I'm thinking not to follow the rules.. what you all think? Worth it? Im not sure the EO that my SC suggest would be good for ny car

What is the difference between:

1. Liqui Moly TOP TECH 4100 5W-40 (Fully synthetic)
2. Liqui Moly SYNTHOIL HIGH TECH 5W40 (Fully Synthetic)

thank you very much for your mail and for your interst in Liqui Moly products.

We are a German oil manufacturer and in the German market and arround, there is no API licensing necessary. But we know for the Asian and American market it is very good to have. So wa are in work for API licensing with our "Special Tec" oils, which are very necessary in the Asian market!
Sorry, but you have to wait some time, till the licensing is official!

If you have any more question, contact us again!


Mit freundlichen Grüßen / Best regards

Hi Liqui Moly, I would like to inquire if you guys are still licensed/certified by the American Petroleum Institute (API) and is the mentioned API ratings/certification in your products legit? I remembered few years back i have verified that you guys were indeed in the directory however i can no longer find your company/nor your products anymore. (perhaps they have been renamed or i have searched incorrectly?) Appreciate your response in this matter which will restore my confidence in your products, thanks.:

Haha ADVAN I have ALMOST similar question as well...

What is the difference between LQ TOPTEC 4100 and 4200?

From what I've read on their website, seems like 4100 is only suitable for diesel cars and 4200 is suitable for gasoline and diesel.  Can anyone confirm this?

Oh, ADVAN, you are able to get LQ Synthoil High Tech here?

top tech is NOT fully synthetic:
http://www.liqui-moly.de/liquimoly/produkt...ocument&land=GB

also liqui moly is no longer API certified for a very long time.

here's what i got from their representative

So u not recommend Liqui Moly?

How about Rotal Purple HPS and Torco SR1?

not really.

it's just my personal (read: anal) preference towards people claiming certifications they do not have.

royal purple i have no experience.

SR-1 is highly recommended and it is also API SN certified which i've gone as far as 16k km OCI with very minimal degradation (search for my previous post within this thread btw)

the cleaning agents/properties also not bad as my engine is sparkling clean when i open the top to replace valve/rocker cover gasket and adjusting valve clearance

=edit=
to make it clear and to avoid people using my words against me, i have nothing against LM besides what i've mentioned. and i have personally used their semi synthetic MOS2 and i am STILL using their MOS2 for my sister's kancil and i've used their various products from ceratec to engine flush and they've always worked as advertised so if you're asking me if i would recommend LM or not, i'd most certainly do depending on your budget/requirement.

personally, when it comes to semi synthetics, there's very few who can give the satisfaction for LM's MOS2 price vs performance ratio.
i just moved on to fully synthetic for all my cars except the kancil cuz sister don't want to pay so much for a year 1995 car

Hi Quaza, do you happen to know if there is any difference between liqui moly toptec 4100 and 4200?

Ok thanks for your advice.
One factor that made step back is LM don't have fully syn 5W30.

Maybe will give Torco SR1 fully syn 5W30 a try.

Thanks for the link...but I am still confuse about the usage... it seems like 4100 is for diesel cars only and 4200 is for both gasoline and diesel.  I might have read it wrongly...Maybe you can decipher better...

I am referring to 'Intended Use' section in your links

http://www.liqui-moly.de/liquimoly/mediend...c%204200_EN.pdf
if you have API SM/ACEA A classifications, you CAN use it for gasoline:

http://www.opieoils.co.uk/c-789-acea.aspx

now that we have established that...

why the heck there is SN?
ACEA C3 is for Diesel engines though...
all in all; lol still confused.
i guess stick with layman as you've mentioned "seems like 4100 is only suitable for diesel cars and 4200 is suitable for gasoline and diesel."

or personally, i'd avoid those EO
