What customers say about "Key Specs"
Liqui Moly Synthoil Premium 5W-40 Synthetic Motor Oil
  • I have used Castrol and Mobil 1 in my Audi which are both good quality, but this stuff is way better. The engine idles noticeably smoother and seems quieter. I'll be using Liqui Molly from now on.
  • Was recommended this by my father in law whom uses these for years with his audis. I use this on my TT Quattro 01 Easy to pour. Definitely runs smoother than Mobil.
  • As soon as I bought my 2013 VW CC, I drained whatever oil was in there and replaced it with LiquiMoly 5w40. Car seems to start easier and has more power.
  • Now I've been using LiquiMoly for my older Volkswagen Passat 1.8T/B5 for about a couple of years. For this time, Ive noticed my engine making a lot of noise. Now this could be due to a lot of things considering my car is old. I also noticed that my car has been using up more oil.
  • This oil was recommended to me by a seller and I bought it without investigation. The following morning when I started the car at 28 degrees F I heard the unmistakable noise made by unprotected metal to metal friction.
Mobil 1 Turbo Diesel Truck 5W-40 Synthetic Motor Oil
  • My Peterbilt (12.5 liter) may spend winters in north North Dakota and some hot months in Far South Texas. I'm pleased that the oil pressure is normal under these wide temperature swings. Buying ten gallons of this oil took some thought but I'm happy with the results.
  • This oil gets excellent ratings in used oil analysis. I used it in my '06 5.9 Liter Dodge Cummins turbo diesel truck. The 250,000 mile engine only consumed 1/2 quart of this oil over 6000 miles. As always, ensure this oil is appropriate for your car before adding it to the engine.
  • Oil is thin for easy start up and circulation, gets thicher when needed. This synthetic oil holds up better to the torture of the turbo
  • I have been using Mobil 1 product for more than 20 years. You will never go wrong with there product.
  • To rate the effectiveness or lubricity of this oil, the detergents it contains, etc. are beyond my capabilities. I have an '01 VW Jetta Diesel that I use this oil in. I can say that the engine is slightly quieter with this oil.

What customers say about "Features"
Liqui Moly Synthoil Premium 5W-40 Synthetic Motor Oil
  • Been using this stuff for many, many years on both my BMW and VW vehicle while driving on the autobahn at high speeds!!
  • I have a MK V GTI with a BPY engine and it seems to prefer this oil. Maybe you are like me and your GTI consumes a bit of oil. Switching to this and cleaning the intake valves really cut the consumption down to nearly none. I have no complaints.
  • I've been using Liqui Moly products in my BMW and Mercedes for some time now. They have some of best synthetic oils on the market. Highly recommended. This is the ONLY synthetic oil I use in my cars. I LOVE it!!
  • I have used this for my MK6 GTI 2.0TSI for 2 years now. It is common for direct injection engines to burn a bit of oil but I have found this oil to stay at the same level through out the 5000 mi that I let it run prior to the next change.
  • Put this in my 2012 VW Eos. Seems like quality oil. No issues so far and my engine seems to run a tad more quiet than with the previous oil it had. I will stick with Liqui Moly for my future oil needs.
  • The actual product came in blue color and realise i bought the wrong grade.The picture is misleading despite the content on the bottle itself is correct.
Mobil 1 Turbo Diesel Truck 5W-40 Synthetic Motor Oil
  • I use this oil for my Lotus Elise because it is one of the few oils that still has high ZDDP (a zinc additive), and Lotus recommends a 5W40 weight. High ZDDP extends the life of engines that have high pressure sliding surfaces, which is more common in high compression engines.
  • use only this motor oil for our F250, great product, highly recommended and great price - thank you
  • Mercedes strongly suggests Mobil 1 and having a diesel the 5w-40 turbo diesel lubricant in my SUV is just one more thing NOT to worry about " THAT's A GOOD THING" :)
  • I own a 1998 one owner Dodge PU with the Cummins Turbo Diesel. I have used Mobil 1 for every oil change since it was new. It is a superior oil. I change my own oil.
  • I have a 2005 Silverado 2500 with LLY duramax diesel. I have used mobile 1 turbo diesel since new. I now have 351000 miles without ANY problems, truck still runs like new, I have original injectors and turbo, I change oil using vehicle oil monitor, usally at 10000 miles between changes .
