Engine oil LIQUI MOLY or PENNZOIL

Mk7.5 GTI 2019, bought new and ran 0W-20 for the first couple years for warranty (approx 70k) and then switched to Liqui Moly Top Tech 4200 / 5W-30.

I'm curently at 134k and no issues, I'm switching to the leichtlauf 5w-40 on my next service for the extra protection and because I can get it a few dollars cheaper than the Top Tech 4200.

For the money, Pennzoil can't be beat, and I say that considering you can usually get it from Napa or Amazon around $7/qt. Idemitsu is also great, but hovers around $8 or $9/qt on Amazon or Napa.

Pennzoil Ultra Platinum 5W 30 gas to liquid base oil construct $26 for 5 quarts at Walmart or Amazon and is perfect for EJFA engines. People running 0w20 in these fbs and fas and ejs are just destroying their engine. I run the 5W30 pencil Ultra Platinum. I would get the mow tool but it's just really not worth it. I changed my oil every 2,000 mi and the gas to liquid technology. Making your base stock backwards from natural gas gives perfect polymeric structure and their additive package. It's just smoking!  I can get three 5 quart bottles for for $75 on subscribe and save from Amazon delivered plus tax. I think the 5W30s The Sweet spot. Unless you're tracking it then I'd go up to the 0w 40 in the Pennzoil Ultra Platinum. But you have to realize that the same company that makes the base stock oil out of natural gas also owns the additive package company and they run a a 48 Esther ad pack in this and it's just tremendous oil. If I had higher mileage I'd be running. Probably Valvoline 5W30 restore and protect it. Cleans the ringlands, wrist pins, valve train etc. But since I changed my oil so frequently, I always stay with the pennsville Ultra Platinum. I don't think you can be eat it at $0.16 per ounce it's just bulletproof to thermal oxidation.

Moly is 100000% better than whatever the fuck they use at the dealer. I swear, the moment I decided to start taking my VW to an indie shop that works on exclusively German cars, and asked them to use LiquiMoly, my car has run significantly better.

2013 Volvo XC 90. Owned since new, only used Penzoil Euro L formulation, all synthetic, 10W-30 and 143K miles later I had to get rid of her because I left the country. No engine issues at all.

Switched to Pennzoil Platinum for my current car and the engine is noticeably quieter (doesn't have the same mild clattery-ness from the valvetrain like with Mobil 1), and it doesn't burn either

I run liqui moly 4100. I run 5w40 because I want something a bit thicker than what the manual calls for.

Liqui Moly Toptec 4100 5W-40 works if you feel like you need something thicker, but these diesels don't run crazy hot like gas + turbo engines.

LiquiMoly is a line of many products, some are API/ILSAC oils for American and Japanese cars, some are ACEA/Euro oil spec oils. In general they are decent products if you are buying the top end of their line.

I used Pennzoil before but felt real cheap quality and used to get darker before the competitors. I moved to Mobil 1 or Castrol GTX and felt the difference in smoothness.
