Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

13 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I was looking for the different motor oils that were Porsche A40 approved. Liqui Moly 5-40 came up. I don't remember anyone talking about it in any of the 5000 oil threads. So I was just wondering if anyone is using it and how has it worked out for you? Thanks.

POST 3Original post

What oil do you use / should I use is a taboo topic. Been discussed too many times, many hurt feelings and purse swinging. Sometimes their husbands even chime in. If you don't just search oil or any related topic, you're really just wasting our time we could be spending discussing seat belt stitching color. I personally use straight Slick 50. I believe the hype. That, and Split-Fire plugs. As for oil? I like the topic. The car says 0-40 Mobile 1. It coats the moving parts. Some on here know in great detail how different oils have additives and the ability to bond to or protect moving parts better than OEM based on the real ability to perform better under extreme conditions. As with anything on these cars, there's aftermarket crap for all of it. Some really does offer noticeable or proven advantages.

POST 4Original post

There are over 100 Porsche approved A40 oils. Even one called Elf. I always liked that name. Some of the best Porsche approved oils are: Mobil 5W50 Motul 5W40 Excess Some of the best non Porsche approved oils are: Red Line 5W40 Joe Gibbs DT40 I've used all of these except Motul. Currently hooked on Mobil 5W50. Based on over 100,000 Porsche miles in 2 different water cooled cars (987S Boxster and now 991S Carrera PowerKit).

POST 5Original post

Liqui Moly had trackside banners at COTA in Austin for MotoGP and they have monthly ads in Panorama and Roundel and Star, so they certainly would like our business. Since I do as much "made in Germany" as I possibly can, maybe I'll get some next time.

POST 6Original post

Remember, all it takes to get an approval is cash up front...

POST 7Original post

Yeah, Porsche is really a disreputable company that way. Why do we even own them? Of course the oil company has to pay the independent tester ... but the oil has to pass.

Really? They don't have to meet any factory specs huh? Just flash some cash and Porsche will put them on the list? Jesus.

POST 9 / ORIGINAL POSTEROriginal post

Well the forum was a little slow for the last week, so I thought I'd stir something up lol. No but really I've used Mobil 1, Castrol, and Motul. I was just wondering if anyone was using it. I know some peps say to use an oil high in zinc, but none of them really say how much is in there oils. Just wondering if anyone used it or not. Disclaimer I don't own a cat, nor do I hate them

POST 10Original post

Quotes source post: 450911

Only the API requires testing of oils for certifications. Guess what, they use two base engines for all the certs, and neither is anything close to a Porsche. Money can buy anything, even a decal under the deckled of a vehicle with a certain brand name on it.

POST 11Original post

Money can buy almost anything...but at which costs? Reputation is the highest good/asset a company can possibly have (of course next to its employees). So companies set up market barriers of all kind to "protect" their high good "Reputation". The more equal the brand reputations are, the lesser the "costs" to paticipate from the bigger brand. uhm...i am rambling... My dealership used Shell last time, I will have a serious talk with them...put my foot in the ground and ask for Liqui Moly But honestly I have no clue about oils, so if the specs "seem" the same, the only thing i can rely on is "brand reputation"...and Liqui Moly at least wins a lot of prices for their oils, so that will turn into "Reputation" later. uhm...i am rambling again... I will speak with my dealership.

POST 12Original post

I doubt Euro manufacturers care one whit about AMERCIAN petro institute. Mercedes, Porsche, BMW, VW-Audi ALL specify testing by independent labs to verify compliance with THEIR specifications, which go beyond generic EUROPEAN specifications. Euro specs are ACEA, not API, and here's what Wikipedia says about ACEA Go ahead and put non DPF-safe motor oil in your diesel and see what you get. For a Mercedes that will have to be 229.51. 229.5 doesn't get it. The rule is don't even top up with noncompliant oil.

POST 13Original post

I have it in my 2001 at the moment - seems to run nice and smooth. I emailed Liqui Moly and they recommended 'Liqui Moly 2332 Leichtlauf High Tech 5W-40 Engine Oil' as the best for my car, so I ordered a couple of 5 litre jugs through Amazon.
