Have any one tried this on our E60?
The concentrate one is more expensive than the pro gard.
From what I read before the concentrate one has 2X the amt of Techron than the Pro Gard one.
Costco sells the progard for $15 for 6 bottles.
I usually just use 2 bottles.

Chevron Techron. I think it's about $8 a bottle to treat 12 gallons. Lot's of other less expensive options on the market, but I generally hear more positive comments across the message boards on Techron.
