Thanks for that R and R outage away from the tough stuff. I have to say that my question to Shell would have been in the circumstances where I had him physically up agin a wall.
The oil sellers annoy me. I have done a fair bit of tribology and the best lubricant on the planet is nature's olive oil.
You can "crack" imineral oil all you want..comes nowhere near the mighty olive. I am so glad I am nowhere near Shell, I am very short tempered.
