Well, I found out today I have good news and bad new. Good news is the MPG I experienced doing 80-85 is fairly normal.

I was informed by MB tech that their is nothing wrong with my car. He told me I was due a major service since the last was performed at 166K and it now has 184K.

This service includes ALL fluids and filters in the car and valve adjustment for under $400. Seem very reasonable given the cost of fluids and filters and he has been doing the work on this very car since 40K. Getting a nice very documented package from him about everything ever done. Very well maintained.

Here is something for you oil gurus. This machine has had a steady diet of Kendall 20-50 all its life. Injectors were pop test at 144K and all but one were in good condition. I have been told he has put ATF in fuel every 3 tank and swears by it to lube the injectors. He recommended an additative called Fuel On?? Anyone hear of this?

Steering is loose at higher speeds. I can move the steering with no change in direction. Is this gearbox or maybe ball joints and bushings?

And here is one that will blow everyone away. I ask him about washing the engine. He told me he does this regularly by using a degreaser call purple. Spays it on and CAR WASHES it off both in hot and cold modes and has NEVER in 20 years ever had a problem. The only caution he had was regarding the intake hose. Told me to be extremely careful no water got in this.

First time in my life I had to go search for Diesel sites in my hometown of Fort Walton Beach. It was an experience. Seems I have three choices. Local dealers Amoco and Chevron. Or a 20 mile hike to I-10 to get truck stop quality.

I was also told NOT to change motor oils. I really wanted to change to Chevron Delco but I am told the cleaner could do things to this high mileage motor that could be bad. Anyone had any bad experiences changing oil brands? Would be nice to hear from you.

My project continues.

Later all,

David
