I use a lot of Castrol Synthetic!...

Posted by dark_dave56 on May 13, 2022 at 05:40:23:
...but then I used to use a lot of Castrol "dino" oil back before synthetics hit the market in any scale. Of course, I've used a lot of Mobil 1--it was the first major-market synthetic out there.

Synthetics aren't "all-that", either. Lubricants are produced to specifications--viscosity and thermal stability being two "biggies". A highly-refined (distilled--you do realize that refineries are nothing more than huge distillation columns) "dino" oil can meet or exceed the specifications of a synthetic.

Remember ARCO Graphite? My cousin nearly destroyed an engine in a Trans Am with that stuff. It used suspended graphite in the oil to (theoretically) improve lubrication--the oil was black, straight out of the can. If you got it too hot, or didn't change it religiously, the suspending agents for the graphite "broke-down", and the graphite particulates separated out--either resulting in clogged filters, layers of sludge in valve covers, or ultimately becoming an abrasive, rather than lubricant.
