As a side note, those VWs had no oil filter, only a screen attached to a removable plate over a low flow area where GKW would accumulate. The manual reccomended 1000 mile OCIs, but I did 3000 mile "extended" OCIs.


Did you adjust the valves every 3,000 miles like the manual recommended?

Never did adjust the valves, but I had an OCD about plugs, points and the condenser. I adjusted the plugs and points at least once a month and probably changed the condenser every 2 or 3 months. I can't remember now why I would do those things at such short intervals.

Or maybe I do know. I had access to that darned hippie VW manual, whose title I can't remember, and did pretty much everything described in that book, except adjust the valves. Sad thing is that I never owned the book, but would get it from the town library every time I had a problem to correct or, when bored, create.

More on topic, I still use MMO as a gas additive on an irregular basis, altenating it with Lucas UCL. They are both for preventive maintenance so I can't really say they have helped cure an existing problem. Neither has hurt anything that I can determine.
 
Have a '90 Ford Ranger (2.3-liter 4, auto, 130K miles) just bought last year. A few ounces of MMO in the fuel tank fixed a sticky float that had kept the fuel gauge from reading much past half full with a full tank. The gauge reads properly now, and the truck runs better too.
 
I tried both ARX and MMO in my Audi 1.8T...with the most visable results using the MMO! My car had been using the Audi specified extended oil changes on dino oil (which Audi later revised) and is known to cause sludge.
After getting the car and changing the valve cover gasket I noticed there wasn't really any sludge on the top end but quite a bit of varnish. Tried the ARX as the directions stated and noticed a little difference when looking in the engine oil fill. Added MMO for 500 miles before my oil change and the MMO cleaned the varnish off. I still use the MMO every other oil change just incase of any sludge.

My mother, when she was alive, asked her most trusted mechanic if she needed any type of additives, other than the regular oil changes. The mechanic, who later moved up the ranks into management in the dealership where he worked, said that she didn't need to put extra aditives to the oil or gas, just use the oil recommended by the manufacturer, and the type of gasoline recommended for the automobile, and she drove her cars for many, many miles, and years and years with regular maintenance oil change, and what the manufacturer required for the warranty of her cars. Someone bought her last automobile that she owned, and it is still going strong, almost 100,000 miles on it, as of last report.
 
Unless you never do any preventative maintenance at all or slam the car into a solid object at high speed, it's pretty hard not to get 100,000Mi out of almost any car. 300,000Mi would be a little more impressive.

I'm all about running a pint of MMO the last thousand miles of an OCI in a sludged or sludge-prone car. I still put a pint in the last gas tank pre-OCI.

1 part MMO +9 parts MMO works for me.

5.2 liter sump capacity : 10 = 0.52 liter = 1 part

You sure do like your MMO!
 
I dab it behind my ears.

I post about MMO about three times a year. Any more than that would be fish mongering. Besides, I don't profit from pitching MMO, so why would I waste my time talking relentlessly about it all the time?

Bri, I was just talking about myself. I'm sure you just have a real passion for one or the other product, and you must share your excitement with the world.
