Modern engines bear little resemblance to engines of even 20 years ago. Oils today bear little resemblance to oils of even 20 years ago. DO NOT UNDER ANY CIRCUMSTANCES EXPECT TECHNIQUES THAT WORKED *THEN* TO BE HELPFUL TODAY!!!
Blackstone ran tests on vintage oils. Their conclusion was:
So that’s the end of our series. A lot of thought goes into making oil, and that’s been the case for many decades now. We’ve poked some fun at the way oil companies sell their products, but heck, they’ve got to say something. We stand by our statement that “oil is oil” and in the end, it doesn’t make a lot of difference what you decide to use. Through all the years and all the permuta-tions and configurations of oil and oil additives, the crude (and now, synthetic) stuff has kept cars running since Henry Ford did his thing more than 100 years ago. Buy what suits your vehicle and your wallet -- not what anyone else says you should use!
