I know a few people who have tryed this, it really works, and it's cheap.

I tried Z-Maxx in mine, and there does seem to be a little more engine response. But on another note, I rubbed down the top of my welding table with it after heating it up real good with a space heater and there hasn't been a lick of rust on it for three years!

We use that chevron stuff too sometimes. Not sure that it works but we go through a fair amount of it.

The local Ford dealer recommended it for my wife's Mustang. Seems to do the job.

Nothing to it I can see.
No failures breaking in new cams, no cold start wear beyond what you normally see.

Just a marketing ploy by the guys still pumping zinc in their oils.
I can't verify that there are significant issues with the lack of ZDDP...but, can say that when I emailed the major oil manufacturers, they all indicated that they have recently (in the last couple years) have significantly reduced the amount...but "it should still be safe for flat tappet engines". Personally, it is worth an extra $2 an oil change to add a little cushion...

I was one of the many people who developed a lifter tick after an oil change. I just delt with it for a month or two hoping it would go away. Then after reading about people using Marvel I gave it a shot. What a difference! Ticking went away and all is good! I realize most of the "Mechanic in a bottle" stuff is just a short term fix though.

I use Rotella T oil in all my vehicles (dirt bikes too). I have noticed Rotella really cleans out the motor. Especially on a neglected motor like my 27 year old 258.

I recently decided to try the high mileage oil in my wife's 120k mile truck. I don't see any difference but supposedly it helps with old seals so I figure what the heck.

I use Rotella oil and tried the seafoam. Big diff? No. Small diff? Maybe with the seafoam it cleaned some junk from the worn 180,000 mile 258. Oil pressure still very low but still running.
