1.2-2* max and no other real issues at all....

 

Yeah, I see so many people have issues with the EA888s even on the new ones still. All because of the service intervals Audi recommends imo.

 

I have(had) 3 vehicles, currently have 2 over 100k that gets nothing less than 10k oil changes performed by yours truly. Then I send in the old oil to the recycle tank in the back at auto zone. I don’t try to be smarter than the engineers who designed them. I don’t pamper my vehicles and they don’t live in service bays.

 

I agree. I just follow what the spec intervals say.

 

You are likely correct but all they care about (and this applies to really ANY carmaker) is that the car lasts warranty and has the cheapest possible advertised cost of ownership. I've just never seen one well taken care of since those owners tend to really never need to visit me....

I have a few ultra high mile Germans who use me but they all maintain properly so there has never been real issues. Just added a 2011 A8 4.2 to my list of customers and his car had 198k when we brought me to inspect it. Had a perfect history but I still struggled to believe how good it was, needed a CV boot re-clamp and trans pan re-TQ and that was it. Literally everything works

 

The engineers will tell you the same things we are. The only reason they recommend those intervals are to advertise lower TCO and for environmental reasons.

Same reason the cost unlimited cars have totally different service recommendations, my Phaeton W12 says it wants trans fluid every 20k, diffs every 40k, oil every 5k, and spark plugs every 60k. The V8 version of the car says lifetime for everything but plugs at 120k....

Same story with my D4s, the W12 has mostly the same driveline hardware as an S8 but it has more severe interval recommendations because they don't care at all at that point that they may scare someone away with higher cost of ownership on a car that is $260k in todays money. The only thing they have the same interval on is the TVD at 60k miles for the actuation fluid, crown diff, front/rear diff, and trans all get half the miles on the W12. The ironic part is my plugs at 100k looked fine vs the V8 eating them alive at 40k miles




The LS460 even has different recommendations stateside vs foreign markets and the 07 US cars have oil and spark plug intervals that are HALF the 08+ cars with zero part number or engine changes. It was again done only for TCO reasons

 

Its not about being smarter than the engineers, its about understanding why the engineers suggested 10k OCIs. Its about balancing the demands of maintenance with the projected lifespan of the vehicle. Car will last 100k miles with 10k OCIs...will it last 200k? 300k? Most people don't care...but if you are somebody who wants to get 200k....300k out of an engine...even the engineers say 10k OCIs are a bad idea.

Don't listen to me, listen to this guy who engineered the Nissan GTR as he's interviewed by another automotive engineer:



For instance we know the UR engines burn oil as they age and they experience this failure discussed above...in my case the oil separators are known to clog and that leads to that incredibly painful and expensive valve cover gasket repair I dealt with at 50k miles...that was 24 hours of labor, the car was off the road for a week and if I were paying the cost was $9,000. If doing an OCI every 5k miles could avoid that...why wouldn't I do that?

If you're not going to keep it long term, and you don't have a specific scenario like I did with the oil separator issue...then sure just do 10k OCIs.

 

Striker and SW are correct, I strongly believe it's to get the car through the warranty period and then some. There are so many mechanics that have done teardowns that say this same thing. You definitely can reach 200k following the 10k intervals, but you don't actually know the wear on your engine unless you stick a scope down there or do a teardown. Your car may run fine, but doesn't mean there is no excess wear you just don't know about.

To many people who work on cars have told me 10k is not a good idea. 10k oil changes are very convenient comparing to having to take your car in at 5k and it's definitely a selling point. What I would do if I were you is send one of your samples to a lab like Blackstone and have them do an analysis. If they find no excess wear and the oil remains in good condition, then you know 10k is fine

 

Jaguar Land Rover has recommended oil change intervals of 2 years or 21,000 miles. It's like they want to live up to their reputation.
