Do any of those "super lubricants" such as ProLong really do any good? I already know that they are not recommended for new engines with less than 5,000 miles due to necessary friction during break in.
But in engines past 10K miles, are these products just a waste of money?

In a word...YES!

Just change your oil often and throw in a good fuel injection cleaner to the gas tank every 6 months or so if you do a lot of city driving and be done with it. It has been determined by a lot of different State consumer organizations that those products either do nothing or, even worse, do more harm then good with the by-products they produce in your engine over time

The old saying holds "If its to good to be true..." you know the rest.
Save your money for a good tune-up and what ever you do don't run your engine with just one bottle of prolong in it and no oil

All of these products have lost credibility in my eyes, because invariably they conduct a demonstation on some pushrod motor with no oil and show how it runs perfectly. Well, I wonder:
- What's keeping the metal inside cool (oil does do a big part of this)
- What's opening the valves in that hydraulic-lifter motor with "no" modifications?

Best regards, Michael

How about that Lubro-Moly engine oil additive available in PartsShop? Is that a different kind of additive? Does anybody recommend it?

i've used this lubro-moly lubricant before. i wish my engine could speak out, but have not noticed any real difference in performance or in gas consumption.

so my short answer is NO. YES to frequent oil change.

i've read it somewhere that gas and oil companies have invested tons of dollars in research and development to arrive at their respective products, and to better served the ever demanding needs of consumers and their technologically-advanced machines.

to add any foreign substance to their mix will dilute both formulas, hence, the predicted benefits, if any, will fall short of anticipated outcome.

just my opinion. joel
