I got the update for my '24 Tiguan a few days ago also. It borked the dash lighting. In daylight, even on a full cloudy day, the dash lights are on full bright and do not respond to the level setting in the controls. At night or in the garage they revert to the control setting. The dash is OK at...

The press release mentions 100% injector deposit removal using GDI industry standard test methodology. I'd bet a beer and a donut that this is their TOP TIER+ additive. Ed

I agree, Lake's contributions are a net positive. I would love to see what his content would be if he were unfettered by the need to pander to YouTube's algorithms, lowest common denominator audience, and conflict of interest running a business selling UOAs. Ed

Here's the application notes from ThermoFisher for running ASTM D5185 on one of their ICP-OES instruments. I've quoted the section of the Scope that illustrates why so many of us harp on the limitations of the methodology. Here it is, straight from a manufacturer of an instrument used for the...

And yet they are too big to flow through the tolerances of a Toyota engine. Ed

I started to change the plugs on my 2008 Legacy GT. Removed the airbox and ran into some what looked like emission related bits that looked quite complicated to remove. I realized that I would need the service manual to proceed. I reinstalled the airbox and took it to my trusted, independent...

Amazon is a good source. A quick search turned up Miller's Oil, which has the proper SAE 90 for your car or your choice of SAE 30, 40, or 50 ND oils. SAE 40 overlaps the lower end of SAE 90 gear oil and SAE 50 overlaps the upper end of SAE 90 gear oil. Miller's on Amazon There are many options...

I found it interesting that the main bearing girdle has steel inserts. The top shell of the main bearing seats in the aluminum block. The bottom shell in steel. Aluminum has roughly twice the linear expansion coefficient of steel. It seems that would introduce an issue that would have to be...

Those aren't sold by Walmart. It's a third party selling and shipping. You're probably paying $10 for the filter and $12 for the free shipping. Ed

Ultimately that should fall on the poster. If someone doesn't know enough about a subject to know if AI is giving a nonsense answer, they shouldn't be answering the question. A couple of weeks ago I needed to confirm a repair procedure. I knew the answer, but as I often do, I did a search...

The heat of vaporization cools the liquid also, exacerbating the freezing on the windshield issue. Ed

In 1985 I put together a paper explaining the various attributes of motor oils and tables of oil specifications. This was before the WWW. You had to pick up the data sheets from the local distributors or request them from the various oil companies. I was curious as to what Z7 was and called...

I got the same too good to be true vibe from the website too. I plugged the address they give on the "store directory" page into Google maps. Not confidence inspiring. The carpet does not match the drapes, as it were. 112 Frederick Ave, Rockville, MD 20850 Unit F Unit F is the one with the...

You're getting a $40K EV. The extra $600K is for the mandatory yellow painted caliper option. I kind of liked the interior at first glance. The more I look at it, the less I like it. It looks like it was assembled from a Lego kit. Just a bunch of pieces stuck on. Ed

He did not provide data that showed that particle counts are lower not changing the filter than if the filter had been changed at every OCI. He has nothing to base any claims on. A sample size of one representing half of the experiment is speculation, not science. Ed
