[split] My BMW 540i makeover thread - Engine flush discussion

All the petrol sold in CT (with the exception maybe of Sasol) comes from one place - Caltex Refinery. It all comes out of one big tank or tanks. The additives are then added in at the time it is loaded into the petrol tankers. I've seen it done.

I dont believe a thing the petrol companies say.
