Zmax is a chemical that soaks into metal. OK....You never have to "add" a damn thing to todays oils....some are better than others....granted....but no additives...waste of money.....about the only things worth adding would be AutoRX and that is to clean and drain.....I use to use Valvoline Oil Treatment...it was good stuff....but hell the add packs in PP 10-30 dont even need that.....
I have learned my lesson about snake oils. However this one comes with a twist. First the store has a 2 for 1 special. Then a $10 rebate per quart. They are not just giving this stuff away, they are paying me to take it.
Now that I have two quarts of this stuff, I am wondering what to do with it.
I have no idea what it is.
Should I try this treatment in my motor?
I am thinking about using it in the wifemobile (MonteCarlo 3.8 V6)
Sarge: I could use your insight on this one.
The residuals that shit leaves in the passages bothers me frankly. I would give it to a Mustang guy or throw it away.

Royal Purple. No paricular reason why. After reading this may change. Only Purolator filters.
Mobil 1 Synthetic Extended Performance...just in case I go a little over the 3,000 mark...and stupid me just found out that there are Mobil 1 filters :suicide: so that's on my next oil change.
Castrol dino works. always slippery even after a missed change
:ar:
I don't have time to sift through all the posts. I have been experimenting with oils lately. I have used Wal-mart's SuperTech Synthetic 10w30 with a Delco filter. I switched to Valvoline Full Synthetic with a Delco Filter. I switched again to Valvoline Synthetic with K&N filter. I now am running RP with a Delco filter. After reading through some of this, I think that I am going to switch to Purolator filters for good.
Being that this car sees more track time than street use. I monitor my guages like a hawk. I noticed when switching to the K&N filter I had a little more oil pressure. I guess the Delco filter is a little more restrictive.
I use a blended oil, Penrite HPR10 witch is in the 10w50 bracket. The filter I use is a Ryco unit. (Both these Brands are local to Aust)
PS since the temps in Sydney rarely go below 0c (that's 32F) I don't see the need for thinner oils.
Why all the switching? What are you after? Who is doing your UOA's? Don't confuse pressure with flow rate.Quote:

Running too thick of oil actually wears the bearings out as the oil is too thick to get to where it needs to be and lubricate.....Quote:

Many hot rodders live by the adage that more is better. For example, if I am running 10W-30 motor oil, then 15W-50 should be way better for my car. This is generally not the case.

Probably some of those same hot rodders who still insist that Fram oil filters are the best.Quote:

Good/Bad idea?
i would say bad. just because i wouldnt like mostiure to get in the hole. just me though
I did not think about moisture. Then again, I live in a very dry valley. It begs the question: How long to drain? This assumes you change your own and have the time.
i wait about 30 min when im not in a hurry. or when i buy a used car. like my work trucks, when i change the oil i pour a little clean oil in and let it drain out to "flush" some of the grimmy crap the guy before me was using.Quote:
