I would like you to address the various concoctions like system flushes, Auto-Rx, Fuel Power, and all these "fix-in-a-bottle" additives that we on this forum seem to gravitate to.
Do you recommend them ? Or simply put, is the new API/SM/GF-4 oil's sufficient to keep today's engines running without all the extra bottles of 'stuff' ?
I'd offer to say that most on this forum keep their cars running in a well maintained form, but have to ask are we really only moving our lubrication from 99.1% perfect (before flush) to 99.5% (after flush)...so why go through all that nonsense......right ?
While we have rinse phases, cleaning phases etc...are just fooling ourselves and if we say dumped in fresh new oil and say did a 1500 OCI that we'd get the same results......
Your thoughts.......

Personally, I have yet to ever see any of the snake oil additives and crap do anything other than relocate your money to another persons pocket. If someone is talking it up they must be selling it.

Nope, not selling it, IN FACT paid a lot more to have it shipped to Canada. Ask him if he is even used it, or is he just stated blind opinion?
Probably so.....

How old are these engines? What year and model?
No real info = pure opinion.

GF4 oils have only been out for the last year. So now you are saying that if you do an oil change now, it will clear up the 10 years worth of varnish??? MAybe after another 50,000 miles it will.
Talk about misguided information. GF4 oils were only recently released and you are saying that they will clean an engine with 150,000 miles on it.
That is completely wrong.

I also get to see a lot of field engines in teardown reviews and there is no problem with sludge and buildup in any of the engines I see.

If that is the case one might make a case for a crank case "flush" I suppose....but by the time you knew about it the damage was probably already done. And, in any case, some long trip driving with fresh oil would clean it out anyway.

So he warrents the use of a kerosene flush, but not the use of Auto-RX?
Ummmmmmmmm....ok.......yeesh

Pure opinion with no evidence at all. How about the lot that have working PCV systems and they have varnish and sludge?

Imagine...... How does using Auto-RX for cleaning an older engine have anything to do with building a 440+HP engine???!!! That's right, it has no bearing.
What kind of argument is that?
Everyone, go to here and look at the people using Auto-RX:

Not only are people using it, but they are happy using it too.
Here is a story of a documented Auto-RX test.
