BITOG appears to have deleted the Cermax thread. Could someone document, in a non-flame, non-boosterism manner, the current state of knowledge of this additive?
thanks!

In the BITOG-environment, I don't think they will find out much. I am using it in two different cars, and it does what it states to do.

Those on BITOG who tried it liked it. Those who hadn't thought it was snake oil and didn't want to hear any more about it.

I wanted to here more about it, but they wouldn't offer anymore info, and the guy that was on there was very defensive when asked simple questions.

A search on the Internet revealed to me that there are more than a half dozen ceramic based oil additives on the market today. Not all of those are marketed in the US, although some that are might simply be relabeled products available in other markets judging from the containers.

I haven't as yet found one that is close enough to Cermax to call it similar. The normal application for a gasoline engine with Cermax is but 2 oz. The other products I've been able to find are sold in much larger sizes and don't activate, bond to the engines surfaces, in the same manner. Most say they don't last the life of the engine, suggest a retreatment later on.

I've used Cermax in several engines. The results range from subtle to significant. In manual and automatic transmissions I've found that you can either feel / hear a difference or you can't. I've not been able to feel a difference using Cermax in a differential.

Got any before and after UOAs?

I've tried to make a science project out of two vehicles. I did "before" compression checks and UOA. It will be Spring most likely before any "after" testing is performed.

One vehicle had never been ARX'd. The other vehicle had been ARX'd twice, which brought it's oil consumption down from one quart every 1,700~miles to a quart every 3,000~ miles.

Checking 1,000 miles into the Cermax treated oil change interval the dipstick was still on full.
