Default Internal engine cleaner...

A guy I know works at Oil Can Henry's Told me to come in an check out some new product he's pushing..An internal engine cleaner with cleaning detergents..anyone use these kind of products ??
On the same subject an old trucker I was talking to said he would drain the oil put a new filter on refill the engine oil with tranny fluid..Run the car hard for 15 minutes then drain..Then change everything again..said it cleaned the internals very well.

Let the old trucker do that to his old truck. You don't want to do it to your car.
There is no need to run anything other then motor oil through your engine. No cleaners or flushes are necessary or beneficial and in fact may do more harm than good.
Your car is still fairly new, just keep up with the maintenance and do regular, timely oil changes and your engine will remain clean inside.
And, I wouldn't trust anyone who works at a place called Oil Can Henry's

If you feel it necessary to clean it, I used to drain my oil, refill with a couple quarts of clean oil, idle the engine, then change the oil and filter. I traded my old Escort GT with almost 200k on it having done this at every other oil change since 80k, and with 3k on a change, the oil was always still clear and clean.

Actually, older Miatas DO seem to benefit from certain cleaners/flushes. A close relative of the old trucker ATF method has been used successfully by a number of people on miata.net. A less drastic treatment, auto-RX (www.auto-rx.com), seems to have gotten rid of the startup HLA noise on my 100k Miata. The theory is that the tiny oil passages in the HLAs can get clogged up over time with varnishes and other deposits. Obviously, frequent changes with synthetic oil should minimize this buildup, but it does exist on many Miatas (HLA noise is one of the alltime top topics on miata.net).
OTOH, if whatever treatment you try dislodges a *bigger* chunk of stuff, it could block an oil passage and lead to serious damage or death of your engine, so you need to be pretty sure of the diagnosis and know the potential drawbacks before trying one of these "last-gasp" type of treatments.

Hydraulic Lash Adjusters -- the height is adjusted by pressurizing the insides with oil; since the passages are narrow, deposits on them can limit the oil flow into them, resulting in a "ticking" noise.
