better save the crate .. in 30 years it will be worth a million dollars
10w-60 oil.....didn’t even know that existed.
My 2000 BMW M5 specs 10w-60 synthetic for it's 400hp 5 liter motor, so It's been around for at least twenty years. Before they discontinued it, the BMW oil was nearly $15/liter. Liqui-Moly makes a nice version, but apparently they aren't all the same. In a $30k motor, I'd be running exactly what they specify.
Remember in the 80’s when it was discovered that USUALLY when an engine was ‘sludged out’ it was run on 10w-40 conventional with long oil change intervals. Further research determined 10w-40 conventional was most prone to this due to the large amount of viscosity improvers required to reach the 10w-40 designation. VI’s can form sludge when subjected to high temps and old age.
Synthetics don’t require near the amount of VI’s to achieve same.
For that reason I am guessing that EVERY 10w-60 on the market is a synthetic.
