Thanks for sharing. What's the mileage on the engine, what were the oil change intervals, what oils were used?

Oil companies with approvals are publishing that their additives and blending specifications meet the OEM specifications. They consequently don't need to publish anything else. The boutique oil companies do not have approvals, so how do you know what is or isn't in there, what has or hasn't...

Oil companies with approvals are publishing they meet the OEM specifications. That doesn't just include the majors, but also smaller ones like Motul, Liquimoly, Ravenol, etc. You are talking about extending oci's. I am talking about piston/liner wear, camshaft/tappet wear, piston deposits, etc...

That's right, the additive packages and blending requirements have passed the OEM engine tests. And when an oil blender adheres to those they get the approval. And the customer knows they have passed the minimum requirements (which in the case of euro approvals is a pretty high specification of...

They do provide that information by virtue of passing all the required tests to obtain the OEM approvals. And they're not charging extra $$ for their products.

Like I said in the first post, engine tests not bench tests. Bench tests are useful but have a limit on the insights they provide, and is the reason OEM approvals require a battery of fired-engine tests. This applies not only to lubricants and automotive, but almost any product in any industry...

That's right.

That's fine, however if anyone is charging a premium for their product over one's with OEM approvals, I want proof that their "enhanced" additives, base oils, etc are providing enhanced performance in the relevant engine tests.

We are a 1 ICE, 1 EV household. I work from home and my wife commutes to work about 10 miles away. Having one of each is working well and in the future when the vehicles+infrastructure have matured more, both of us will have EV's as daily drivers and ICE for a third car. EV's frankly are much...

+1 for laser. Switched 15 years ago and haven't looked back.

There are three possibilities: 1. BS testing error 2. Mechanical issue 3. No mech issue and this sample is representative of this vehicle's usage If #3, it's a no brainer to switch to a 30wt oil (probably euro 30wt).

The wear metals look similar between the two labs but those are substantially different results on viscosity and additives. Is either one ISO? The level of additive depletion indicated in the BS report seems hard to believe for a 1k mile run.

I've had a number of routers over the years from most of the major manufacturers. The best experience in terms of reliability (not having to mess around with it) and performance (coverage), was the Google Nest mesh wifi system. Worked better than router+extender set ups and you can easily scale...

I'm amazed this discussion has lasted 6 pages. What's the argument to be made for not doing a break-in oil change? The risk is completely asymmetrical with regards to engine wear and we are talking about the cost of one extra oil change over the life of the vehicle.

I have the Audi 3.0 supercharged engine in my 2013 Q5. These engines have a common start-up timing chain tensioner rattle and mine's done it most of it's whole life. It's ok initially after an oil change and starts a few thousand miles into the oci when the viscosity drops. Usually occurred...
