Engine Mechanical problem
1994 BMW 840 V8 Two Wheel Drive Automatic 200k miles
On starting my 840 I have white smoke from the left exhaust. I have found a product called SEAFOAM? Which is a cure?
Also can a MILEAGE MAXX VORTEX GENERATOR increase fuel economy.
My question is do the above products work? Or am I wasting my time trying to improve fuel economy from a V8!
At present I am getting 12mpg in town and 25 on the motorway.
