My dad had a Cadillac Coupe DeVille, I think 1959…

Mistake of '58: The GM Chromemobiles and Far Out '59s

A classic car connaisseur tells the story of General Motors misstep in 1958. The future wasn’t about chrome, but about tailfins. This video goes deep into the design process that ulitmalety resulted in the most space age cars ever made… the 1959 Chevrolet, Pontiac, Oldsmobile, Buick and Cadillac!

Do you really want an ICE car? The complexity of a modern gasoline engine is just unbelievable! This video is not to criticize Audi but to show the reality of the end of life of the ICE age.

SLUDGED To Death: Tearing Down My SEIZED Audi 3.9T Engine

The engine out of my 2011 Audi A6 has been lurking in the shop for awhile now. I decided is was time to tear it down and figure out what caused it to seize up in the car. I expected it was a headgasket issue as the exhaust was full of coolant when we pulled it apart. As I tore the engine down it seemed like there was no issue with the headgasket. All I found was sludge, and it only got worse as we went, the oil looked like jello in the oil passages. The sludge was so bad it caused the engine to seize.

Some engines seem prone to that issue. A few years ago, Toyotas were notorious for sludge. A VW 1.8 several years ago sludged up badly too.

Engine Sludge in Toyota Engines


Hyundai/Kia have become notorious for seized engines in recent years. The excuses from corporate may change, but the result is always the same, in both their Theta II and Nu series engines: bearing knock, piston slap, overheating, then failure to proceed.


I think all of that, the jellied oil & sludge could have been easily prevented by the use of esthetic oils, Amsoil, Mobil 1, or even one of the blends…

Way back, I recall a 1976 Popular Science magazine article on synthetics, made me a believer back then, but I was still doing my own changes, regular oil was cheap… But losing an engine in the '90s completed my conversion. Only synthetics from then on…


Nice to see someone saved their copy!

VAG has used synthetic oil for a number of years. My 2014 VW specs Castrol synthetic. Probably the same for the Audi in the OP.

“Synthetic” oil is a marketing term. iirc, Mobil 1 is about the only true synthetic. Others, like the expen$ive Castrol that goes in my sled, are made from petroleum.

What prevents sludge? Frequent oil changes, and long, fast, runs down the highway. When the snow finally melts in April, I get the oil changed in my sled, even though it may only have 3-5,000 miles on it, vs VW’s 10,000 mile recommendation, because it’s been in there all winter, with it’s short, cold, drives, while accumulating condensation and piston blowby.





has a good chance of living on in textbook equivalents for centuries, if humanity manages to live on. Wow. What fun! (though I did feel of twinge of voyeur guilt)<.

I guess I should re-read my posts, esthetic, indeed! Synthetic here, at least my prior mechanic was Amsoil, I buy a case of Mobil 1 via Costco for top ups…

I tried a synthetic in my Yamaha XT500 thumper, but it shares the lube with the transmission, and it wasn’t right, made it feel harsh when shifting, so I went back to my old standby, Valvoline, One day someone should change it, I suppose… Need to find a buyer…

Anyway, I tend to push limits, synthetics seem to let that happen…
