You seem to be very knowledgeable about tractors. Is this what you do for
a living - a farm hand?

Synthetic only makes economic sense
on engines designed for it

ALL modern engines are designed for it. Sorry, oh for you they are not,
please buy the cheapest and nastiest oil available and run it for 40,000
miles. Please do this.

So now you're talking about only modern cars? Like the 14 year old
Cavaliers you mentioned earlier?
