Excellent thanks guys!!

In my gasoline engine BMW delaer uses a fuel cleaner every time they did a service (well at least here in SOuth Florida they do), it is exactly the same as Techron...
THe only gas I put in my cars are Chevron and Shell... and as far as Dieels there is only 1 option...

Thanks
