Get better mileage
The car had 36,600 miles. I also thought I would see better mileage.
I then added something I used to use in my 300 E 2.6 trade in. It's called Ventil Sauber (valve clean) then went on a 2100 mile trip. My gas mileage went up to an average of 29 miles to the gallon averaging 72 miles / hour. The highest I saw was driving from Flagstaff AZ. to Laughlin NV. averaging 74 miles / hour, and it was 31.5 / gallon.
I now have 42,000 miles on the car and get 17 to 19 in town and 27 to 29 highway.
Has anyone else tried this Valve Cleaner?
I bought it from Performance Products made by Lubro Moly.
Love this car!!!

Lubro Moly also makes a crankcase cleaner that I use at every oil change. It removes combustion by-products that don't suspend in the oil easily. It also thins the oil a bit to make extraction through the dipstick easier.
If an engine has been neglected and the crankcase is covered in goop, Bilstein (same as the shocks) makes a machine that flushes the entire oil system with a heated solvent. For the fastidious it is worth the hundred bucks to have a sparkling clean bottom end.
