LIQUI MOLY Top Tec 4100 SAE 5W-40 | 1 L | Fully synthetic engine oil | SKU: 2329

Used on Audi A5 engine runs very smooth and oil at 5000 mi looks brand new still great product

Works great. Container is marked so you can see how much you've used and the top becomes a spout when you open it, pouring is easy. The mileage sticker on the bottle that you put on your windshield is a bit too adhesive and hard to remove when you change it, but other than that minor detail, I can't say anything bad. I use this in my 2004 VW Jetta TDI with 277,000 miles, as this is what the previous owner swore by. I share his enthusiasm for this product now and highly recommend it to anyone looking for a high quality synthetic for their diesel.

Excellent oil product. I would expect nothing but the best from Liqui Moly. I have run a lot of miles on this oil with oil changes every 3000 miles. Recently had the valve cover off and the inside of the engine looks like new.

I usually prefer Pentosin oil in my TDI, but this was on the list of blessed oils for my (now) beater MkV A5 TDI and available via Prime.Liqui Moly has a proven track record of providing high quality lubricants, cleaning agents and additives for the European automotive market. I especially like their Diesel Purge. Dirty injectors? As far as I'm concerned, that's the only way to clean them without removing them from the motor.When I saw that my preferred Pentosin oil wasn't available via Prime, this was a logical choice.

This is the oil you need for a 1,9 tdi pd.

My favourite MBZ mechanic says this is THE product for my old MBZ. I'm sure it's just as appropriate for a new one which I personally do not own.My wife drives a Volvo and my other favourite mechanic takes care of her car including oil.

I still change every 3 to 4 thousand but this and other liqui molly products are the best

505.01 spec for pump deuce Volkswagen tdi motor 2005 2006. Seems to run good as expected for a higher quality European oil for a European car. Don't skimp use the proper oil for your vehicle or one that supersedes it if available. This oil helps fill your cam lobes helping to prevent camshaft failure's from what I've read.
