So with all of these "special esters" can I bypass the maintenance dose of auto-rx?
Those interested in finding out GC's composition.....come in!!

The esters we are still studying are for lubrication primarily, not cleaning like Auto-RX.
Zoil as a lube formula still is focused like all PCMO's on lubing not cleaning.
I highly recommend using our oil analysis to determine when to clean with Auto-RX to optimize cleanliness.
I still add LC to my Zoil when used to control oxidation, and it is very oxidatively stable on its own.
As far as one or both of these sourced esters in the other forms of Zoil I doubt it for 2 reasons, 1) they are expensive,2) the Zoil sample we are testing was made in Europe.
The testing can only address the ZOil that was tested not the whole line of other oils. If through this testing we can ID that possibility I will surely share it here.
Remember the test is not finished and the final results are not complete. I will share more about viscosities,bases, adds, including ester adds and bases.
The key for now that I wanted to get across to all here is that this PAO based oil uses PAO based esters that are not normally seen in the popular GRP4 PCMO's.
Harry thanks for contributing to the effort.
Hopefully through this process we can ID other lube formulas and get people the data that they need to make prudent and value based decisons about lubricants. Especially considering the fuel cost critical times, something Dyson Analysis has been doing for a long time.

Well Terry, this makes me even more anxious waiting for my analysis from you on my UOA. Maybe I will have to put my $1 qt M1 in my other vehicle and keep using GC.
So why would Castrol want to use an ester that's more expensive? Why not just use esters that are already avalible? There must be some reason for using it over the others. Are there any other specific industries that use such a thing?

First off, these esters are COMPLEX (see Interesting Articles section on white papers), and very viscous esters, and have been used in industrial gear lubes for at least the last decade.
My suspicion (theory) is that a German company is blending this for Castrol using those complex esters supplied by certain German additive (elf factory) companies.
Germans seem to like motor oils with cutting-edge chemistry.
Thanks Molakule! Now, I know why my engine runs so smooth and quite. So, in your opinion, is Castrol making any money importing this stuff to the states, and could an equivalent mix be made here for $4-5 a quart?
Nice.
Now can you do a Haiku?

BRAVO!!!
You are mean
If you attack the green
I truly apprecite al the efforts here guys. There is a lot of buzz about 2 different GCs now. I hope whatever we get in the future is sourced from Germany. If so, it will of course, be top-quality. This fluid has given a bump to Castrol and even maybe given them the edge in the USA. People should take Castrol more seriously. Anyway, people are STILL grumbling about G-III base and Castrol "ripping people off". I want to just repost this rant in which I explain why it doesn't matter, or "I don't really care" what GC is made of, beyond novelty value. I owe BitOG for a lot of learing and rational thinking excercises.
Thanks.
Thanks.
I'm not a GC user but I was thinking of giving it a go based on the results posted here. Now I'm going to wait again. It's nice to know that there's a good reason for its great results, super-esters, but we have no idea if they're in the gold. I like the idea of the base oil being good enough to function well without heavy adds. If the gold tests as special I may try it but for now, it's just another good oil. If it's grp3 and super-ester, that wouldn't bother me. I bet the results would be similar. No super-esters would. I'd like to think that super-esters and super POAs (supersyn) are going to continue to become more common.
Note to Canadians: All grades of Castrol Syntec, including made-in-Germany 0W-30 grade, is on sale this week at Canadian Tire stores.
