Satyr,

Great post.

I started using Delo 400 about 17 or 18 years ago. Not too long after that I answered an ad about something and it turned out the guy was an oil additive formulation expert and the owner of an additive company.

He asked what oil I use and I told him Delo 400 and his response was a surprised "Really?" I thought he was about to tell me how bad it was, but he started telling me the opposite. He said that it tested as one of the best oils money could buy. I asked him about gas engines as well and his response was a very affirmative "for ANY engine."

I have stuck with it for most everything, but have moved toward synthetic for a few new cars in the family that call for a lighter weight oil.

If anyone were to see the insides of my engines whenever they come apart and examine the wear surfaces, I think they would be sold on the stuff pretty quick.

Have a great day,
